Questions, answered.

Two products, one account. Bindery (bindery.infinitelibrary.ai) is the AI book studio: describe your book to the agent and it drafts the words and typesets real, print-ready pages as you watch — then narrates, prints, and publishes it. The Infinite Library website is where books are read, personalized, and sold: the public library, the “For You” feed that writes short books for one reader, audiobooks, fan fiction, and author royalties.

The same email signs into both. Both are made by Infinite Library SAS, an independent French AI book company founded in 2024.

Anyone with a story, an expertise, or a pile of material who struggles with time, structure, or finishing. Authors use Bindery for novels, memoirs, business books, family histories, poetry, cookbooks, photo books, children’s books, yearbooks, and more; companies order custom editions in bulk; readers use the library and the “For You” feed for books written just for them.

We call it augmented authorship: you bring the vision, characters, and voice; the AI brings structure and a first draft; you revise and finalize, so the creative identity stays yours.

Open Bindery and describe your book — you can try it as a guest with a small one-time taste of credits, no account and no card. A free account adds 800 studio AI credits to start, unlimited books, and a free watermarked proof PDF of any book at any time.

A guest book lives in one browser, so use the “email me a link back to this book” row if you want to find it again, and sign in from that same browser to fold it into your account. You pay only when something leaves the screen — a membership, the clean files, or printed copies.

No. Sign in with Google or with a one-time email code — no password, any email provider. In the iPhone and iPad app, a six-digit code arrives in your inbox. One account spans Infinite Library and Bindery: the same email signs into both, and a membership bought on either side shows up on the other.

Your first typeset pages appear in minutes, and the agent keeps composing as you steer. A full-length grow to 60,000–80,000 words usually finishes the same day, and most books go from idea to a finished, print-ready proof in days rather than months. Raw material moves fast too: a two-hour interview recording transcribes in a few minutes. Printing adds production and shipping time, which the order quote shows before you pay.

Any popular print format: novels, memoirs, and poetry; business books and family histories; photo books, cookbooks, comics and graphic novels, children’s picture books, magazines, planners and journals, workbooks, yearbooks, and booklets or zines. Say what you’re making and the agent sets the book up with the right trim size, color interior, and binding for that kind of book — square or landscape sizes, lie-flat coil, saddle stitch, paperback, or hardcover — and the order screen recommends the matching print product.

Bindery is a web app — nothing to install — and works in any modern browser on a desktop, tablet, or phone (on a phone the proof toolbar shows icons instead of labels). You can pin it like an app: Chrome and Edge offer a one-click install, Safari on a Mac uses File ▸ Add to Dock, and Safari on iPhone or iPad uses Share ▸ Add to Home Screen. For reading and listening there is also the Infinite Library app for iPhone and iPad on the App Store, which includes the studio’s front door.

The Infinite Library website is available in eight languages — English, Spanish, French, German, Italian, Portuguese, Japanese, and Chinese — switchable from the site’s own language menu. Bindery’s interface is in English, but books can be written and typeset in many languages: right-to-left scripts such as Arabic, Hebrew, Persian, and Urdu get dedicated fonts and layout, and Chinese, Japanese, and Korean typeset correctly too. The Translate tool renders a finished book into 110 languages, “For You” books can be generated and read in over 50, and the Librarian support chat answers in whatever language you write.

Chat tools hand you text in a chat window; Bindery hands you a book. The agent is built for book-length work — it keeps your whole manuscript in context as it writes, typesets real pages as you talk (chapters, running heads, a designed cover), checks the book with a free nine-point editor’s read, and produces files a printer or a bookstore accepts. When it’s done you have a print-ready PDF, an EPUB, a Word manuscript, and a bound copy on its way — not a wall of chat to copy-paste.

Drafting tools like Sudowrite or ChatGPT give you text; typesetting tools like Atticus or Vellum lay out a manuscript you have already written; KDP is a place to upload finished files. Bindery covers the whole pipeline — drafting, typesetting, cover, audiobook, print, and a storefront — and the files it produces are what KDP and IngramSpark accept, so you can still publish anywhere. We keep honest, hedged comparisons at infinitelibrary.ai/comparisons.

1. Tell the Bindery agent your idea — or import a Word, PDF, EPUB, Markdown, or text manuscript, paste YouTube links, drop in transcripts and notes, or let it interview you chapter by chapter.
2. It drafts the words and typesets real pages as you watch; revising is the same conversation, and automatic checkpoints let you rewind.
3. Run the free editor’s read, download the free watermarked proof any time, and unlock the clean files when you’re ready.
4. Order printed copies, narrate an audiobook, or publish to the library and keep 95% of royalties.

Yes. Import a Word (.docx), PDF, EPUB, Markdown, or plain-text file and the agent typesets it into real, print-ready pages — images inside the file are extracted and re-placed as proper figures. A legacy .doc file just needs a Save As to .docx first. From there it can leave your text exactly as it is, or edit, restructure, and extend it in the same conversation.

Yes — that pile is a first-class starting point. Choose Notes when you add a book and drop in meeting transcriptions (.vtt/.srt exports from Zoom, Teams, or Otter work as-is), customer interviews, voice-memo transcripts, journals, and research notes — or paste text straight in. The agent reads every word before writing anything, maps the themes, proposes what the book could become, then writes real chapters in your voice, grounded in your material — structured by theme, never one chapter per meeting, never typeset verbatim, never invented. If real names appear in the transcripts it offers, once and early, to anonymize them.

Both. Use the microphone in the composer to dictate a message, or upload recordings (m4a, mp3, wav, webm, mp4, or ogg) — up to 6 hours per recording and 100 MB per file — and they are transcribed at 15 studio credits per minute. A two-hour interview transcribes in a few minutes. Voice notes longer than ten minutes are attached as recordings rather than dictated. Transcripts don’t yet label who said what, so a two-person interview reads as one flow of text until you tell the agent who is who.

