AI novel writer
kdpbook.io's AI novel writer turns a one-sentence idea or your own manuscript into a 336-page novel at 5.5 × 8.5 in: it writes and lays out the book, then exports the interior PDF, the full-wrap cover PDF, a Kindle EPUB and a listing sheet for KDP. The default book costs about 5,377 credits (≈ $54).
Adult fiction in any genre (romance, thriller, fantasy, sci-fi, literary), 60k–110k words, formatted for paperback, hardcover and Kindle.
To sell the book, export it on a paid plan: every plan from $25/month (Starter, 2,500 credits a month) gives watermark-free files with a commercial license, and kdpbook.io takes no royalty. See plans

How a novel is laid out
30 to 60 chapters of 1,500 to 3,500 words, set in 10.5 to 12 pt serif with running heads. Genre sets tone and pacing (romance: dual POV and heat level; thriller: short chapters and cliffhangers).
The default voice is suspenseful: tension and page-turning pace. You can change the audience, tone and length in the Story step.
Three novel ideas to start from
Each one opens a new novel with the idea already written in. Change anything before a page is made.
The numbers KDP will check
These are the specs of the default novel, computed from our KDP rulebook: the same code that lays out your pages and sizes your cover. Change the trim, paper or page count and every number updates.

Styles that suit a novel
Audiences
Fonts, type size, sentence length and vocabulary follow the audience you pick.
Before you publish
- KDP asks you to declare AI-generated text when you publish; a manuscript you wrote yourself and import stays your own text. The export sheet tells you exactly what to answer.
- Choosing the large-print audience sets the body text at 16 pt or more, which roughly doubles the page count.
Common KDP rejections for this type
The KDP messages that apply to a novel, and what usually causes them. The KDP preflight in the editor checks for each of them before you export.
- Content outside the margins
A text box was moved or enlarged near the edge, the page count grew past a gutter step (150, 300, 500 pages), or a long word or web address runs into the margin.
- Inside margin (gutter) too small
The book crossed a page-count step after the margins were set.
- Content review (quality, rights, AI)
Reviewers flag books that feel thin, repetitive, or too close to other books.

Novel questions
What trim size is best for a novel on KDP?
kdpbook.io starts novels at 5.5 × 8.5 in on black & white interior with cream paper. You can switch to 5 × 8 in, 5.25 × 8 in, 5.06 × 7.81 in, 6 × 9 in and more; the layout and cover are recalculated for the new size.
How many pages should a novel have?
Our novel template runs 200–700 pages and defaults to 336. For this ink and trim, KDP accepts 24–776 pages. KDP counts every page, including front matter and blank pages, and rounds odd counts up to an even number.
What does formatting a novel for KDP involve?
A trim size (5.5 × 8.5 in by default, on black & white interior with cream paper), margins that grow with the page count (0.625 in on the spine side at 336 pages), every font embedded in the PDF, and a cover whose spine matches the final page count (0.84 in here). kdpbook applies those rules in code and runs a KDP preflight before export.
Can I publish a novel as a Kindle eBook?
Yes. Reflowable EPUB: text adapts to the reader's screen and font size. It is exported from the same project as the paperback and hardcover.
Can I make a novel in Spanish, German or French?
Yes. kdpbook.io can make a novel in 34 languages that KDP publishes, including English, Spanish, German, French, Italian, Portuguese and Dutch. On KDP, Polish, Ukrainian and Yiddish are print only, and Arabic, Hindi, Chinese (Traditional), Tamil, Marathi, Gujarati and Malayalam are eBook only. The kdpbook.io editor is in English, and the Book assistant replies in English, French, Spanish, German, Italian or Portuguese, following the language you write in.
How many credits does a novel cost on kdpbook.io?
The default novel (336 pages, about 80,000 words) is estimated at 5,377 credits, about $54. You see the exact estimate before you launch, only what is produced is charged, and the rest of the hold goes back to your balance.
Can I sell a novel made with kdpbook.io on Amazon?
Yes, on a paid plan (from $25/month): its files have no watermark and come with a commercial license, while free-plan files are a watermarked preview. Plans: kdpbook.io/pricing.
Can a novel use KDP Expanded Distribution?
Eligible for this trim and paper. The default paperback can be enrolled in Expanded Distribution: it offers the paperback to bookstores and libraries outside Amazon at a 40% royalty.
Will my manuscript be changed?
No. Import it as a Word file (.docx or .doc), a PDF, Markdown or plain text and the text is printed word for word: kdpbook adds the table of contents, chapter openers and running heads, sets the pages at 5.5 × 8.5 in and builds the cover and Kindle EPUB around it. The text only changes if you edit it or ask for a rewrite.
Do I have to tell Amazon the book was made with AI?
Yes, for AI-generated content. KDP asks you to declare AI-generated text, images or translations when you publish or republish a book, even if you edited them substantially. Text kdpbook writes is AI-generated, while a manuscript you wrote yourself and import stays your own text. The cover art kdpbook paints, and any illustrations it paints inside the book, are AI-generated images. The export sheet pre-fills the answers from what was actually generated for your book.
