Learn from
your Blunders.
Link your chess account and we'll sync your games every day, pinpoint the exact moves that cost you the point, and turn them into a training plan built from your actual blunders.
White to move
Everything you need to stop leaking rating.
Analysis, tactics, openings and coaching — built around your actual games, not somebody else's.
Blunder detection, move by move.
Every game you upload is run through the engine and graded. We surface the exact moves that tanked your eval — mistakes at a pawn, blunders at two — and why.
Puzzles from your losses
Tactics drills built from your own blunders — not a generic trainer.
Opening repertoire
Your lines, tracked game by game, ranked by win rate.
An AI coach that saw every game.
Ask why a move failed, what the threat was, or what to study next. The coach has context on your entire history — openings you're soft in, endgames you flub, the tactical patterns you keep missing.
Streaks that stick
Short daily training sessions, calibrated to your level.
We don't teach chess.
We fix the 3.8 pawns you keep giving away.
Most players plateau because their study is disconnected from their actual weaknesses. We close the loop.
Rating is the outcome. We measure the inputs.
Stop losing the same way twice.
Link your chess account or upload a PGN and we'll build a training plan from your own games.