Yes. Paste your video links and Bindery reads each video’s transcript — free — then the agent finds the through-line, organizes the material into real chapters, cleans away the spoken-word filler, and typesets a print-ready book in your voice. Videos need captions, and auto-generated captions count, so almost every video works.

Instead of writing from a brief, the agent asks you questions chapter by chapter — about the people, the turning points, the details only you know — and writes each chapter from your answers. Type or dictate your replies. It also works on a finished book: open an interview to revise by conversation, and the agent folds what you say into the existing pages.

Just say so in the book’s chat — “tighten chapter three,” “make the chapter openers more dramatic,” “switch to a warmer serif” — and the agent rewrites and re-typesets; re-composing is free. Type / for the command menu (interview, sources, grow, cover, translate, order, publish, audiobook, screenplay, music, export, bookstore, certificate, share, contribute, designs, advisor, review, rewind), ⌘K to search your books, files, and actions, and ⌘B to open the manuscript sidebar. Press Esc to stop the editor mid-turn, ↑ to recall your last message, and ? for the full shortcut sheet.

As long as you like within print limits. The Grow command offers four rungs — Novella (40,000 words), Novel (60,000), Full-length (80,000, the recommended default), and Epic (100,000) — and quotes an estimate before it starts (roughly 15–45 studio credits per 1,000 new words, depending on the model). Growing works in reverse too: ask the agent to tighten an overlong book. For print, a paperback runs 32–800 pages, a hardcover 24–800, a coil-bound book 2–470, and a saddle-stitched booklet 4–48.

Yes. Choose “Continue a series” in the New Book dialog and add the previous volumes (Word, PDF, EPUB, Markdown, or text). The agent distills a series bible — canon, timeline, open threads, and your voice — and writes the next volume from it. It needs a signed-in membership account. Otherwise each Bindery book holds one manuscript, so a standalone book doesn’t know about your other books unless you give it to them.

Anthropic’s Claude models, chosen from a picker in every book: Fast (the default, and what free accounts use), Recommended, Advanced, and Most capable. Each step up writes with a stronger model and spends more studio credits per turn, and the three higher tiers are a membership feature. The typesetting itself is real LaTeX composed by the agent. Infinite Library is an independent company that builds on Claude the way it builds on Stripe — it is not Anthropic, and it never trains models on your manuscripts.

Run The Editor’s Read (type /review): nine checks — prose, composition, title, byline, chapters, balance, length, blurb, and cover — each with a one-click fix, free, no credits and no model call. The Second Draft shows you, once and free, a passage rewritten side by side by the entry paid model so you can judge the upgrade. Page through the free watermarked proof, and before a bookstore edition run the free IngramSpark readiness check. The printer validates the files again before anything prints.

Yes to both. The Cover tab (a 3D book beside the Proof) offers three routes: design it with the agent (generated art costs 50 studio credits per image, charged only when it succeeds), upload your own artwork, or choose a clean typographic style. A book with no designed cover still prints with a typographic cover carrying the title and author. The PDF proof shows the interior only; the cover wraps around at print time, sized to your exact page count.

A portrait session from one selfie. Upload a photo, and a director model studies it, writes a brief for each look, and edits your selfie into a set of author portraits — then reviews every shot against the selfie, reshoots misses at our cost, and drops anything that still isn’t you, never charged. Each finished photo costs 100 studio credits: free accounts get two photos free once the open book has at least 200 words, and members get the whole first set of four free. Photos come out at 4:5, about 896 × 1120 pixels — a crisp 2-inch print at 300 DPI — and land on the About-the-Author page, the back-cover bio, and your storefront byline. It needs an account.

Yes. Type /translate and choose from 110 languages, including right-to-left scripts with their own fonts. Translation runs on studio credits — 20 per 1,000 source words, multiplied by the model you pick — and you get a free preview of the translated opening first. If your balance runs out the job pauses and resumes where it stopped, without re-charging finished passages.

Be specific in the conversation (2–3 sentences beat one word). State clear constraints — “modern setting with contemporary infrastructure; avoid poverty stereotypes.” Name relationships consistently. Provide sensory details from your actual memories. Ask for one chapter first to verify tone and voice before the full draft, and use the free Second Draft comparison before upgrading the model.

Yes — every book keeps automatic checkpoints: before each agent turn, on every manual save, before a fresh chat, and before a rewind, so a rewind is itself undoable. Press ⌘K and type “Rewind” (or type /rewind) to restore an earlier checkpoint; the newest 40 are kept and manual saves are kept forever. A rewind restores the writing and design only — sharing, collaborators, and publish state stay as they are, so it can never un-share or un-publish a book.

Yes. Bindery, our book studio, is free to start: describe your book to the agent and it drafts the words and typesets real, print-ready pages as you watch — designed cover included. You can try it without an account, and a free account comes with 800 studio AI credits to start — a one-time welcome allowance, not a monthly one — unlimited books, and a free watermarked proof PDF of any book, any time. No credit card. You pay only when something leaves the screen: a membership, the clean print-ready files, or printed copies.

Drafting and typesetting are free, and a watermarked proof PDF is always free. One $49 unlock opens all of a single book’s finished files — the clean print-ready PDF, the EPUB, the editable Word (.docx) manuscript, the IngramSpark-ready bookstore pack, and the assembled audiobook master if you’ve narrated it — or they are unlimited on any Bindery membership (Pro is $39/month or $390/year). Printed copies are priced per book, with the full printing-and-shipping quote shown before you pay.

Credits. All three include unlimited clean, watermark-free downloads of every file on every book, priority composing (your composes jump the queue when the studio is busy), the stronger Claude models, your own cloned narration voice, and the whole Infinite Library at no extra charge — unlimited For You reading, and any book read aloud without limits.

