Statmate: chess analytics for Chess.com and Lichess

Statmate reads your public game history from Chess.com or Lichess and turns it into a full report on how you actually play. There is no account needed to look around, and nothing to install: type a username and the scan runs in your browser.

What it shows you

Game analysis. Stockfish 18 reviews any game move by move and labels each one, from Book and Best through Inaccuracy, Mistake and Blunder, up to Brilliant and the rarer Spectacular and Legendary tiers. Free accounts run the engine in the browser; premium runs the full engine on a dedicated server.
Accuracy over time. Your accuracy per game, per opening and per time control, with the trend across thousands of games rather than a single result.
Opening Lab. Which openings you score with, which ones quietly cost you rating, and how deep your theory actually holds up.
Rating history. Bullet, blitz and rapid on one graph, with peaks, troughs and best streaks.
Rival tracker and geography. Head to head records against everyone you have met, and a world map of the countries you play.
Insights. Time of day, day of week and session length, plus where your results drop off in long sessions.
Caissa, the AI coach. A coach that has read your own games and answers questions about them (premium).

Chess articles: writing on move classifications, opening leaks, rating graphs, when you play your best chess, and comparing players fairly.
How it works: where the data comes from and what the engine does with it.
Sample report: a full Statmate report, no username needed.
