Chess Coach: Free Game Review & Stockfish Analysis

Free chess game review with Stockfish: move badges, accuracy, best moves, your own variations and a blunder trainer.

Chess Coach is a free game review for your chess.com games, powered by Stockfish 19 running right in your browser. No subscription, no review limit, no account. GAME REVIEW, EVERY MOVE LABELLED • Chess.com-style move badges on the board: Book, Brilliant (!!), Great (!), Best, Excellent, Good, Inaccuracy (?!), Mistake (?), Blunder (??) • Accuracy for both players, using the Lichess accuracy formula (checked against chess.com's own numbers) • Eval bar, eval graph with mistake markers, and best-move arrows • The engine's best move and full line for every position • Opening book moves recognised from the Lichess opening list EXPLORE YOUR OWN VARIATIONS • Move pieces on the review board and Stockfish evaluates your line instantly • Promotion picker, take-backs, flip board • Keyboard: ← → to step, Home / End, F to flip TRAIN YOUR OWN BLUNDERS • Your mistakes and blunders become flashcards: find the move you missed • Spaced repetition (Leitner) brings each position back when it is due • "Import my last games" analyses your recent chess.com games in the background WHERE THE GAMES COME FROM • My games: your finished games from chess.com's public API • This tab: the chess.com game open in your current tab • PGN: paste any PGN, from any site • One click opens the game in Lichess analysis FAIR PLAY The engine never runs on a game you are still playing: your own games unlock only once chess.com lists them as finished. Live mode shows the engine only for other people's games. Using an engine during your own games breaks chess.com's rules. PRIVACY • Stockfish runs locally in your browser • Your settings, evaluations and flashcards stay in your browser's storage • Requests go only to chess.com's public API (your game list), Lichess cloud evaluation (opening positions) and Lichess import (when you click it) • No analytics, no tracking, no account Chess Coach is not affiliated with Chess.com or Lichess.