• Pro — $39/month or $390/year — 10,000 studio credits a month.
• Studio — $195/month or $1,950/year — 50,000 a month (5×).
• Publisher — $390/month or $3,900/year — 100,000 a month (10×).

Yearly billing is two months free. It is always one subscription: switch rungs in place from the Bindery account dialog and Stripe prorates the difference — never a second subscription or a second checkout.

We don’t sell a lifetime plan. Writing is free to start, and a Bindery membership — Pro from $39/month or $390/year — adds a monthly credit allowance, unlimited clean file downloads across every book, priority composing, the stronger models, voice cloning, and the whole Infinite Library at no extra charge: unlimited reading, and every book read aloud. Cancel anytime; your books remain yours, and pack credits you’ve bought never expire.

Exactly one optional charge recurs: a Bindery membership — Pro ($39/month or $390/year), Studio ($195/month or $1,950/year), or Publisher ($390/month or $3,900/year) — always one subscription at whichever rung, and it includes the whole Infinite Library (unlimited reading and listening).

Everything else is one-time: the $49 file unlock, Bindery credit packs (from $12, no membership required), the “finish just this one” novel upgrade on a For You book ($14.99, when offered), and print orders. Card details go to Stripe directly — we never see or store the number.

Yes. Bindery credit packs are one-time top-ups any signed-in account can buy: 2,000 credits for $12, 10,000 for $50, 40,000 for $160, or 100,000 for $390. They never expire, roll over month to month, and stack on any plan. Members can also switch on auto-refill in Account → Billing — pick a pack and a threshold, get a receipt email with an off switch each time, capped at a few charges a day. (These are Bindery’s packs; the old library credit packs were retired in July 2026, and existing balances stay honored.)

Membership and credit-pack checkouts have a “have a code?” field. Every affiliate’s handle doubles as a code that gives you 20% off — for twelve months on a subscription, once on a one-time purchase — and credits the affiliate who sent you. Founding-member rates were the same figures as today’s list prices, so there is no hidden cheaper tier to hunt for. A rejected code tells you why: expired, not live yet, fully redeemed, or switched off. We never invent urgency — the prices on the page are the prices.

White Glove is human-led ghostwriting, by application: a senior editor and project lead interview you and deliver a published book in about four weeks. Foundation ($15,000) covers the interviews, a full manuscript, professional editing, an ISBN, and online retail distribution; Executive ($39,000) adds Ingram distribution to 40,000+ bookstores and libraries in 150+ countries, hardcover and paperback trade editions, an audiobook in your cloned voice, a book website, and launch assets; Chairman ($79,000+, invitation only) adds translations, 1,000 hardcovers, and a bookstore launch campaign. Billing is by milestone — a third at kickoff, a third at manuscript approval, the balance at delivery — and the $1,000 deposit is refundable until kickoff and credited to the first milestone. Companies wanting custom books in bulk (50 to 5,000 copies, one invoice) get a Corporate Editions quote within one business day.

Yes. Affiliates earn 30% of everything a referred reader pays during their first 12 months — rising to 40% as your active referrals grow — through a personal link, and your audience gets 20% off through it (your handle also works as a spoken code). Attribution lasts 90 days, last click wins, and it spans both infinitelibrary.ai and Bindery. Commissions clear after a 30-day hold that covers refunds and pay monthly by PayPal once your balance reaches $30. Self-referrals are excluded and disclosure is required. Details and free sign-up: https://www.infinitelibrary.ai/affiliates.

Because there are two products. Bindery studio credits pay for the studio’s AI — writing, art, narration, translation, transcription — and arrive as a monthly allowance (800 free, 10,000 on Pro, 50,000 on Studio, 100,000 on Publisher) or as one-time packs. Infinite Library credits are the reading side’s balance: they grow a “For You” book into a full novel at 2,000 credits per chapter, every account starts with 10,000, and new ones arrive only with the one-time “grow this book” purchase (when offered). They are separate balances in separate places, and neither expires. One trap: a Bindery membership includes unlimited reading and listening but no library-credit allowance, so a member’s writing spends studio credits, never library credits.

Prose is metered per turn on the words the model reads and writes, so stronger models cost more. Flat rates for everything else: generated art 50 credits per image (covers included, charged only on success), narration 50 credits per 1,000 characters, transcription 15 credits per minute, translation 20 credits per 1,000 source words times the model factor, songs 300 credits per finished minute, and author photos 100 credits each.

Free, always: downloading any file, re-composing, the watermarked proof, The Editor’s Read, YouTube transcription, the bookstore-pack readiness check, the Certificate of Authorship, and replaying a narration already recorded.

Credits are the library-side balance that powers AI on the Infinite Library website — above all growing a personalized “For You” book into a full-length novel at 2,000 credits per chapter. Every new account starts with 10,000 free credits, no card needed. The one-time packs were retired in July 2026, but every credit you already own stays valid and never expires. New credits arrive with the one-time “grow this book” purchase on the book itself ($14.99, when offered — enough for a full novel). Writing a book itself happens in Bindery on studio credits and is free to start.

Yes — twice over. Credits you bought for the old Studio are the same library balance, still yours, never expiring: they now power the library’s AI, like growing an Infinite book into a full-length novel at 2,000 credits per chapter. And because book writing moved to the Bindery agent, the first time you sign into Bindery with the same email the unused value of your packs is automatically added to your studio budget as a one-time grant at $3.90 per 1,000 credits — the best per-credit rate any membership has ever sold — with no code, no support ticket, and your library balance untouched. Your old Studio drafts make the move on their own too: opening a draft’s link carries it into Bindery with its writing intact.

Nothing is lost. In Bindery a job pauses rather than dies — narration, translation, music, and a long grow all resume where they stopped once credits arrive, without re-charging the chapters, passages, or tracks already finished. A membership allowance refreshes with the next billing cycle, or a one-time pack tops you up immediately. On the library side, a “For You” novel that stopped mid-growth resumes as soon as credits arrive (the one-time “grow this book” purchase covers it); the chapters already written are saved.

