kdpbook.io

kdpbook.io is an AI book studio for Amazon Kindle Direct Publishing. You describe the book you want in a chat (or import your own manuscript) and kdpbook plans it, writes it, illustrates it with consistent characters and typesets every page. It then builds the exact files KDP asks for: the interior PDF, a full-wrap paperback or hardcover 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. It covers 36 book types in 8 families, 40 illustration styles (or your own), 34 KDP languages, 16 paperback trims and 5 hardcover trims. A page editor with live preview, AI rewrites, image redraws, a continuous KDP preflight and a 3D book preview let you fix anything before export. Free KDP calculators (spine width, cover size with template, printing cost, royalties) need no account. New accounts get 2,000 free credits (enough for a 32-page picture book); paid plans from $25/month export clean, commercially licensed files. Independent, not affiliated with Amazon.
