kdpbook.io is a browser-based book studio for self-publishers on Amazon KDP. You describe the book you want in a chat or upload your own manuscript, and it handles the writing, illustrations and page layout. It covers 36 book types and 61 art styles, and for fictional stories it uses character reference sheets so your hero looks the same on every page. When you’re done, you can export the interior PDF in 34 KDP languages, get the full-wrap cover, a Kindle EPUB and a listing sheet with keywords and AI-disclosure answers – all sized to KDP’s trim, margin, bleed and spine rules.
To get started, sign up, type a short prompt or import a Word, PDF, Markdown or text file, pick a book type and style, then tweak the result in the live preview before exporting. kdpbook.io offers a free plan with 2,000 credits at signup, which is roughly enough for one short watermarked picture book. Note that free exports can’t be sold, so you’ll need a paid plan for clean files and a commercial license. The tool is independent and not affiliated with Amazon, and KDP still requires you to disclose AI-generated content when you publish.
