PolyMind Chess

ChatGPT plugin

Play. Compare. Understand.

View in ChatGPT directory

Play chess against OpenAI Decisions or JEV by TypeSafe, compare their choices on the same position, and learn with Léon. Stockfish calculates candidate moves; your chosen decision engine selects a move. Explore variations, review move history, take back a turn and export PGN. Developer details show measured model preferences and request data. Preferences are not winning chances, difficulty is qualitative, and coaching uses calculated facts. English interface. Hosted games expire after 24 hours without a game-changing action. Website accounts and voice features are separate. PolyMind Chess is an independent product.
