One studio, from blank page to bookshelf.
Write it, illustrate it, cover it, narrate it, prove it will print, and write the listing that sells it. Everything below is the real product — these are screenshots, not mockups.
Write it.
A real word processor on the real page, and an AI that never once writes over your words.
A word processor, on your book’s true page.
Headings, quotes, lists, tables, page breaks — on a sheet with your book’s true trim width and print margins. Front matter and back matter are pages in the same list as your chapters, so a dedication is written where it prints.
When a passage needs lifting, select it and ✦ Ask about this: the assistant opens beside the page with the passage quoted, and its rewrite comes back as a change you review, apply or discard. Nothing is ever overwritten silently.
An assistant that has read the whole book.
Ask it anything about your book — a continuity question, a chapter that drags, a name you are not sure you used before. It reads the outline, the codex and the chapters before it answers.
When it suggests a change, the change is a card: review it, apply it or discard it. Every turn shows its credit ceiling before you send, and in a layout book the same assistant checks pages, tidies type and reviews your templates.
One idea in. A whole arc out.
Your premise becomes a coherent chapter-by-chapter arc — or you lay it out yourself. Rename, reorder, add sub-points, regenerate until the shape feels right.
Then it stays coherent: every AI call carries the full outline and the story so far, so chapters written weeks apart still read as one book.
The unglamorous half that makes a long manuscript survivable.
A story foundation
Before chapter one: the kind of story, its structure — three-act, Save the Cat, romance beats, a mystery’s clues, kishōtenketsu — the central question, and what your protagonist wants, needs and wrongly believes. The outline and every chapter are written to it.
Scene cards
Each chapter carries its turns — what changes, who wants what, what it costs — so a drafted chapter does the job the outline gave it.
Story codex
Pin characters, places and facts as canon. Every AI call — outline, chapter, whole-book draft — treats it as immutable truth.
Consistency check
One click audits the manuscript against your codex and flags contradictions with the exact quote, the chapter and a fix.
Deep research
Give it a topic; it researches the live web, files findings into your codex with real sources, and grounds later chapters in them.
Import your manuscript
Bring an existing draft in from DOCX, EPUB, Markdown and more — chapters detected, formatting preserved.
Version history
Every chapter keeps restore points: before each AI accept, each find-and-replace, and rolling checkpoints as you write.
Draft the whole book
Auto-draft writes every empty chapter in order on our servers, each followed by a polish pass. Close the tab; come back to a first draft.
Make it.
13 kinds of book — because a coloring book, a photo book and a puzzle book break every rule a novel lives by.
For these, the page is the unit — not the chapter.
The page count is exact rather than estimated, so they get their own editor — a real page designer — with the trim, paper, ink and bleed each kind actually prints on, set from the start.
Novel or non-fiction
Flowing chapters, typeset to your trim — the manuscript pipeline.
Coloring book
Full-page line art, one design per sheet.
Children's picture book
Full-colour illustrations with a line or two of story, read as spreads.
Planner / journal
Undated spreads, grids and ruled pages — built from templates, not AI.
Recipe book
A photo, an ingredients column and a method that has to fit the page.
Photo book
Photography, art, travel and gift books — picture-led, in colour.
Word search puzzles
A generated letter grid and its word bank on every page.
Sudoku puzzles
A generated grid on every page — 4×4 up to 16×16 — with its answer at the back.
Maze puzzles
A generated maze on every page — one or up to six a page — with its way through at the back.
Word scramble puzzles
Themed words with their letters jumbled on every page, the answers at the back.
Cryptogram puzzles
A famous quotation in a letter-for-letter code on every page, the decoded line at the back.
Crossword puzzles
Themed words and their clues fitted into a numbered grid on every page, the filled grid at the back.
Activity book
Word searches, sudoku, mazes, crosswords, word scrambles, cryptograms and coloring pages, each in a section of its own with its answers at the back.
Describe each page. Watch it get drawn.
Say what each page should show; the AI illustrates it. Line art comes out flattened to pure black and white, because the antialiased grey every image model produces falls below the minimum ink coverage a printer will reproduce — which is why lines come out broken.
Preflight runs as you work: art that misses the bleed, type too small to read, colour in a black-ink interior, grey too light to print at all.
