POCKET GM AI CHESS COACH, GAME REVIEW & FOUR TRAINING LABS FOR iOS & MAC
ChessMinds
Traditional chess engines spit out cold scores like -1.8 or slap you with a red blunder icon without explaining why. ChessMinds reviews your games like your personal sea-otter Grandmaster Coach Otto—explaining which squares were weakened, what tactical threats your opponent prepared, and turning post-game diagnosis into deliberate practice across four immersive offline labs.
