ChessPivot Finds the Mistakes You Keep Repeating

Field notes

ChessPivot accepts connected online games as well as PGN files and Lichess studies, making it usable for players whose games are not stored on a single platform. Its stated workflow compares mistakes across a history of games, ranks patterns by their cost, and turns the resulting positions into exercises. The page also specifies imports of up to 1,000 over-the-board games and exposes a 0–100 Solidity Index for tracking cleaner play.
