Free chess game analysis — that explains, not just evaluates
Most free analysis shows you a graph and a list of moves marked as mistakes. That tells you where you went wrong, not why — and nothing about the pattern behind it. RookMentor analyzes your whole recent archive at once: it finds every blunder, explains the principle you broke in plain language, and shows which mistakes keep repeating across your games. Free, no signup, works with chess.com and Lichess.

Generic advice ends here. Type your username and RookMentor reads your actual games — your blunder types, your clock, your openings, your tilt.
The method that actually works
1.Whole-archive analysis beats one-game analysis
A single game review shows one bad day. Analyzing your last 100+ games shows your patterns: the opening you always lose, the phase where your accuracy collapses, the moves you play too fast. Patterns are fixable; single games are just history.
2.Explanations, not evaluations
Knowing a move dropped 3 points doesn't teach anything. Knowing that 'you moved your queen onto a square the rook had covered the whole game — check the landing square before every check' does. Every critical moment gets a plain-language lesson.
3.Analysis that turns into training
Every blunder found becomes a drill: the position comes back and you must find the move you missed, on the board, until it sticks. That's the difference between reading about your mistakes and removing them.
Common questions
Is RookMentor's game analysis really free?
Yes — the fingerprint, deep scan, coach lessons, drills, and weekly plan are free with no signup. Analysis runs in your own browser, which is what keeps it free.
How is this different from chess.com's free Game Review?
Game Review covers one game and limits free deep reviews. RookMentor analyzes your whole recent archive at once, explains mistakes in plain language, and finds the recurring leaks a single-game review can't see.
Do I need to upload PGN files?
No. Type your chess.com or Lichess username and your public games import automatically in seconds.
