Amazon's rules
What Amazon asks about AI
Amazon allows books made with AI on KDP, but it asks a question when you publish: does this book contain AI-generated content? Its content guidelines draw the line like this:
- AI-generated means text, images or translations created by an AI tool. Amazon says it still counts as AI-generated even if you edited it substantially afterwards. You must declare it.
- AI-assisted means you wrote it yourself and used AI to brainstorm, edit or improve it. You don't have to declare that.
- Covers and pictures count. An AI-made cover or interior illustration is AI-generated content too.
A book PromptBook drafts is AI-generated under that definition, however much you rewrite it, so tick the box. Declaring it isn't a penalty; it's the rule. Amazon has also capped how many new titles one account can publish in a day (three, as reported by the Authors Guild in 2023).
Read the rules in Amazon's own words: KDP content guidelines. We checked them on 7 November 2026; Amazon can change them at any time.
The files
What PromptBook gives you for KDP, and what it doesn't
| KDP needs | From PromptBook? | Notes |
|---|---|---|
| Kindle ebook (EPUB) | Yes | Reflowable EPUB with a table of contents. Upload it as your manuscript. |
| Paperback interior (PDF) | Yes | Print-ready interior at 5″ x 8″, 5.25″ x 8″, 5.5″ x 8.5″, 6″ x 9″, 7″ x 10″, 8.5″ x 11″, with front and back matter. |
| Paperback cover (full wrap) | Yes | Back, spine and front as one PDF, sized from your trim, paper and page count. Check it against KDP's cover calculator before you upload. |
| Word file (DOCX) | Yes | For an editor, a proofreader or your own layout software. |
| Description, keywords, categories | Suggestions | The marketing kit drafts a back-cover blurb, ten keywords and category ideas. Rewrite the blurb in your own words; it sells the book. |
| ISBN and pricing | No | You set these in KDP. Amazon offers a free ISBN for paperbacks. |
| Proof copy | No | Order one from KDP. Read it on paper before you click Publish. |
Quality
Before you press Publish
Readers can tell a book nobody read before it went on sale, and so can their reviews. The draft is the start of the job.
- Read every chapter. Out loud, if you can bear it. Cut the repeats, the throat-clearing and anything that sounds like a brochure.
- Check every fact. AI states wrong things confidently: dates, figures, quotes, laws. In non-fiction, verify each one or take it out. Our Search & Cite tool helps.
- Add what only you know. Your examples, your mistakes, your opinions. That is what makes a reader recommend it.
- Write your own blurb. Use the marketing kit's draft as a starting point, not the finished thing.
- Order a proof. Typos and layout slips are easier to spot on paper.
KDP Select
KDP Select and free samples
If you enrol the ebook in KDP Select (Kindle Unlimited), Amazon wants the ebook to be exclusive to Kindle while it's enrolled. If you want to share a sample anywhere else, check the current Select terms first.
That's why PromptBook never makes your book public on its own. Sharing is a private link you control, and if you choose to show your book in our gallery, you pick how much of it appears, with an option that keeps the public part to a sample.
Picture books
Publishing a children's picture book?
PromptBook's picture-book mode makes page-by-page stories at three reading levels in one illustration style, and exports them as a 10 × 8 inch landscape PDF. That is not one of KDP's paperback sizes (KDP paperbacks are at most 8.5 inches wide), so the PDF can't be uploaded to KDP as a paperback as it is. It's made for reading at home, home printing, print shops and photo-book services.
If you lay a picture book out for KDP yourself, from the Word file and in one of KDP's sizes, declare AI-generated pictures as well as text. Plan a picture book.

Questions
Can I publish a book written with AI on Amazon KDP?
Yes. Amazon accepts AI-generated books, but asks you to declare AI-generated text, images and translations when you publish a new book or republish an edited one. Books that read as low effort get poor reviews, so edit the draft properly before you upload it.
Do I have to tell Amazon if I edited the AI text heavily?
Yes. Amazon's guidelines say content created by an AI tool counts as AI-generated even if you applied substantial edits afterwards. Only content you wrote yourself and improved with AI counts as AI-assisted, which you don't have to declare.
Which files do I get for KDP?
A Kindle EPUB, a print-ready paperback interior PDF (5″ x 8″, 5.25″ x 8″, 5.5″ x 8.5″, 6″ x 9″, 7″ x 10″, 8.5″ x 11″), a full-wrap paperback cover PDF, and a Word file. You choose the ISBN, categories and price in KDP yourself.
Who owns a book written with PromptBook?
Under our terms the book you make is yours to publish and sell. Copyright in AI-generated text is unsettled in some countries, so if the book matters commercially, take advice and add plenty of your own writing.
How much does it cost?
The chapter plan on this page is free and needs no account. Free accounts can start 1 new book a month and keep 1 saved book, with EPUB, PDF and Word export. Basic ($9.99/month) allows 5 new books a month and Pro ($29.99/month) allows 10 new books. Deleting a book does not give the month's allowance back. Basic is $9.99 a month for 5 new books a month, and you can cancel any time.
How long a book can it write?
Short is 5 chapters (about 13,000 words) and takes roughly 30–60 minutes to write; medium is 10 chapters (about 27,000 words) and takes about 1–1½ hours. You can add chapters and expand any of them in the editor before you export.
