ScanChess
Turns a photographed scoresheet or board into PGN/FEN with a Stockfish review
Photograph a handwritten scoresheet or a board position; it reads the moves, checks them against chess rules, and exports PGN or FEN. A free Stockfish review then marks every inaccuracy, mistake and blunder and explains where the game turned, in plain language. Its own accuracy test reads 43 of 45 moves correctly on a real handwritten scoresheet. Scanning costs 1 credit per board or 2 per scoresheet, with 10 free credits on signup; the Stockfish review itself stays free.
