Chess coaching from your own games.
ChessCoda reviews the games you actually play and explains what to fix. Then it drills those weaknesses with puzzles from a curated database. Clear coaching for every level, from beginner to strong club player.
How it works
Bring your games
Connect Lichess or Chess.com, or paste a PGN. Your games land in one place.
Your coach reviews every move
Powered by a real engine, your coach grades each move and finds the moments that decided the game.
Understand it, then fix it
Plain-language explanations of your key moments, the better plan, and what it means for your next game. Tuned to your level, not a grandmaster's.
Meet your coach
Not a score. Not a centipawn. A clear explanation of what happened in your game, and what to do about it.
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.
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.
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.
Not just numbers. Lessons.
Engines tell you what was wrong. Your coach tells you why, and what to do about it.
Every move graded
From brilliant to blunder, every move gets a grade and the better move when you slip.
Find the turning points
The win-probability graph takes you straight to the moments that decided the game.
Tuned to your level
A 1200 and a 1900 don't need the same lesson. What counts as a mistake, and how it's explained, adapts to you.
