Comparison
Audit Chess vs Lichess analysis
Lichess analysis is excellent and free: per-game computer analysis, an opening explorer, and study tools. Audit Chess is not a replacement for it - it is a layer on top of your whole history. Lichess analyzes the game you are looking at; Audit Chess analyzes all of them together and reports the patterns: your worst openings by result, the mistakes you repeat, the winning positions you blow, your endgame and playstyle profiles, and puzzles built from your own blunders. It also scouts opponents. Both are free and both respect you - Audit Chess runs entirely in your browser with no account. Use Lichess to study a position deeply; use Audit Chess to know which positions and openings deserve that study.
What Audit Chess adds
Lichess gives you world-class per-game tools. Audit Chess adds the cross-game view: everything ranked by your real results, repeated-mistake detection, blown-win detection, an endgame profile, a playstyle profile, and puzzles generated from your own games and verified by Stockfish.
It also works across both platforms, so if you play on Lichess and Chess.com you can see one combined picture per platform.