In Bindery, the wallet in the header shows your studio balance, and the account dialog’s Billing section lists every grant, purchase, and spend. On the Infinite Library website, Account → Credits & Ledger shows your library balance, purchases, and usage. The Librarian chat can read both for a signed-in account, or email hello@infinitelibrary.ai and we’ll send you a ledger.

A membership’s monthly allowance refreshes every billing cycle. Credits from one-time packs never expire and roll over month to month, stacking on top of any allowance. Library credits — the free 10,000, anything from a “grow this book” purchase, and anything from the retired packs — never expire either. The only way to lose credits is to delete your account.

Free credits are pooled fairly: one device or browser shares 1,000 free credits across accounts, and one internet address shares 5,000 a month. A third or later account created from the same device, or an account created through a hide-my-email relay, is held at 200 credits. Any purchase or membership lifts the hold permanently — and paid features, printing, and downloads are never affected.

Yes — give 150, get 150. Share your invite link (from the Share menu, and as the QR code on the colophon page of every printed copy) and a friend who signs up receives 150 studio credits; you receive 150 when they compose their first book, up to ten rewards a month. Share cards and storefront embeds carry the same link. Bringing paying customers at scale is what the affiliate program is for.

Yes. Every published book in the public library is free to read at infinitelibrary.ai/explore. The personalized “For You” feed writes short editions for you — the first full opening chapter needs no account, a free sign-in finishes the book, and your first two books are free; after that, membership makes it unlimited. Listening (read-aloud) starts with a free preview and is unlimited for members. Some authors sell paid ebooks and paperbacks from their book pages; those show a free preview first.

A reading feed of books that don’t exist yet. Answer three quick questions about what you like and an AI curates a shelf of titles for you; open one and it is written on the spot — a complete short edition of about four chapters you can finish in one sitting, in any of more than 50 languages. Love it? Grow that same book into a full-length novel, chapter by chapter. Find it at infinitelibrary.ai/infinite.

Yes — the same Bindery membership authors use, because it covers the whole Library: unlimited personalized “For You” books and sequels, every book read aloud without limits (in the author’s own cloned voice where one exists), plus the full writing studio with 10,000 monthly credits. Pro is $39 a month or $390 a year (two months free). There used to be a separate $9.99 “Infinite Unlimited” reading subscription; it retired on 2026-08-26 — one membership now covers reading, listening, and writing. Your rate is locked for as long as you stay subscribed — we never raise an existing subscription’s price.

Two paths, depending on the book. A personalized “For You” book: open it in the reader, open the ••• menu, and choose “Grow this book” — pick Novelette (+8 chapters), Novella (+16), Full novel (+28), or Epic saga (+48) at 2,000 library credits per chapter, covered by your credit balance or, when offered, by the one-off “grow this book” purchase ($14.99 — enough for a full novel). Growth stacks — grow, finish, grow again — up to 100 chapters, and a book that pauses for credits resumes where it stopped. A Bindery book: type /grow in its chat and choose a length. There is no “continue” button at the end of a book’s last chapter — these two are the real paths.

Yes — listening is part of the membership. Everyone gets a free daily preview in the reader (about a minute — enough to hear the book, in the author’s own cloned voice where one exists), and members listen without limits, with a generous fair-use ceiling. An author always gets member treatment on their own book. Authors can also sell a studio-narrated audiobook from their book’s page.

The fan fiction area hosts AI-authored, multi-volume series that continue shared universes, free to start. That content is transformative and non-commercial — created by fans for fans, not endorsed by or affiliated with the owners of the underlying works, whose names, characters, and trademarks remain theirs — and we remove or restrict it promptly on a valid request from a rights holder. For books you publish or sell yourself the bar is higher: keep them original or clearly transformative within the law, because infringing work can’t be sold in the library and you are responsible for what you publish.

Buy an ebook or paperback from its page in the library; the author sets the price and keeps 95% of the royalty. For a gift, choose “Gift this book”: you pay now, the author’s royalty accrues immediately, and the recipient gets an email whose link carries the book — they sign in with any email to redeem it, and forwarding the email forwards the gift. Paperbacks bought from a Bindery storefront can be gifts too, with your name, a message, and an optional recipient email.

Yes — Infinite Library: AI Book Maker, for iPhone and iPad on the App Store. Explore is the whole public library, browsable by shelf and searchable, with a native reader in paper, sepia, or night; Listen streams albums and audiobook samples and redeems purchased listening links; the Bindery tab is the studio’s front door, with the live editor chat and the typeset proof beside it on iPad; Account holds your orders, earnings, referrals, credits, and notifications. It is the same account as the web — sign in with the same email and a six-digit code — and a guest book folds into your account at sign-in.

Yes. Once the app is installed, links to a book’s read page (infinitelibrary.ai/read/…) and to the library (infinitelibrary.ai/explore) open directly in the app instead of the browser — so a shared book lands in the native reader.

Memberships, credits, and the file unlock bought in the app go through the App Store, so Apple bills you: subscriptions renew automatically until you cancel in your Apple Account settings at least 24 hours before the period ends, and App Store refunds are requested from Apple. A membership bought on your phone is active on the web the next time the page loads, and vice versa; if it doesn’t show, tap Restore purchases in the app. Plans bought with a card on the web are billed by Infinite Library and managed on your account page — you hold one membership, never both.

Yes. Open the Listen tab (or type /audiobook), hear a short voice preview (about 60 studio credits, quoted first), and choose a narrator: George (warm and seasoned, and the default), Lily (clear and bright — memoirs and children’s books), or Daniel (steady and confident — non-fiction and thrillers). Members can clone their own voice instead. Narration runs on studio credits at 50 per 1,000 characters plus the agent’s script pass — a 60,000-word book is roughly 17,000 credits — and the estimate appears before anything records. Listening in the studio is free, and re-narrating after edits only pays for the chapters that changed.

