Frequently asked questions

Are the phrases well known or made up?+

The AI writes proverbs and short phrases on the book theme, and you read each one before exporting: replace the ones you do not like.

Does it come out on Kindle too?+

No. It is a book to write or color in by hand, so it comes out as a KDP paperback only.

How much does it cost?+

You pay once per book, with no monthly fee, and the package does not expire. The account is free: you can create the book and see the path before paying.
