Free chess analysis — questions

Yes. Importing your games, running full Stockfish 18 analysis, seeing your style radar, training puzzles from your mistakes, and getting 1 AI-coached game is free. No card required.

Do I need to create an account?

No. Enter your Chess.com or Lichess username and start. You can create an account later if you want to keep your history across devices.
