The short answer
The bedtime story you improvise can become a real book: tell the studio the hero and the shape of it, pick the 3–5 band and a soft art style, and Claude writes a storyboard with a refrain and a page-turn hook per spread, quieting toward the end; a real image model paints it with a consistent hero; you record each spread in your own voice (free) so it plays on the reading page and in the studio; and it prints as an 8.5×8.5 in colour hardcover, from one copy.
The physical book
Bedtime books are read in the dark, half from memory, so the format leans toward fewer words and a refrain — the 3–5 band writes fifteen to fifty words a spread with a line that comes back — and toward a sturdy square hardcover that survives being read four hundred times.
Every option below is a real, printer-validated product — files are checked against the printer's own rules (trim, bleed, spine width computed from the actual page count) before anything prints, and Lulu prints on demand and ships to your door.
| Option | Trim | Pages | Ink & paper |
|---|---|---|---|
| Hardcover · case wrap · full colour | 8.5×8.5 in | 24–800 | The one by the bed |
| Paperback · full colour | 8.5×8.5 in | 32–800 | The travel copy |
Writing for the last ten minutes of the day
A bedtime story has a job: it winds down. The storyboarder writes the 3–5 band to a read-aloud cadence — a refrain the child can say with you, a page-turn hook on every spread, and an arc that gets quieter toward the end, so the last spreads are the softest pictures in the book (the studio's picture briefs say so, too: warm low light, the hero settling). The moon-boat, the lost star, the animal who cannot sleep — the shapes that work at bedtime are old, and they work because they end in rest.
Your own voice is the feature that matters here. Record each spread in the browser — one press to record, one to stop, a dozen presses for a whole book, free — and the reading plays in the studio's reader and on the book's public page. A grandparent three time zones away records it once; the child hears them every night. A studio narrator is there as well, priced per thousand characters, if you would rather.
Everything else is the standard picture-book pipeline: a storyboard to edit first, character sheets for a consistent hero, twelve art styles (the soft ones — watercolour, gouache, pastel — suit the hour), a free reading page, and the 8.5×8.5 in hardcover.
- Give the refrain three words the child can say — "and then, sleep" — and let it return on every third spread
- End on the quietest picture, not the resolution; the resolution can be the spread before
- Record the reading at bedtime speed, slower than you think
How it works
1. Tell the story once Type it the way you tell it, refrain and all — or just the hero and the ending. Pick the 3–5 band; the word budget and the calm do the rest.
2. Read the storyboard first Claude writes a storyboard — the title, the cast with a visual identity card each, and every spread's words and picture brief — in about a minute, for ordinary conversation credits. Edit any line before a single picture is drawn.
3. Watch the pictures land Character sheets first, then every spread in the art style you picked, then the cover — each picture checked against the cast for likeness and style, redrawn once if it drifts. Your first spreads are free; after that each picture quotes its price in credits before it is painted.
4. Read it aloud, then print it Read it page by page in the studio or on its own free reading page, record your own voice for each spread (free) or narrate it, then order the 8.5×8.5 in colour hardcover — one copy or one for every grandparent.

Frequently Asked Questions
Can the book play my voice?
Yes. Record each spread in the browser — free, no credits — and the recording plays in the studio reader and on the book's public reading page, on any phone. Re-record any page any time.
Can Grandma record it from another country?
Yes, if she is on the book as an editor: she opens the Storybook tab, reads each spread into her browser, and the recordings are on the page the same evening.
How many spreads should a bedtime book have?
The 3–5 band defaults to twelve spreads (28 printed pages); ten is plenty for a toddler and sixteen is long. The stepper in the brief goes from 8 to 24.
Do I keep the rights?
Yes — authors keep ownership of their work. Print it, sell it from your free Infinite Library storefront (author-set print royalty, about 95% on ebooks, 80% on audiobooks), or keep it entirely private.
