What it does
- Makes a whole book from a sentence. You describe the book in a chat, or import your own manuscript, and kdpbook plans it, writes it, illustrates it and typesets every page.
- Covers 36 book types in 8 families: picture books, illustrated stories, novels & chapter books, non-fiction & guides, coloring books, activity & puzzles, journals & notebooks and comics & graphic novels. See every book type.
- Keeps characters consistent. Main characters get reference sheets that are reused on every illustration, in one of 40 illustration styles or a custom style described in words or from a reference image.
- Applies KDP’s print rules by code: trim size, margins, bleed, spine width, barcode area and page limits, with a continuous KDP preflight check.
- Exports the files KDP asks for: the interior PDF, a full-wrap cover PDF sized from the final page count, a Kindle eBook (EPUB, reflowable or fixed layout) and a listing sheet with title, description, 7 keywords, categories and AI-disclosure answers.
- Lets you change anything in a page editor with live preview, AI rewrites, image redraws and a 3D book preview. Free KDP calculators (spine width, cover size, printing cost and royalty) work without an account.
The 70-second demo
A 70-second walkthrough of kdpbook.io, the AI book studio for Amazon KDP: a book described in one sentence is planned, written and illustrated with the same characters on every page, checked against KDP’s print rules, previewed in 3D and exported as the files KDP asks for. The video is edited for length.
What the demo shows
- The problem: KDP’s rulebook for margins and spine width, and an upload that gets rejected.
- Describing a book in one sentence in kdpbook.io.
- The book being planned, written, cast on character sheets and painted.
- 40 illustration styles, with the same hero from the cover to the last page.
- Bleed, trim and the KDP preflight check.
- The 3D preview: pick a format, read the book page by page, turn it to see the cover, spine and back.
- The export: the paperback interior and cover, the Kindle eBook and cover, and the listing sheet.
- Changing anything by asking in the chat, including pasting a message received from Amazon KDP.

Story angle: vibe publishing
Lovable describes vibe coding as development where you “describe what you want to build in plain language” and AI turns it into working software (lovable.dev, checked September 28, 2026 (opens in a new tab)). kdpbook.io applies the same idea to books, which we call vibe publishing: you describe the book you want in plain words and get a finished book in KDP’s formats. Think Lovable, but for books. kdpbook.io is not affiliated with Lovable.