Yes, with a membership. Record a sample — at least 12 seconds, about 45 is ideal — and tick the consent box (the studio refuses without it). One clone per author; re-recording replaces it, and deleting it removes the voice model from the narration provider, not just from us. A cloned-voice audiobook is never put on sale by default — that takes an explicit switch on your book’s page.

The assembled master (book.mp3) is one of the five files the $49 unlock opens, and it is included with any membership; listening inside the studio is always free. Once your book is published, its page can sell the audiobook to readers — you set the price (default $9, from $1.99 to $99.99) and keep 80%; buyers get a permanent listening link with no account needed, and a reader buying a paperback can add the audiobook in the same checkout. The album page at your storefront plays continuously and is free to share.

Yes, forever. The standalone audiobook fees on the website ($49 for an AI narrator, $99–$249 for a cloned voice) were retired in July 2026 when narration moved into Bindery, but anyone who paid keeps everything: your book’s infinitelibrary.ai/audiobook page still samples, regenerates, and downloads that voice.

Yes. The Script tab (or /screenplay) adapts a finished book into an industry-formatted screenplay — feature film, TV pilot, or short — and you revise it the same way you write: tell the agent what to change. The Fountain source and a watermarked PDF are free; the clean PDF and the Final Draft (.fdx) file ride the same $49 unlock as your other files, never a second purchase.

Yes. The Music tab (or /music) writes your book an album: the agent drafts lyrics from your story, you read and approve every word, then real sung tracks are recorded at 300 studio credits per finished minute, quoted before anything starts. Tracks play on a shareable album page, MP3 downloads ride the $49 unlock, and only the book’s owner can record.

Yes — that is Bindery’s home turf. Choose hardcover, paperback, coil-bound, or saddle-stitched; our production partner Lulu Press prints on demand and ships worldwide. Type /order or use the Order button, pick a shipping option, and you see the full printing-and-shipping quote — with the estimated delivery window — before you pay. Each copy is printed fresh for you; production takes a few business days, then shipping.

Twenty-one curated presets, every one validated with the printer. Trim sizes: 5 × 8, 5.5 × 8.5, 6 × 9, 7 × 10, 8.5 × 8.5 (square), 8.5 × 11, and 9 × 7 landscape. Interiors: black-and-white on 60 lb cream uncoated, full color on 80 lb coated, and a premium-color tier — the printer’s richest ink — for photo books and magazines. Bindings: paperback (32–800 pages), case-wrap hardcover (24–800), lie-flat coil (2–470), and saddle stitch (4–48). Tell the agent what you’re making and it picks the preset; you can change it at the order step.

Worldwide, through Lulu’s print network. Before you type an address the order screen shows “Ships to your country from $X”; then you choose from mail, priority, ground, expedited, or express, each with its price and estimated delivery window. Multiple copies lower the per-copy price and share one shipping charge. Orders to Brazil, Chile, and Mexico need the recipient’s tax ID before we can charge. One thing to know: the printer bills in euros, so your card statement may show a EUR amount with your bank’s conversion — that is the same order, not a second charge.

Every order is listed with live status and tracking at infinitelibrary.ai/account/orders, and you get an email at each step — order confirmed, printing, shipped with the tracking link — plus a check-in around delivery day (if it hasn’t turned up, just reply; that reaches a human). In Bindery the order card can show the exact proof that went to the printer. The Librarian chat can also check an order for a signed-in account, or email hello@infinitelibrary.ai with your order number.

Email hello@infinitelibrary.ai with your order number and a few photos and we’ll arrange a reprint or a refund — the printer normally reprints production faults free. Because each copy is printed on demand specifically for you, a non-defective book isn’t returnable under distance-selling rules; a defective one always is. If the printer’s pre-flight check ever finds a real defect in the files, the order isn’t submitted at all and the charge is refunded automatically.

No. Anyone can order a printed hardcover or paperback, and you always see the full price before paying. The watermark you see on the order preview is screen-only and never printed. A membership is for authors who want every book’s clean digital files, unlimited, plus more credits and faster composing.

Yes. Any order can be for multiple copies; they share shipping and the per-copy price drops. For a group book, contributors can tick “I’d like a printed copy,” and the Order dialog offers a one-tap order for all of them plus yours. For company-scale runs — handbooks, executive manifestos, client gifts — Corporate Editions handles 50 to 5,000 copies as one flat-fee project on one invoice, with a quote within one business day at infinitelibrary.ai/corporate.

Yes. Publish a finished book of 50,000+ words to the public library and keep 95% of royalties — and 100% of the copyright. You set the price: $0.99 to $99.99 for the ebook, $5 to $99.99 for a paperback (where most of the price is printing and shipping). Payouts run through Stripe Connect, you don’t need payout setup before your first sale — earnings wait as a pending balance — and you can unpublish at any time. A Bindery book also gets its own storefront page the moment it is published.

Money moves in two hops. First, us to your Stripe account: every sale is recorded the moment it completes and released automatically the day your payout setup finishes, then on a daily sweep and whenever you open infinitelibrary.ai/earnings — so a royalty is normally released within a day of the sale. Second, Stripe to your bank: on Stripe’s own schedule for your country, commonly a few business days (the very first payout after verification takes longer), with the exact date in your Stripe dashboard via Manage on the earnings page.

The earnings page shows gross, pending, and paid out; what you receive is the pending/paid-out figure, never the gross — for a paperback most of the gross is printing and shipping. Refunds and chargebacks reverse the matching royalty, and taxes on your earnings are yours to report.

