Why reviewing your games is the fastest way to improve
Below master level, nearly every lost game contains one clear moment where it turned — a threat missed, a piece left loose, a trade that helped the opponent. Playing more games repeats those mistakes; reviewing them removes them. Players who review every loss climb hundreds of points faster than players who only play.

Frequently asked questions
Is Chessiro's game review really free?
Yes — game reviews on Chessiro are free and unlimited. There is no one-review-per-day cap. Analysis should be free: reviewing your games is the single best way to improve, and we don't think it belongs behind a paywall.
How do I review a Chess.com game for free?
Export the game's PGN from Chess.com (Share > PGN, or connect your account to import games directly), paste it into Chessiro, and you get a full review: accuracy, every blunder and mistake marked, and a plain-English explanation of what went wrong at each turning point.
What does the free review include?
Stockfish engine analysis of every move, move classifications (brilliant, great, mistake, blunder), the game's turning points, plain-English explanations from the AI coach, and follow-up chat — you can ask why a move was bad and get an answer about your actual position.
Can I analyze Lichess games too?
Yes. Chessiro accepts PGN from any source — Lichess, Chess.com, over-the-board games you've transcribed, or games from any other app.
How is this different from Chess.com's game review?
Two ways: it's unlimited and free rather than capped per day, and the explanations are conversational — you can ask follow-up questions about any move and the AI coach answers based on your actual game, then turns your recurring mistakes into training positions.
Do I need an account to review a game?
You can start analyzing right away by pasting a PGN. A free account lets Chessiro track your games over time, spot your recurring mistake patterns, and build personalized training from them.
