kdpbook.io - Lovable for books: chat your idea, get a KDP-ready book

Hi Product Hunt, I'm Arsène, a solo founder in Paris. kdpbook came out of vibe coding (my company is even called The Vibecoding Agency). You describe an app, you get an app. At some point the obvious question came up: if you can describe an app and get it, why not a book? You describe the book in a chat, or import your own manuscript. kdpbook plans it, writes it, illustrates it and typesets every page, then exports what Amazon KDP asks for: the interior PDF, a full-wrap cover PDF, a Kindle EPUB and a listing sheet. 36 book types, from picture books and coloring books to journals and novels. What was hard: cover math first. The spine width depends on the final page count, so the full-wrap cover has to be resized every time the book changes, with bleed on every edge. Then keeping a character the same across a whole picture book: my answer is a reference sheet reused for every illustration. And typesetting that respects KDP's margins for each trim size. Honest limits: KDP requires you to disclose AI-generated text and images (the listing sheet includes those answers). Free-plan exports carry a "kdpbook.io preview" watermark and are not for sale. You get 2,000 free credits at signup, no card, enough for a 32-page picture book at default settings. One question for you: what would you need to see in a book made this way before you'd put your name on it?
