What a review tells you

Every move is scored against Stockfish 18's own choice, then labelled: best, excellent, good, inaccuracy, mistake, blunder, or brilliant. You get an accuracy figure and a performance rating for each side, an evaluation bar, and a graph you can click to jump straight to the moment the game swung.

Bring a game in three ways

Paste a PGN from any site, paste a Chess.com live, daily, or computer game link, or search a Chess.com username to pick from recent games. Typing rv in front of chess.com in a game URL opens the review directly.

Analysis that stays with you

Stockfish 18 is compiled to WebAssembly and runs inside this tab, so positions are never sent anywhere. Finished reviews are kept in your browser and restored when you reopen the same game.
