Common questions
Will it spoil the answers?
No. CrosswordAlly shows you which squares don't match — never the correct letters — unless you explicitly choose to reveal a letter or an answer.
Which crosswords does it work with?
Currently the New York Times daily crossword. You pick the puzzle's publication date before uploading.
Do you keep my screenshot?
No. Your screenshot is used to check your puzzle and is not kept longer than necessary.
More ways to get crossword help
CrosswordAlly is built around one idea: you don’t have to spoil the whole puzzle just because something is wrong. The screenshot checker compares your grid against the published solution and flags only the squares that don’t match.
Prefer to work from a clue instead? The clue lookup searches our puzzle collection and lets you reveal a letter or the answer only when you choose. Learn more about getting crossword help, how the screenshot solver works, or get help with the NYT crossword.