Yes. Your export files are KDP-ready — an EPUB for the ebook and a print-ready interior PDF, plus an editable Word (.docx) manuscript — included with the $49 unlock or any Bindery membership, and Infinite Library takes no cut of what you earn there. You’ll need your final files, a cover image (recommended 3000 × 4500 px or larger), title, author bio, keywords, and pricing. There is no direct KDP integration — you upload the files yourself — and on request we’ll walk you through the steps.

Yes, two ways. Self-publishing: the $49 unlock includes an IngramSpark-ready bookstore pack — the interior re-typeset to Ingram’s spec, a wraparound cover with the spine computed from your exact page count, and a START-HERE file listing every number in the order IngramSpark’s form asks for (the readiness check is free; an ISBN is optional, and the pack rebuilds free once you add one). Upload it and 40,000+ bookstores and libraries in 150+ countries can order your book. Done for you: White Glove Executive and Chairman engagements place your book in the Ingram catalog for you. Either way a listing makes the book orderable; shelf placement is won store by store, which is what the Chairman launch campaign is for.

Not to publish in the library or sell from your Bindery storefront. An ISBN matters when you take the book to retailers: IngramSpark needs one (the bookstore pack prints a real scannable barcode when you have one on file), and Amazon KDP can assign one of its own for its print editions. You can buy an ISBN from your country’s agency; White Glove Foundation includes one.

Every published Bindery book gets a page at bindery.infinitelibrary.ai/s/<slug> — a readable address minted from your title that never dies, even if you unpublish. It has a look-inside preview (4–16 pages), a native paperback checkout with an optional audiobook bundle and gifting, your author photo and bio, a shelf of your other books, and a copies-ordered count once at least three have been ordered. You set the royalty per printed copy (quick picks $0, $3, $5, or $8, up to $99.99), which collects on infinitelibrary.ai/earnings. An embed card (/s/<slug>/embed) drops it into a blog or newsletter, carrying your referral link.

Publishing to the public library needs a finished book — 50,000+ words — that passes the content policy (no sexually explicit material, no infringing IP). If a book that qualifies still fails, the hiccup is usually transient: try again in a minute. If it persists, email hello@infinitelibrary.ai with the book’s title and we’ll check the logs.

On the /read page, click the gear (Settings) at the top and switch on “Private.” The book leaves public sale immediately; copies already sold or printed stay with their buyers, and cached pages can take a few days to clear from search engines. Flip the switch back any time.

Yes. Each book’s byline is set in Book Settings and can be any name you like; your account email is never shown to readers. If you’d rather not appear in search engines at all, Settings → Privacy → “Show me in search engines” switches it off without hiding your books from the library.

Yes. Share → Invite adds editors, who write with the agent on their own credits, or viewers, who can read the proof but not change it. Only the owner can publish, print, export, or delete, and recording music, translating, and publishing are owner-only. There is no comment or annotation layer yet — editors talk to the agent directly, and every change lands in the shared checkpoints.

Yes — that is a group book. Share → “Collect contributions” gives you a link (bindery.infinitelibrary.ai/c/…) anyone can open with no account and no app: they add their name, a note, up to six photos, and a voice note recorded on the spot. Contributions land in the book’s files, and “Weave them into the book” writes them in, crediting each person by name and placing their photos. “Reset link” retires a leaked link, contributors can tick “I’d like a printed copy” (only you see that list, and the Order dialog offers a one-tap order for everyone), and Bindery never emails your contributors itself.

The design shelf (bindery.infinitelibrary.ai/designs) is where authors publish a finished book’s page design — typography, margins, chapter openers, the whole page architecture — for others to start from. Starting a book in a design brings the design files only, never the original’s words; the agent then interviews you for yours. You’ll find “Make a book in this design” on any published book’s site and “fork it” on the last page of a shared proof. The designer’s name prints on the colophon of every book started in their design, and they earn $1 per copy printed — paid from our margin, never charged to the new author. A borrowed design can’t be re-listed, though a book inspired by one can.

Type /share. A share link opens a read-only proof anyone can page through, and invites bring in co-writers or reviewers. Share cards — a cover card for social media — come from the same menu and carry your referral link, as does the storefront embed once you publish.

The colophon: a final leaf noting the book was made in Bindery, with a QR code that is your own referral link — so every printed copy can earn you credits when a reader scans it. Don’t want it? Remove it instantly, no re-compose: “Remove this page” on the proof’s last page, the toggle in the Order dialog, or just ask the agent.

You retain 100% ownership of everything you create — the text, the cover, the narration, the design — including full copyright and publishing rights, whether you publish with us or anywhere else. Attribution is completely optional: you are not required to disclose that AI was used. Many authors mention their tools in an acknowledgments or resources section, but it is entirely your choice. We never use your manuscripts or prompts to train models.

Issue a free Certificate of Authorship (type /certificate) for any finished Bindery book: a signed record of the author, the title, and a fingerprint of the text — a SHA-256 hash of the manuscript itself, not the PDF, so a margin tweak or an engine upgrade doesn’t read as “the book changed.” Each certificate has an ID like BNDY-2026-xxxxxxxx and a public verification page at bindery.infinitelibrary.ai/cert/<id>, printed on the document with a QR code. Editing the text mints a new revision while earlier certificates stay valid for the earlier text. It is a provenance record, not a government copyright registration — you already hold the copyright either way.

Not in books you publish or sell: avoid infringing IP — names, worlds, and trademarked characters from existing works — and keep your content original or clearly transformative within legal limits. You warrant that you hold the rights to what you publish, and we remove infringing work promptly on a valid request from a rights holder. The site’s own fan fiction area is different: it is transformative, non-commercial, fans-for-fans content, clearly labeled as unaffiliated with the original owners.

No. Infinite Library does not train AI models itself and never uses your prompts, uploads, manuscripts, or generated books to train models — private or published. The AI providers we build on (Anthropic’s Claude for writing and typesetting, OpenAI for select library and audio features, ElevenLabs for voices, DeepL for translation) process your content to serve your requests under their own terms. You can opt out of analytics where applicable; the full picture is on infinitelibrary.ai/ethics and in the Privacy Policy.

