Your chess
has leaks.

GigaChess reads every game on your account, finds the mistakes you keep making, ranks them by how many games they cost you, and turns your own blunders into puzzles. It will not ask about your rating. It will ask about move 23.

Built for the 2am blitz session you swore was your last.

01

The leak report

Why you lose, ranked: missed threats, thrown-away wins, clock trouble, tilt, weak openings. Numbers, not vibes.

02

Your blunders, as puzzles

Every real mistake becomes a puzzle from your own games, with spaced repetition until the pattern finally sticks.

03

Always watching

New games sync on their own and get analysed within minutes. Every game gets an evaluation curve showing exactly where it turned.
