AI chess analysis

ChessMoves AI analyses whole games and single positions. The engine measures every move; the explanations say what it means for you.

Game analysis

Every move of a game is checked by Stockfish, and the inaccuracies, mistakes and blunders are marked by how much each one changed the evaluation. You get your accuracy, the moments where the game turned, and the better moves you missed, with the engine line behind each one.

Natural-language explanations

The AI chess coach explains the key moments in plain words: the threat you missed, the plan behind the better move, the tactic that was there. Explanations come from the engine's findings, and the moves they mention are checked against the position.

Mistakes, tactical opportunities and improvement insights

Missed tactics and the theme behind them (forks, pins, hanging pieces and more).
Accuracy by game phase, so you can see whether the opening, middlegame or endgame costs you most.
Across games: the themes that repeat, and a training pack built from them.

Position analysis on the analysis board

Set up any position or paste a FEN or PGN on the analysis board, and Stockfish analyses it in your browser. Add notes, variations and arrows, file your work as studies, and share a position or a game with a link. The master games database shows what strong players chose in the same opening: see chess opening preparation.
