Hi,

I'm big fan of crossword puzzles such as the New York Times daily crossword and I'd like to build my own crossword puzzle game.

Has anyone had any luck using AI or other tools to speed up the process of building crossword puzzles?

I've used the Phil crossword puzzle maker to export crossword patterns with a few clues and answers in JSON format. Then I've tried various prompts with Claude Sonnet 4 to fill out the rest of the puzzle but I haven't been able to produce a valid crossword puzzle with the across and down words intersecting properly.

Any advice on tools or prompting would be appreciated. Thanks!
