No account needed

You keep making the same mistake.

Type your Chess.com or Lichess name. We find the moves that cost you in your own recent games and put you back in those positions, so you can play the move you missed.

  1. Your own recent games. We pull them from Chess.com or Lichess.
  2. The engine reads them while you wait. It only finds the mistakes.
  3. You play the move you missed.

Two games show you a mistake. A library of games shows you the mistake you keep making, and that is what an account is for. Why we built it this way.
