Move-by-move game review with accuracy scores
To review a chess game move by move, you replay each position through an engine and mark where the evaluation swings. Audit Chess does this automatically for every game in your Lichess or Chess.com history. Each game gets an accuracy score, an evaluation graph, and a label on every move - best, good, inaccuracy, mistake or blunder - computed with Stockfish in your browser. Instead of opening one game at a time, you see your accuracy trend across hundreds of games and can jump straight to the moments that cost you points. It is free, needs no account, and nothing is uploaded - the analysis runs on your device.
What the review shows
Every move is classified against the engine’s best line, so a single glance tells you where a game turned. The evaluation graph makes the swings visible: a cliff on the graph is the move that lost the game.
Because the whole history is analyzed together, your accuracy score becomes a trend you can actually track over weeks and openings, not a one-off number for a single game.
Why it beats reviewing one game at a time
Built-in analysis on Chess.com and Lichess is per-game. The patterns that hold you back - the same blunder in the same structure, the openings where your accuracy quietly drops - only show up across many games. Reviewing your whole history at once is how you find them.
