Review your chess games — free
The game you just lost has every answer you need in it. We run a full engine review of it — move-quality labels, an evaluation bar, and the move you missed at each turning point — so you stop closing the loss and start learning from it.
Free accounts review a few games every week. Standard and Premium add unlimited reviews.
Move-quality labels you already know
Every move is graded — best, good, inaccuracy, mistake, blunder — so you can scan a whole game and spot the moments that actually changed the result.
An evaluation bar for the whole game
Stockfish runs on every position. The eval bar shows who was winning and by how much, in win-percentage terms — so a slip while you’re crushing is judged more gently than the same slip at equality.
The move you should have played
The engine’s preferred move is drawn right on the board next to what you played. The gap between the two is the lesson — and it’s sitting in every game you’ve ever lost.
Review & Improve: find it yourself
The highest-value habit in chess, built in. We replay the turning points of your game and ask you to find the move the engine preferred — active recall on your own mistakes, not just being shown the answer.
An honest per-game rating estimate
Each reviewed game gets an estimated strength based on how closely your moves matched the engine in win-percentage terms. One game is approximate; the trend across many is the real signal.
It feeds your coach
Reviews aren’t a dead end. The recurring mistakes they surface become the training plan your built-in coach drills — the loop that actually moves your rating.
How a review fits the loop
Reviewing one game tells you what went wrong in that game. Reviewing ten reveals the pattern — the blunder that always shows up between moves 20 and 30, the endgame you can’t convert, the position type that makes you fall apart. That pattern is the thing worth training, and it only appears once you actually look.
From there, your Skill Profile ranks each part of your game against players at your level, and the built-in coach turns your recurring mistakes into a spaced-repetition training plan. Want the whole picture? Read the improvement-loop guide.
Play a game, then review it instead of queueing the next one. That one change is the difference between a plateau and getting better.
