CrispChess

CrispChess shows you chess the way people play it, not only the way engines do. Everything runs on your device, without an account. HUMAN LENS See what players at your rating actually play in any position, how many of them would find the engine's move, and whether the position is a trap that catches most of them. After a game, compare your moves with players of your level instead of with a machine. SCAN A BOARD Choose a photo of a real chessboard or an image of a printed diagram, and CrispChess reconstructs the position so you can analyse it or play it out. Recognition runs on the device. YOUR GHOST Play against an opponent built from your own games: it plays your openings and otherwise plays like a player of your estimated rating. SPEAK YOUR MOVES Tap the microphone and say "knight to f3" or "castles", in English or German. The app matches what you said against the legal moves; no audio leaves your device. OPPONENTS FROM RESEARCH Beyond classic engines: human-like Maia bots, DeepMind's searchless transformers, a state-space network and chess-trained language models, each with a strength rating we measured by playing them against each other. PLAY AND LEARN • Adjustable built-in opponent and optional strong engines. • Rapid, blitz, classical and custom clocks; Chess960, King of the Hill, Three-check. • Tactical puzzles, drills, hints, opening explorer and full analysis. • Import, export and study PGN games and custom positions. PRIVATE BY DESIGN No account, advertising, analytics or tracking. Games and preferences stay on your device. Models and engines download only when you choose them. CrispChess is free and open source.
