A chess coach built from your own games
Most training products sell you a pile of puzzles and hope. This one reads your real games, finds where you’re actually losing points, and builds a personalized plan to fix it — then measures whether your real-game mistakes drop. The tooling that used to cost a coach’s hourly rate, in a browser tab.
Play and review a few games to seed it. Your Skill Profile comes with Standard; the full coaching plan is a Premium feature — see plans.
It trains your mistakes, not random puzzles
The plan is mined from your reviewed games. The patterns you actually miss become drills — and the scheduling unit is the pattern, so when a fork weakness comes due you get a fresh fork position you’ve never seen, training retrieval instead of recognition.
Spaced repetition, tuned to ~85% success
Weaknesses resurface on a forgetting curve, and difficulty self-tunes toward the ~85% success band where learning is fastest (Wilson et al., 2019). No farming a vanity rating on puzzles three classes too easy for you.
A curriculum, not a puzzle list
Depending on your rating and your gaps, the plan mixes tactics, guess-the-move on your own games, “convert this won position” play-outs against a bot, rating-banded endgames drilled to mastery, and a composure habit. A 900 and an 1800 get structurally different plans.
Ranked against your actual level
Your Skill Profile ranks more than a dozen parts of your game against real players at your rating: overall move quality first, then broken out by phase (opening / middlegame / endgame), by situation (converting wins, defending losses, sharp tactical positions), and by composure. The plan targets the dimension where you’re furthest behind.
It reads your tilt
Composure is the signal almost nobody else surfaces, ranked vs your level like everything else: whether your play holds up right after a mistake, or you tilt and the next move craters too. If it cliffs, that becomes a coaching cue, not a mystery.
Honest proof it’s working
For each pattern you train, we track its mistake rate in your real games over time — with your untrained patterns as a within-you control. If your fork mistakes drop while the rest stay flat, that’s a real signal. If it’s noise, we say “no clear change yet.”
Where the coach fits
The coach is the last step of a loop: you play a real game, review it to find what went wrong, see how you rank vs your level in your Skill Profile, and then the coach drills the weakness that’s costing you most. Play again, and the transfer measurement tells you — honestly — whether the needle is moving.
