Analyze your chess games as a history, not one position at a time
Personal-history chess analysis compares the positions and choices that recur across your own games. It can show which openings, colours and time controls are associated with lower results, but it does not say whether a move is objectively best.

What the analysis measures
Imported games are grouped by colour, time control and opening. A win counts as one point, a draw as half a point and a loss as zero; each group is compared with the player’s overall score.
The game report asks a narrower question: did the player choose a move that has repeatedly scored worse than the move they usually play from the same position? Both choices need a meaningful history before the report says so.

What it does not measure
There is no chess engine in this analysis. It does not calculate centipawn loss, tactical accuracy or the objectively best move. That boundary matters: a historical pattern can identify a habit worth reviewing, while an engine answers a different question about position quality.
Frequently asked questions
Can I check a username before signing up?
Yes. The public preview reads up to 80 recent standard games and reports only patterns that clear the evidence threshold.
Is this Stockfish analysis?
No. The product compares your own choices and results; it does not run an engine or grade move quality.
Which chess sites can I import from?
The current importer supports public Chess.com and Lichess game histories.
