Step 4

See it click

Insights track your improvement across your games, so you can watch your progress add up.

Train with your AI Coach

Reviewing is half the work. The other half is playing and practicing, with the same AI Coach on the other side of the board.

A live sparring game against the ChessCoda Coach — Play your AI Coach
Spar at your own level, any time. It plays the moves a human would play, not perfect engine chess. Finished games land in your library and get their own review, like any other game.

The practice solver with theme chips and a puzzle from the player's own game — Drills from your own games
An endless stream of puzzles built from the mistakes you actually make, themed around what your AI Coach wants you to sharpen next. The position you slipped in comes back until the pattern sticks.

See what's holding you back

One game teaches a lesson. A hundred games tell the truth. Insights connects your whole library: your most frequent mistakes, your opening repertoire and where you usually leave theory, accuracy trends, phase strength, and how you handle the clock.

Slice all of it by format, color, and opponent strength. A blitz habit and a classical habit are different problems, and your AI Coach treats them that way.

The opening repertoire insight: most played lines, scores, and where theory ends — A real repertoire: lines, scores, and the move where theory usually ends.

Meet your AI Coach

Not a score. Not a centipawn. A clear explanation of what happened in your game, and what to do about it.

CoachMove 18, middlegame

Your knight on d5 was doing two jobs: blocking the e-file and covering c7. Trading it with 18.Nxe7 gave both up at once, and the rook invaded two moves later. When one piece holds your position together, think twice before trading it.

CoachMove 31, rook endgame

Down a pawn here, the real mistake was trading rooks. The pawn endgame is lost, but with rooks on the board your active king gives real drawing chances. Keep the pieces that keep you in the game.

CoachGame summary

You came out of the opening better in all three games this week, then drifted around move 20 when there was no obvious plan. Next time, pick a target before you push pawns. That's what we'll work on.
