ChessCheatDetector.com
Analyze a chess game for signs of engine assistance. Paste a Chess.com link, paste a Lichess link, or upload a PGN.
Chess Cheat Detector analyzes the moves in a chess game using Stockfish and statistical models to identify unusually engine-like play. It does not claim to prove that a player cheated.
Results indicate statistical anomalies and should not be treated as proof of cheating.
