Comparison
Audit Chess vs Aimchess
Aimchess is a subscription analytics platform that tracks your games, gives you an Aimchess score, and recommends training modules. Audit Chess is free, needs no account, and runs entirely in your browser: it analyzes your whole Lichess or Chess.com history, ranks your openings by result, finds your repeated blunders, profiles your endgames and playstyle, and builds Stockfish-verified puzzles from your own mistakes. Both read your game history to find weaknesses. The difference is cost, access, and what they do with the data: Aimchess recommends curated training; Audit Chess turns your actual blunders into puzzles and lets you scout opponents.
Analytics vs puzzles from your own games
Aimchess gives you dashboards and trend charts for your game history, with an overall Aimchess score and recommended training modules. Audit Chess also gives you pattern analysis - worst openings, repeated mistakes, blown wins, endgame and playstyle profiles - but adds something Aimchess does not: puzzles built directly from your real blunders, verified by Stockfish. You drill the exact positions you got wrong, not a curated set.
Opponent scouting
Audit Chess includes opponent scouting: enter any Lichess or Chess.com username to see their weakest openings and the lines to prepare against them, matched to your own repertoire. Aimchess focuses on your own history and does not offer opponent analysis.
Cost and privacy
Aimchess is a paid subscription after a free trial. Audit Chess is completely free - there is no subscription, no free tier with paywalled features, and no account required. Analysis runs locally in your browser; nothing is sent to a server.
