SmartKDP

This is the part no other tool I used would let me do.

You pick a trim size and a theme. Ask Book Studio for fifty puzzles. It lays them out and writes the answer keys.

Then you open one. Drag the grid. Change a color. Rewrite a single clue. Nothing regenerates. You are editing the actual puzzle, the same way you would edit anything else on the canvas.

That is the whole product, honestly. Generate and Place, then keep working.

I do not want two of my books sharing a grid. Amazon notices that before readers do.

Book Studio hashes each puzzle and checks it against this book and your other SmartKDP projects. Identical content gets flagged. The uniqueness certificate goes in the KDP upload package on Publisher and Studio.

Before export it runs the checks Amazon runs. Bleed, trim, spine, resolution. Print-ready means the file is actually ready. Passing preflight does not guarantee KDP will accept a book, but you find out here, not in a rejection email.

If you publish low-content, this is the part I wish existed when I started.

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.
