Inside a review

What you get with every game

Ask, argue, test your own idea

The coach sits beside the board. Ask why a move lost, or suggest what you would have played instead: your idea gets measured against the engine and answered straight, and every line it mentions is one tap from playing out on the board.

See the whole game in one card

Accuracy for both sides, every move graded, and the exact moment the game turned. The overview points you at the two or three moments actually worth understanding, so a review takes minutes, not an evening.

A lesson that asks first

The walkthrough takes you to each turning point and asks what you were thinking before it tells you anything. One question at a time, answered on the board, the same on your phone as at your desk.

How it works

  1. Bring a game

    Enter your chess.com username and pick from your last 50 games, or open a famous classic instead.

  2. The engine reads it

    Stockfish annotates every move and finds the turning points that decided the game.

  3. The coach asks

    It takes you to each turning point and asks what you were thinking. You answer on the board, and it grades the move you meant.

The engine has the answer. The coach gives you the lesson.

The engine can tell you the best move was Nf3. It won't tell you why yours was tempting, which moment out of forty decided the game, or what to look for next time. A language model guessing on its own is just confidence without proof. This coach does the teaching, and every word of it comes from the engine's read of the exact position in front of you.

Grounded
Every eval and every line comes from the engine's analysis of the position on the board, never from a model's confident guess.
Shows its work
When the coach says a move loses a piece, the line that loses the piece is on the board, ready to play through.
Argue back
Think you had something better? Suggest it. Your move gets measured and answered, not politely deflected.

Your move.

Bring a game you actually played, or start with a classic. Either way, the first question arrives in about twenty seconds.
