Lichess's computer analysis marks inaccuracies, mistakes and blunders. Here every move gets a label, including Brilliant for a real sacrifice, Great for the only good move, Book for opening theory and Miss for a chance you let go, and an explanation in plain words: what a mistake allows, what was better and why. How each label is decided.
Each move's accuracy uses Lichess's own formula, and the game's score is fitted to Chess.com's reviews of real games. So a Lichess game can be compared with a Chess.com one, or with a friend who plays there.
Stockfish 19 runs on your device. The game is fetched from Lichess's public API and isn't stored, and the review never leaves your browser. Have a single position instead? Use the position analyzer.
