A chess analyzer that says it finds recurring mistakes in your Chess.com games and turns them into targeted puzzles.

Landing page captured for the 2026-09-30 issue.

For: Chess.com players seeking recurring-blunder practice
Worth noticing: The page ranks mistakes by games they cost and shows sample conversion rates for four player profiles.

Field notes

The homepage presents a username field and describes an analysis pipeline based on games from the Chess.com public API and Stockfish 19. Its sample profiles show game counts, ratings, and a leading weakness, including conversion rates for winning positions. The site also says new games sync automatically and are analysed within minutes; the supplied page does not demonstrate that workflow in use.
