kdpbook.io pricing: pay for what gets generated.

Every book gets a credit estimate before you launch it. We hold that estimate (plus up to 5% headroom) while the book is made, charge what is actually produced, and release the rest automatically.

New accounts get 2,000 credits once, with no card required. That covers a complete 32-page picture book (about 1,614 credits). Free books carry a preview watermark and are shared in the community.

Yes. Subscribers can buy one-off credit packs at any time, with a discount on the Author and Studio plans. Packs are for subscribers only.

Editing text, fonts and layout by hand is free. An AI rewrite costs 12 credits per passage of about 350 words, and redrawing an illustration costs the same as drawing it the first time. The planning chat and the Book assistant are charged for the AI they really use (8 credits per cent of AI cost, shown under the message box): a planning-chat message is about 8 credits (the first one about 9), a Book-assistant message about 40. Small AI helpers such as title ideas or picture descriptions cost 1 to 2 credits; setting a book up in the steps instead of the chat is otherwise free. Exports and the KDP listing sheet are always included.

Yes, from the Starter plan up: paid plans include a commercial license and watermark-free exports. You must declare AI-generated content to KDP when you publish.

kdpbook.io doesn’t print, ship or sell books. Once you publish your book on Amazon KDP (publishing there is free), it is sold on Amazon like any other book, in print and as a Kindle eBook. Before you publish, KDP lets you order a proof copy to check it on paper; afterwards, author copies at printing cost. To sell it, export it on a paid plan: free-plan files carry a watermark and are not for sale. Books in the kdpbook.io community library can be read online for free.

kdpbook.io never publishes for you, but on a paid plan it can fill your KDP draft. kdpbook Publisher, our free extension for Chrome or Edge on a computer, works in your own signed-in KDP tab: it enters the book's details, categories, files and prices, then saves the draft. You review the draft and click Publish yourself, and KDP reviews every book. Without the extension, you upload the exported files to KDP by hand. How it works: kdpbook.io/kdp-extension.

kdpbook.io can make a book in 34 languages that KDP publishes, including English, Spanish, German, French, Italian, Portuguese and Dutch. On KDP, Polish, Ukrainian and Yiddish are print only, and Arabic, Hindi, Chinese (Traditional), Tamil, Marathi, Gujarati and Malayalam are eBook only. The kdpbook.io editor is in English, and the Book assistant replies in English, French, Spanish, German, Italian or Portuguese, following the language you write in.

Yes. You keep your plan until the end of the billing period, and the books you made stay in your account.

Yes. Files you exported while on a paid plan keep their commercial license after you cancel: you can keep selling the books you published with them, and upload those files to KDP again. Files exported after your plan ends, including with “Regenerate files”, carry the free plan’s watermark, so download each book’s final files before your billing period ends.

Not on our side beyond your credits. KDP sets two limits of its own on new titles: its help page currently states 2 new titles created and 2 submitted for publication per format each week (a draft counts when you first submit it), and KDP’s own pages decide when you reach one. Plan releases accordingly.
