01 · Workflow

How AI Book Writer works, from idea to published book

Five stages, each a step in the same project. Let AI Book Writer lead any of them, or do them yourself.
  1. Describe the idea, set the basics and your style, build the cast, then outline every chapter.

    • A writing sample of up to 20,000 characters sets the voice
    • Characters with motivations, arcs and a note on how they speak
    • Outlines on Three-Act, Hero's Journey, Save the Cat or three other structures
  2. Chapters are drafted from their outline cards and the chapters before them, or you write them yourself.

    • Swift, Balanced or Literary, at 15, 20 or 30 credits a chapter
    • One chapter at a time, or all remaining chapters in one batch
    • Book two can remember book one (Pro)
  3. Edit and review

    AI book editor

    A whole-book review reads the full draft and returns a score, an editorial letter and pacing notes for each chapter.

    • Line edits you accept or reject one at a time
    • AI chat edits on the passage you choose
    • 15 credits per 1,000 words, once per book; re-runs are free
  4. Format and export

    Formatting and export

    Blurb, keywords, categories and a cover, then files a printer or a store will accept.

    • Print-ready PDF with trim sizes and themes, and EPUB (Pro)
    • DOCX from Plus, and Markdown on every plan
    • Preflight checks, and the spine width calculated for paperback covers
  5. Publish and market

    Book pages

    An author page and a page for each book, with free sample chapters and an email sign-up for more (Pro).

    • Social posts and email sequences built from the book
    • A press kit and review requests
    • Upload to the stores you choose, from your own accounts

02 · Book types

Three kinds of book, each with its own steps

AI Book Writer asks which kind when you start a book. It decides which steps you go through; everything else can change later.
  • Fiction

    Novels, novellas and short story collections, in any genre.

    • A story bible that keeps characters, places and rules straight
    • Six plot structures to outline on, from Three-Act to Kishōtenketsu
    • A mature-content switch for books that need one
    Writing fiction
  • Non-fiction

    Guides, how-to, business and self-help books, and course material.

    • Three whole-book structures and three chapter templates
    • Upload reference files and chapters cite them as [S1], [S2]
    • Sources are never invented
    Writing non-fiction
  • Visual books

    Pro plan

    Picture books, comics, manga, coloring books, alphabet books, bedtime stories and social stories.

    • Characters kept consistent with reference images
    • One art style per book, illustrated page by page
    • Single pages or spreads, and a print PDF with bleed
    Making visual books

03 · Your text

An AI book writer that never overwrites your text

AI work arrives as an offer. You decide what goes into the book, one passage at a time.
  • Drafts wait beside your version

    When a chapter already has your text, a new AI draft is kept next to it to compare, use or discard.

  • Edits stay where you asked

    A suggestion applies only to the exact passage it was made for. Tightening one paragraph never touches the next.

  • Every save is kept

    The version history holds each saved state of a chapter, so an earlier draft is always there to go back to.

You keep all rights to what you write with AI Book Writer, and you can export your work at any time.

04 · Audio and translation

One finished book, more ways to read it

Audiobooks and translation are part of the Pro plan. Both work from the book you already have in AI Book Writer, so there is nothing to paste or re-upload.

Audiobook Studio

Pro plan

Choose a narrator from 13 voices and give your characters voices of their own. Each chapter is recorded as its own MP3.

  • Re-record a single paragraph instead of the whole chapter
  • Loudness-levelled audio across voices and chapters
  • One MP3 with chapter markers, an M4B with chapters, and a zip of mastered 44.1 kHz / 192 kbps MP3s for distributors

1 credit per 12.5 characters of text, 20% more with character voices

About Audiobook Studio

Whole-book translation

Pro plan

Translate the whole book into any of 30+ languages in one pass, rather than pasting it in a chapter at a time.

  • Chapters, characters, outline and metadata, translated together
  • Saved as a new book, linked to the original
  • The original book is never changed

30 credits per book, plus 15 per chapter

Questions about AI Book Writer

Will the book sound like me?

It gets closest when it has something to match. Paste a writing sample of up to 20,000 characters, set the tone, point of view and tense, and give each character a note on how they speak. Read the first chapter, adjust the sample or settings if it needs it, and your own revisions do the rest.

Does the AI change what I've already written?

No. When a chapter already has your text, a new AI draft is kept beside it for you to compare, use or discard. Edit suggestions apply only to the exact passage they were made for, and every save is kept in the version history.

What can I do on the Free plan?

The Free plan includes 100 credits when you sign up, your first outline free, characters and a story bible, and a first chapter written by the AI. The standalone tools give 2 free runs an hour, and you can export everything you write as Markdown. Writing every chapter with AI starts on Plus.

Can I import a book I've already started?

Yes. Import a Word (.docx) manuscript of up to 200,000 words. Chapters are detected automatically and you check the split before anything is imported, and an optional AI pass fills in your characters and story bible. Importing is free.

Who owns what I write?

You do. You keep all rights to what you write with AI Book Writer. Markdown export is available on every plan, DOCX from Plus, and print-ready PDF and EPUB on Pro. If you publish through a store, check its current rules on AI-assisted books.

Which languages can I write in?

The AI Book Writer interface is in English, and books can be written in 30+ languages. On Pro, a finished book can be translated as a whole, including its chapters, characters, outline and metadata, into a new linked book. The original stays as it was.

How do credits work?

Every AI action has a price in credits, and you see it before anything runs. A plan's monthly credits are used first and expire at the end of the month; credits from sign-up, packs and referrals never expire. If a task fails, its credits are returned automatically. See pricing for every price.

Can I make picture books and comics?

Yes, on the Pro plan. Visual books are built page by page, with characters kept consistent through reference images and one art style per book. Pages can be single pages or spreads, and the book exports as a print PDF with bleed.

Start with the idea you already have

Write it down in a sentence or two, or bring the manuscript you have been working on. AI Book Writer is free to start, and the Free plan is enough to plan the book and read its first chapter.
