I got tired of puzzle generators that turn the book into a picture

If you publish puzzle books on KDP, you know the moment. The generator finishes. One grid is wrong. And there is nothing you can do, because what came out is not a puzzle anymore. It is a PDF.

The other option is Canva. Real editor. Knows nothing about trim, bleed, or spine width.

I built Book Studio for that gap. Word search, crossword, sudoku, maze, scramble, and a lot more. Every puzzle stays a live object on the page. You generate it, place it, then restyle it. Title, grid, word list, clues. Still editable at export.

Free calculators stay free. Book Studio is the part a calculator cannot do.