Design one page. Every page follows.
Ruled lines, dot grids, month and week spreads, habit trackers, meal plans, ledgers, recipe and photo-book layouts — generated to your page, not pasted in, so writing lines follow the gutter and a spread’s two halves mirror correctly across the fold.
Adjust the template’s own settings, then stamp it across the book at once.
A bookstore cover, on your printer’s exact wrap.
Start from a genre template, then design front, spine and back on the wraparound canvas — spine width computed from your real page count. Free-form text, shapes and images with snap guides, plus AI cover art from a one-line prompt.
The trim, paper and page count come from the book itself, so the wrap is always the one your interior prints at. Paperback or hardcover is one switch — and where a printer doesn’t offer your trim in hardcover, it says so instead of quietly changing it.
Prove it prints.
Four printers and five ebook stores, each with its own rules — checked separately, before you upload anything.
Every check a printer would fail you for.
Pick where you’re publishing — the printers Amazon KDP, IngramSpark, B&N Press and Lulu, and the ebook stores Kindle, Apple Books, Kobo, Google Play and Draft2Digital — and Release checks your book against each one separately. The printers disagree enough that the same manuscript legitimately has a different page count and a different spine on two of them.
It measures, it never estimates
Nothing that depends on your page count runs off a word-count guess. The interior is rendered and counted first — a spine built on an estimate is a cover the printer rejects.
Every number carries its source
Published spine calculators disagree by enough to fail a cover, so each figure says where it came from and when it was checked. Where a platform keeps its formula private, the board asks you to read one number off their calculator rather than quietly inventing it.
Approval expires when the book changes
Add a chapter after signing a cover off and the tick comes back off, because it was approved at a different length. A tick that survives a page-count change is a lie.
When every target passes, one button builds the lot: each platform’s interior and cover wrap, rendered to its own rules, zipped with a spec sheet. You still upload to the stores yourself — we make the files that pass.
Every format your book needs, from one place.
One manuscript, every deliverable: the print-ready interior PDF, a reflowable EPUB 3, an editable DOCX for your editor, and the cover files each store wants — proofed first as the exact pages that will print.
The EPUB is run through EPUBCheck, the validator the stores use. Apple Books and Google Play refuse a file that fails it, so for those two an error stops the release instead of reaching their inbox.
Set the format once. Write on the true page.
Choose your printer and trim up front. Margins, gutters and spine width follow that platform’s rules automatically, and from then on what you see in the editor is what prints.
Then sell it.
Files don’t sell books; listings do. And an audiobook you can correct one sentence at a time.
An audiobook you can fix one line at a time.
Your book is cut into passages, each rendered and priced on its own. Fix a typo on page 200 and only that passage re-narrates — the rest is already made and stays free. It’s punch-and-roll, the way real narrators work.
Direct the performance in plain words, give a character their own voice, spell a name the way it should sound. Then the studio transcribes its own output back and flags any passage that drifted from your text.
Worth knowing up front: ACX and Audible do not accept AI narration. These files are for Google Play, Kobo, aggregators such as PublishDrive and Author’s Republic, and your own store — and on Amazon, Virtual Voice on the eBook. Creator plan and up.
The part that actually sells the book.
Blurb, tagline, keywords, categories, author bio and social posts — written from your actual premise, codex and opening pages, then checked against each store’s real field limits, counting the way that store counts.
Your cover becomes a real three-dimensional book you can turn to any angle, on studio backdrops, at every size the stores and socials want.
There is deliberately nowhere to put a comparison title, a review quote or an award — a field that doesn’t exist can’t be invented, and inventing those is false advertising.
And the things that outlive any one book.
A character library
Your cast, with their portraits and their voices, kept once and brought into any book or series. A picture book’s pages are drawn from the character’s own reference picture, and the audiobook narrates them in their usual voice.
An art library
Every picture you generate or upload is kept, and can be placed again in any book. Nothing is deleted while a page, a cover or a character still uses it.
Series
Volumes share one canon. The second book’s codex starts from everything the first one established.
A shelf you can almost touch.
Every book autosaves to the cloud and stands on your shelf as a real 3D volume, built from your actual cover, with a spine that thickens as the manuscript grows. Hover one ↓
