Chess Analyzer — Analyze free

Adds an "Analyze free" button to finished chess.com games that opens a free Stockfish Game Review.

Review your chess.com games for free, with Stockfish running in your own browser. When a game ends, Chess Analyzer adds an Analyze free button right under chess.com's Game Review button — in the game-over window, in the sidebar, and next to every game in your archive. One click opens a full game review: • Every move labelled: Brilliant, Great, Best, Excellent, Good, Book, Inaccuracy, Mistake, Miss, Blunder • Accuracy for both players • Evaluation graph of the whole game — click it to jump to any move • The better move shown for every mistake, with an arrow on the board • Step through the game, or open any position in the full analyzer No account, no subscription, no limit on the number of reviews. The analysis is computed by Stockfish (WebAssembly) on your computer; your games are not uploaded anywhere. Privacy: the extension requests no browser permissions, collects no personal data and has no analytics. It reads only the game you choose to analyze.