Refundable — system errors are on us:

• An incomplete generation caused by a server crash, bug, or service failure (credits are restored).
• Billing errors: double charges, unauthorized charges, or a valid code that couldn’t be redeemed.
• A printed book that arrives damaged or defective (reprint or refund).

Not refundable — taste and creative direction:

• Dissatisfaction with writing style, tone, or narrative quality; a story that doesn’t match your vision; wanting a different storyline or major rewrites. That is what the free proof, the free editor’s read, and revising by conversation are for.

Because AI generation is digital content supplied immediately, credits and generation features are final once generation begins (the EU right of withdrawal is waived under Article L.221-28 13° of the French Consumer Code), and print-on-demand copies are exempt from returns unless defective.

To request a review, email hello@infinitelibrary.ai within 14 days with your receipt or transaction ID, the purchase platform (web, Apple, or Google Play for older purchases), and what happened — a human reviews every case.

Match the amount and the interval on the receipt.

Recurring: $39/month or $390/year is Bindery Pro; $195/month or $1,950/year is Bindery Studio; $390/month or $3,900/year is Bindery Publisher — the one membership, at whichever rung. Bindery memberships appear as a “Bindery Pro” line from Infinite Library.

One-time: $49 is a Bindery file unlock (or, before July 2026, the retired standalone audiobook narration — the line item says which); $12, $50, $160, or $390 is a Bindery credit pack; $14.99 is a “finish just this one” novel upgrade; $99–$249 is a retired cloned-voice audiobook; $29.99, $99.99, $299.99, or $499.99 is a retired library credit pack; anything else is a print order — which may show in euros, since the printer bills in EUR.

A brief repricing ran August 1–3, 2026: the unlock was $69 and packs were $18, $75, $250, or $590 — those charges are real and the credits stay valid — but recurring charges at the repriced $59/$590, $295/$2,950, or $590/$5,900 shouldn’t exist, so send us any such receipt.

Ambiguous amounts do exist — $390 is the largest pack, Pro billed yearly, or Publisher billed monthly; $49 is the unlock or the old narration fee — so check whether the receipt says year, month, or one-time. Still unsure? Send the receipt to hello@infinitelibrary.ai and we’ll identify it.

A Bindery membership is managed from the account dialog inside Bindery, or from the billing portal on this site (Manage membership on your For You shelf): switch between Pro, Studio, and Publisher in place (Stripe prorates the difference), or cancel — you keep everything until the end of the period you’ve paid for, and your books, files, and pack credits remain yours. A monthly plan can be paused for one, two, or three months from the cancel step; a founding or grandfathered rate survives a pause but a full cancel gives it up for good, and yearly plans can’t pause. A membership bought in the app is cancelled in your Apple Account settings.

Apple. Purchases made through the App Store are billed by Apple, so refunds are requested from Apple at reportaproblem.apple.com (Google Play handles its own older purchases the same way). Contact us if you’d like step-by-step help — and if a store purchase hasn’t shown up in your account, tap Restore purchases in the app first.

Share both receipts with hello@infinitelibrary.ai (or the Librarian chat, which opens a ticket with the conversation attached). If we confirm duplicates we issue a refund or account credit, typically within 5–7 business days once verified. Card details live with Stripe, so a duplicate is always fixable — and one common false alarm is a print order that shows in both your currency and in euros, which is one charge, not two.

Our safety systems block sexually explicit content and other prohibited categories. If your scene was flagged, revise the prompt to be non-explicit — use high-level descriptions or fade-to-black storytelling instead of detailed sexual content. Mature themes, violence in context, and adult relationships are fine; explicit sexual detail is not.

• Sexually explicit material, and any sexual content involving minors.
• Graphic sexual violence.
• Content that infringes someone else’s intellectual property.
• Cloning a person’s voice or likeness without their authorization, and deepfakes.
• Using the service or its output to train or build competing AI models; scraping or bulk extraction.
• Other categories restricted by platform policy and law.

Books published for sale also pass a content check before they go live.

At least 13 to use Infinite Library and Bindery. If you are under the age of digital consent where you live (16 in parts of the EU/EEA), you may use them only with a parent or guardian’s permission and involvement. To sell books, receive payouts, or buy paid features you must be at least 18 (or the age of majority where you live). We rely on these representations rather than verifying age.

Every book published for sale passes a content check, and the discovery gate — including an adult-content classifier — decides what surfaces in search, the app, and the feeds; the catalog the app shows is the same one search engines are allowed to index. Readers can hide, block, or report a book, rights holders can request removal, and takedowns take effect immediately because book pages read live.

Yes, both. Exports: open any book and use Export (or type /export in Bindery) to download your work, or email support with the subject “Data Export” for a full copy. Deletion is self-serve: Settings → Account → Delete account (or ask the Librarian chat). We email your account’s inbox a confirmation link; clicking it locks the account immediately and everything is permanently erased after a 14-day safety window — the same email includes a one-click cancel link in case you change your mind.

Yes. Settings → Privacy → “Show me in search engines” — turn it off and your author page and books are removed from our sitemaps, marked so search engines skip them, and the engines are pinged to recrawl right away. Your books stay in the Library and keep working for readers; they just stop appearing in search results (existing results usually clear within days). Prefer a different name instead? Each book’s byline can be a pen name — change it in Book Settings. Flip the switch back on any time to be discoverable again.

