What we do
ChessAnalyzer helps players review completed chess games from Chess.com, Lichess, or a pasted PGN. The tool uses Stockfish analysis to surface accuracy, evaluation changes, move grades, mistakes, blunders, and stronger alternatives.
Our aim is practical learning: help you identify the decisions that changed a game, then understand the ideas behind a stronger move.
How the analyzer works
Chess analysis is designed for post-game review. Your game is loaded in your browser and Stockfish evaluates positions to provide a clear move-by-move report. It is not intended for live-game assistance.
Our publishing standards
Our guides are written to explain chess concepts clearly for players at different levels. We update pages when product behaviour, policies, or material information changes.
