Analyze your Lichess games and find your weaknesses

Type your Lichess username and we check your recent games with Stockfish, in your browser. You see the mistakes you make again and again, and get puzzles from your own games plus the lessons that fix them.

How it works

  1. 1We download your recent public games from the Lichess API (no login, no access to your account).
  2. 2Stockfish, running on your device, evaluates each of your moves and flags the ones that lose a lot of value.
  3. 3Every flagged move is classified: a hanging piece, a missed fork or pin, a missed mate, a king left in danger, a slip in the endgame.
  4. 4The report ranks the three patterns you repeat most, shows a real example from your games, and builds practice puzzles from those positions.
  5. 5Everything stays in your browser; a free account only adds syncing across devices.

Where to find your Lichess username

  • It's in your profile address: lichess.org/@/your-name.
  • Paste just the name, or the whole profile link: both work.
  • If your account is closed or your games are private, the analysis can't read them.

FAQ

Does Lichess already have analysis?add

Lichess analyses one game at a time. This looks across your recent games to find the mistakes you keep making, then gives you puzzles and lessons for them.

Do I need to log in to Lichess?add

No. Only your public games are read, through the official Lichess API.

Which games are included?add

Your most recent finished standard games: rapid, blitz, classical and correspondence. Variants like Chess960 are skipped.

I play on Chess.com too. Can I analyse those?add

Yes: use the Chess.com version of this tool. The report is the same, it just reads your Chess.com games.
