kdpbook.io

kdpbook.io is an AI-powered book creation studio designed to simplify self-publishing through Amazon Kindle Direct Publishing (KDP). Whether you want to create a book from scratch or transform an existing manuscript into a professionally formatted publication, kdpbook.io provides an all-in-one workspace for planning, writing, illustrating, formatting, and preparing books for publication. Users can describe their book idea through an interactive chat or import manuscripts in Word, PDF, Markdown, or plain text formats. The platform helps plan book structures, generate written content, create illustrations with consistent characters, design covers, and typeset every page. It produces the essential files required for Amazon KDP, including print-ready interior PDFs, full-wrap paperback and hardcover cover PDFs calculated according to the final page count, Kindle eBooks in EPUB format (reflowable or fixed layout), and a complete listing sheet containing titles, descriptions, seven keywords, categories, and AI-disclosure answers. The platform supports 36 book types across eight families, including picture books, illustrated stories, novels, non-fiction, coloring books, activity and puzzle books, journals, and comics. Creators can choose from 61 illustration styles or use their own, publish in 34 KDP-supported book languages, and select from 16 paperback and 5 hardcover trim sizes. KDP formatting requirements, including trim sizes, margins, bleed, and spine calculations, are applied automatically, with built-in validation during editing. Additional features include a live page editor, AI-powered text rewriting, picture redrawing, character reference sheets, a 3D book preview, and a Book Assistant that helps users make changes across their projects. The platform also offers a free Chrome and Edge Publisher extension that helps fill Amazon KDP publishing drafts, while users retain control over reviewing and publishing their books. New users receive 2,000 free credits without requiring a payment card. Paid subscriptions provide watermark-free exports, private books, commercial licensing, and additional credits. With subscription plans starting at $25 per month, kdpbook.io makes AI-assisted self-publishing more accessible to independent authors, creators, educators, and entrepreneurs. The platform is developed in Paris by THE VIBECODING AGENCY and is not affiliated with Amazon.
