Chessmonitor is a free web tool that pulls your game history from Lichess or Chess.com and generates detailed analytics about your play. Beyond basic win/draw/loss ratios, it tracks trends over time: how your accuracy is changing, which phases of the game are your weakest, performance by time control, results with specific openings, and how your rating has moved.

The dashboards are interactive and can be filtered by date range, time control, and color, making it easy to identify patterns and track the effect of deliberate changes to your study or playing habits. The tool also provides comparative statistics showing how specific metrics compare to other players at your rating level.

Chessmonitor is free and requires no account registration beyond entering your chess platform username. It is a useful complement to game review tools, shifting the focus from individual game analysis to longer-term statistical patterns.
