Your mistakes
repeat. We find
them first.
FireChess scans your Lichess & Chess.com games and isolates the recurring leaks costing you rating — then drills each one until it disappears from your games.
Scan your games in seconds
Pick a platform, enter your username, and get a full report with every mistake.
From raw games to a
fixable list, in three steps.
No setup, no imports, no PGN wrangling. Type your username and the pipeline handles the rest.
Connect your account
Paste your Lichess or Chess.com username. We pull your last 300 games automatically — blitz, rapid, or both.
Stockfish reads everything
Every move is evaluated at depth 22. We cluster the mistakes by opening, position type, and phase to find the patterns, not one-offs.
Drill the leaks away
Each leak becomes an interactive lesson built from your own games. Fix the top three and watch the next scan come back cleaner.
Not another game review.
A diagnosis.
Engines tell you a move was bad. FireChess tells you why you keep making it — across hundreds of games.
Opening leak detection
We track every opening position you reach more than twice and grade the moves you actually play — including the line where you win 30% when book says 55%.
Time trouble profiling
See exactly when your moves degrade — by clock position, not just move number.
Endgame conversion
How many winning endgames do you actually convert? Most players guess wrong by 40%.
Missed tactics, clustered
Your 91 missed tactics aren't 91 problems — they're usually 3 motifs you can't see.
AI coach summary
Plain-English read of your entire report. What to fix first, in order of rating impact.
Lessons built from your own games
Every leak spawns an interactive lesson using positions you reached — not generic puzzles. Replay the moment, find the move, understand the idea, then get quizzed on it in a fresh position. The drill adapts until the pattern sticks.
Rescan & compare
Scan again next month and diff the reports. Watch your leak count fall as rating climbs.

They found their leak.
Then they fixed it.
“My report said 34% of my losses came from one Caro-Kann sideline. I had no idea. Drilled it for two weeks, stopped playing it, and the rating graph turned around.”
Daniel K.
“I thought I was bad at endgames. Turns out I was winning 77% of won positions — my real problem was missing knight forks in the middlegame. Fixing the right thing matters.”
Sara M.
“The rescan diff is the addictive part. Every month I scan again and watch my leak count drop — 11 leaks in January, 4 in March. It's like a fitness tracker for chess.”
James T.

Quick answers.
Yes. A 300-game scan with the full report — leaks, tactics, endgames, AI coach — is free every month. Pro removes limits and adds progress tracking, nothing else is paywalled.
Lichess and Chess.com natively — just your username, no login. You can also upload a PGN directly if your games live somewhere else.
Per-game analysis tells you move 23 was a blunder. FireChess aggregates 300 games and tells you that 40% of your blunders are knight forks in the French — and then drills knight-fork patterns until you stop falling for them.
Roughly 800–2400. Below 800 the patterns are too noisy to cluster; above 2400 you'll want a human coach for nuance. Club players (1200–1800) see the biggest gains.
Your next 100 games
shouldn't repeat your last 100.