Just want out of search results? You don’t need to delete anything — see “Can I stay out of Google without deleting my account?” above. For full deletion: Settings → Delete account starts it (it covers both products — it is one shared account) — your account locks immediately, your books and author page disappear from the library right away, and we immediately notify search engines that those pages are gone. After a 14-day safety window (one click on the link we email you restores everything), all of it is permanently erased — books, audiobooks, profile, reading history, personal data, and any cloned voice (deleted immediately, including at our voice provider). What remains: anonymized sales amounts where tax law requires them — never your name or email — and books other people paid for stay readable to those buyers with your identity removed. Search results refresh on each engine’s own schedule, usually within days; you can nudge Google with its refresh tool at search.google.com/search-console/remove-outdated-content, or email hello@infinitelibrary.ai and we’ll file the removal for you. Can’t sign in, or no longer have access to the account’s email address? Write to hello@infinitelibrary.ai from any address and a human will verify it’s you and take care of it.

No. Payments are handled by Stripe (and by Apple for App Store purchases) — card numbers never touch our servers. We keep the transaction records tax law requires, and your receipts come from Stripe.

A voice clone is biometric data, created only with your explicit consent and used only to narrate your books. It is deleted the moment you delete the voice or your account — we also instruct the voice provider to delete the voiceprint — and in any case no later than three years after your last interaction. One clone per author; re-recording replaces the old one.

Essential cookies always (sign-in sessions, your language, the cart). Where the law requires it, a cookie notice lets you accept or decline non-essential ones: Vercel Analytics and Speed Insights, Google Analytics/Firebase Analytics, and Google Ads conversion measurement. Affiliate attribution is entirely first-party — a 90-day cookie on our own domain, no third-party affiliate tracker. The full list is in the Privacy Policy.

No — a composing error never deletes your manuscript. Bindery saves automatic checkpoints as it works: press ⌘K, type “Rewind” (or /rewind), and restore the book to an earlier checkpoint. If a generation stalled, refresh and it picks up where it left off. If something truly looks missing, check you are signed in with the same email, then contact support and we’ll dig in.

In Bindery, once composing finishes, the proof pane on the right shows your typeset pages; export controls appear only once a proof exists. Without a membership or unlock, the proof toolbar shows “Free proof” (a watermarked PDF, always free) and “Unlock PDF & EPUB” — the one-time $49 unlock for that book’s clean files. After the unlock or on any membership, the download arrow above the proof saves the clean PDF, and the EPUB and Word buttons sit beside the Proof and Cover tabs (on a phone they are icons). Type /export for everything in one place. Downloads never consume credits.

Almost always a different-email mix-up: check that your account shows the same email you used before (Google and email-code sign-ins with different addresses are different accounts). A guest book lives in the browser where you made it, so on another device it won’t appear until you sign in there with the email you gave the “email me a link” row. The Infinite Library website’s book count covers library books only — Bindery books live in Bindery. Still missing? Email hello@infinitelibrary.ai with the book’s title and a person will dig it out; your work saves to our servers automatically.

Codes are single-use and short-lived. Request a fresh one, check your spam folder, and make sure you are entering the newest code sent to that exact address. If codes never arrive, try a different email provider or sign in with Google instead — one account can use both as long as the email matches.

That is a brief, studio-wide capacity limit on our side — not your account and not your credits, which are safe. Try again in a minute; a stalled compose picks up where it left off. If it keeps happening, tell the Librarian or email hello@infinitelibrary.ai.

Reload the page and confirm you are signed in with the member email. If the button is still there after composing finishes, that is a bug — tell the Librarian chat or email hello@infinitelibrary.ai with the book’s title and we’ll fix your account.

A font without those glyphs. Books in non-Latin scripts switch typesetting engines and fonts automatically — right-to-left scripts and Chinese, Japanese, and Korean included — and when a glyph is still missing the proof shows a “missing glyphs” warning with a one-click fix. If it persists, tell the agent which script the text is in.

For billing: the receipt or transaction ID and the purchase platform (web, Apple, or Google). For credit questions: a screenshot of Account → Credits & Ledger (or Bindery’s account Billing section). For technical issues: the book’s title, what happened, and roughly when. The Librarian — our concierge in the site’s chat — can check order status and answer live; hello@infinitelibrary.ai reaches the same team.

General inquiries: usually within 1–2 business days. Courtesy credit reviews and duplicate charges: typically acknowledged or resolved within 5–7 business days once receipts are provided. Critical generation blockers — anything that stops you composing or opening a book — are prioritized for immediate triage, and we aim for rapid fixes once reproduced.

The Librarian is our AI concierge in the site’s chat (and in the app). It answers from the published help center and guides, and for a signed-in account it can check your credit balance and membership, your sales and payouts, and your recent orders with tracking; it can start the self-serve account-deletion flow, and when something needs a person — a refund, a doubled charge, lost work, a takedown — it opens a ticket with the conversation attached and a human follows up by email. It can’t issue refunds, change your email, or take a book down itself.

There is no phone line — support is by chat and email, and that is where the people who build the product actually are. Everything reaches the same small, founder-led team at hello@infinitelibrary.ai: support, press, partnerships, corporate, and business inquiries. Jobs, funding, and roadmap questions go there too; we would rather answer honestly than guess in a chat.

Infinite Library SAS, an independent AI book company founded in 2024 by Thomas A.Q.T. Truong, its founder and CEO — a French entrepreneur with master’s degrees in Artificial Intelligence (Sorbonne University) and Data Science (ISUP), named to MIT Technology Review’s Innovators Under 35 Europe list in 2023. The company is registered in France with its office in Montrouge, just south of Paris; registration details are on the legal notice page. Meet the founder at infinitelibrary.ai/founder and read the story at infinitelibrary.ai/about.

The writing and typesetting agent in Bindery runs on Anthropic’s Claude models, with a model picker in every book; the Librarian in our support chat is Claude too. Bindery composes real LaTeX to typeset every page, Lulu prints and ships the bound copies, Stripe handles every payment, OpenAI models power select library and audio features on the website, ElevenLabs provides voices, and DeepL supports translation. Infinite Library is not Anthropic and not affiliated with it — an independent French company that builds on Claude the way it builds on Stripe — and it does not train AI models.
