“Start this book” opens a new chat in kdpbook.io with the idea as your first message and its book type selected (you sign in or create a free account first). kdpbook replies with a plan (format, length, characters, art style) and shows a credit estimate before the book is generated. Planning-chat messages are metered: about 25 credits for the first one and about 8 after that. New accounts get 2,000 free credits once, with no card required.

3 ways to make an idea your own

  1. 01

    Name the solver, then the difficulty.

    Say who will do the puzzles (a 5-year-old, a grandparent who wants large print) and how hard they should get. The puzzles are generated and checked in code (every word placed, one solution per sudoku, one path through each maze), with the answers at the back.

  2. 02

    Let the theme do the work.

    A word search about something you know well (your hobby, your region, your trade) gets word lists nobody else would pick. List a few words you want in it when you start the chat.

  3. 03

    Plan it as a printed book.

    KDP’s guide to Kindle content quality lists puzzle books among the books not suited to Kindle, so kdpbook makes them as paperbacks or hardcovers. KDP generally doesn’t treat puzzle and activity books as low-content, because their pages aren’t repetitive.

Before you publish

  • Declare AI-generated content. KDP requires you to tell it about AI-generated text, images or translations when you publish a book, or edit and republish it. Content you wrote yourself and only edited with AI tools counts as AI-assisted and needs no disclosure. The listing sheet kdpbook exports suggests the answers from what was actually generated.
  • Make sure you own what is inside. KDP asks publishers to make sure their books don’t violate copyright, trademark, privacy, publicity or other rights, and it doesn’t allow undifferentiated versions of public-domain titles when a free version is already in its store. Leave out famous characters and brands, and add something new when you retell an old tale.
  • Keep the listing honest. KDP’s keyword rules exclude brands you aren’t authorized to use and the names of authors not associated with your book, and its content rules exclude descriptions that don’t match what is inside.
  • Read every page. KDP reviews every book itself, so no tool can promise that a book is accepted, sells or earns anything. You are the publisher: check the text, the pictures and the facts before you click Publish.

You can use, change and combine these ideas for your own books, with or without kdpbook. In the United States, copyright never protects an idea as such (17 U.S.C. § 102(b)); the Copyright Office explains that protection extends only to the original expression in a work, not to the idea underneath. This is general information, not legal advice.
