The short answer
Yes — your interviews can become a hardcover, and the working pipeline is simpler than the folder of material suggests. Upload the recordings (up to 6 hours per file) or the transcripts you already have; transcription is quoted in AI credits before anything is charged. Claude reads everything, proposes the book's structure, drafts and revises it with you with the whole manuscript in context, and typesets a live proof of the actual book as you go. Six hours of recorded conversation typically yields 50,000–60,000 spoken words — a complete book's worth of material.
For a family project, the hardcover is usually the right call: it's the copy that gets handed down.
The rest of this page covers the craft decisions specific to this conversion, the exact mechanics, real print specs, and honest pricing.
Getting your interviews into the studio
Drag the recordings straight into Bindery's composer — MP3, M4A, WAV, WEBM, OGG, FLAC, or AIFF, up to 6 hours per file. Bindery measures each file and quotes the transcription price in AI credits before anything is charged; tap Transcribe and the transcript lands beside the recording as readable text the editor works from. Already have transcripts? Attach the .vtt/.srt export or paste the text and skip the transcription step entirely.
From recorded conversation to readable story
An interview transcript is raw ore, not a book. People talk in loops — they start a story, abandon it, return to it twenty minutes later with the crucial detail. The craft move is deciding what the book's spine is before cleaning a single sentence: chronological (a life told in order), thematic (work, love, faith, war — one chapter each), or scenic (a handful of fully-rendered days that carry everything). Each spine asks different questions of the same recordings.
Keep the speaker's actual voice. The temptation is to "fix" grammar until grandpa sounds like a newscaster; resist it. The phrases they repeat, the way they understate the hard parts — that's the inheritance. A good working rule: reorganize freely at the paragraph level, edit lightly at the sentence level, and preserve word-for-word the sentences you can hear them saying. Claude follows exactly this kind of instruction well — tell it whose voice rules the page, and it will move material without flattening it.
Interview projects also grow: once one relative hears about the book, three more want to add their side. Bindery's group-contribution links handle that without you playing secretary — anyone can add memories, photos, or voice notes from a link, no account needed, and Claude weaves them in with credit.

How it works
1. Upload the recordings Drag the recordings into Bindery's composer (MP3, M4A, WAV, WEBM, OGG, FLAC, or AIFF, up to 6 hours per file) — or attach .vtt/.srt transcripts you already have. Transcription is quoted in AI credits before anything is charged.
2. Map the book with Claude Claude reads everything and proposes the book hiding in your interviews — themes, a chapter structure, what to keep and what to cut. You redirect it in plain language until the plan is yours.
3. Draft and revise together Chapter by chapter, Claude drafts from your material and revises to your notes — with the entire manuscript in context, so names, facts, and voice stay consistent from first page to last.
4. Watch it become a book A live typeset proof assembles as you work: real pages, a designed cover, a spine sized from the true page count. The watermarked proof is always free.
5. Order the hardcover Choose the trim and paper, approve the proof, and the case-wrap hardcover is printed on demand and shipped to your door.
The hardcover, specifically
A hardcover is the format you choose when the book is meant to outlast — the family history that gets handed down, the memoir on the shelf, the gift that signals this mattered. Bindery's hardcovers are case wrap (the artwork printed directly onto the rigid case), in trims from classic 6×9 and compact 5.5×8.5 up to 8.5×8.5 square, 9×7 landscape, and full 8.5×11 — black & white on cream paper, full color, or premium color for photo-rich books. Case-wrap hardcovers run 24 to 800 pages.
As the manuscript comes together, Claude typesets a live proof of the actual book — real pages, justified and hyphenated type, running heads, a cover with a spine sized from the true page count. The watermarked proof is always free, so you see exactly what you're making before spending anything on it.
The files that go to print are validated against the printer's own rules first — trim, bleed, spine width from the actual page count — then Lulu prints on demand and ships to your door. One copy for the mantel or twenty for the reunion; no minimum run.
What it costs
Free to start — no account needed to try, no credit card, and a monthly allowance of AI credits on the free tier. The typeset, watermarked proof of your book is always free. Metered work (like transcription, translation, or narration) shows its price in credits before you confirm, so there are no surprise charges.
When you want clean files — press-ready PDF, EPUB, Word — that's a $49 one-time per book unlock, or free with Bindery Pro ($39/month (or $390/year)). One-time credit packs start at $12. Printed copies are priced per copy at order time, printed and shipped by Lulu.
Start free, see the proof
Bindery — the book studio inside Infinite Library — is where this whole pipeline lives: one place that reads your interviews, writes with you, typesets as it goes, and ends in a hardcover instead of a file you still have to figure out how to publish. It's free to start with no account needed to try, the watermarked proof is always free, and every metered step quotes its price before running. The fastest way to know if this works for your material is to bring a piece of it and watch the first chapter appear.
Frequently Asked Questions
How many hours of interviews make a book?
People speak roughly 9,000–10,000 words per hour of actual talk. Six to eight hours of recording usually yields enough for a 40,000–60,000-word book after the loops and false starts are cut. Bindery accepts files up to 6 hours each, so even marathon sessions upload in one or two pieces.
The recordings are rough — phone audio, background noise. Will that work?
Usually yes: transcription handles ordinary phone and kitchen-table recordings well. If a file can't be read at all, Bindery tells you before charging anything, and re-exporting as .m4a or .mp3 fixes most container problems. The transcript is editable afterward, so the occasional misheard name is a ten-second fix.
What are the hardcover options?
Case-wrap hardcovers in 6×9, 5.5×8.5, 7×10, 8.5×8.5 square, 9×7 landscape, and 8.5×11 trims — 24 to 800 pages, in black & white, full color, or premium color on coated paper for photo-heavy books.
How many copies do I have to order?
One, if you like. Printing is on demand through Lulu — order single copies as gifts occasions arise, or a batch for an event; the price and shipping options are shown before you confirm.
Do I keep the rights to my book?
Yes — authors keep ownership of their work. Publish it anywhere, sell it from your free Infinite Library storefront, or keep it entirely private. The platform never takes your copyright.
