# kdpbook.io

> kdpbook.io is an AI book studio for Amazon Kindle Direct Publishing (KDP). You describe a book in one sentence, or import your own manuscript, and it writes, illustrates and typesets the book, then exports the files KDP asks for: the interior PDF, the full-wrap cover PDF, a Kindle eBook (EPUB) and a listing sheet (title, description, 7 keywords, categories, AI-disclosure answers). KDP's print rules (trim size, margins, bleed, spine, page limits, barcode area) are applied by code from a rulebook checked against KDP Help on 2026-09-26. kdpbook.io is independent and not affiliated with Amazon.

Key facts:
- Book types: 36 in 8 families (picture books, illustrated stories, novels & chapter books, non-fiction & guides, coloring books, activity & puzzles, journals & notebooks, comics & graphic novels).
- Illustration styles: 40 in 9 families, or a custom style described in words or from a reference image. Main characters get reference sheets reused on every illustration for consistency.
- Formats: paperback (16 standard trims + custom), hardcover (5 trims: 5.5 × 8.5, 6 × 9, 6.14 × 9.21, 7 × 10, 8.25 × 11 in), Kindle eBook (reflowable or fixed layout). Coloring, puzzle, activity and journal types are print only because KDP lists them as unsuited to Kindle.
- Editing: page editor with live preview, AI rewrites, image redraws, continuous KDP preflight, and a 3D book preview.
- Pricing: credits (1 credit ≈ $0.01 at the Starter rate). 2,000 free credits once at signup, no card required. Plans: Starter $25/month (2,500 credits/month); Author $49/month (5,500 credits/month); Studio $99/month (12,000 credits/month). Yearly billing costs 10 months. Credit packs for subscribers.
- Estimates (default settings): picture book 32 pages ≈ 1,624 credits; kids' coloring book 106 pages ≈ 1,803 credits; puzzle book 108 pages ≈ 460 credits; guided journal 120 pages ≈ 1,491 credits; non-fiction guide 192 pages ≈ 2,931 credits; novel 336 pages ≈ 5,377 credits. The estimate is held at launch; only what is produced is charged and the rest is released.
- Licensing: paid plans include a commercial license and watermark-free exports. Free-plan exports carry a "kdpbook.io preview" watermark, are not for sale, and free books are public in the community library.
- "Lovable for books" / vibe publishing: Vibe publishing is making a complete, publishable book by describing it in plain language to an AI studio that plans, writes, illustrates and typesets it, the way vibe-coding tools such as Lovable or Bolt turn a description into a working app. kdpbook.io is a vibe-publishing studio for Amazon KDP: you describe the book in a chat (or import a manuscript) and get the interior PDF, the full-wrap cover PDF, a Kindle EPUB and a listing sheet (title, description, 7 keywords, categories and AI-disclosure answers). Lovable, Bolt and v0 are named only as an analogy; kdpbook.io is not affiliated with them. Details: https://kdpbook.io/vibe-publishing.
- AI disclosure: KDP requires publishers to declare AI-generated content (text, images or translations) when they publish or republish a book, even after substantial edits; content you created yourself and only edited, refined or error-checked with AI tools is AI-assisted and needs no disclosure (https://kdp.amazon.com/en_US/help/topic/G200672390, checked 2026-09-28). The text kdpbook.io writes and the images it draws, cover art included, are AI-generated; a manuscript you wrote yourself and import stays your own text. The listing sheet pre-fills the disclosure answers from what was actually generated. kdpbook.io does not guarantee that KDP accepts a book.
- Company: kdpbook.io is built and run by its founder, Arsène Huot, in Paris, France, and published by THE VIBECODING AGENCY (SARL); launched September 2026. Press kit: https://kdpbook.io/press. Contact: contact@thevibecodingagency.fr.
