Read your own games.

A private review of your completed Chess.com games. It runs a real engine over the moves you actually played, separates how you behave in bullet, blitz and rapid, and shows you the exact moments you give points away.

Reads completed games only. No login, no engine during live play, nothing leaves your browser except the public username lookup.

What it actually does

Not "develop your pieces and castle." It looks at the games you played and answers specific questions.

1
Real engine on your moves. Pick any game and it evaluates every position, grades each move, and shows the move you should have played and why.
2
Bullet, blitz and rapid are different people. Each time control gets its own scorecard and its own advice, because your habits change with the clock.
3
Where the game breaks. It isolates the phase and the move range where you lose points, and reads your clock to find time-trouble patterns.
4
Your style, then concrete openings. It reads how you play and recommends specific openings that fit, plus a grandmaster whose approach matches yours.
5
What you already do well. Strengths to protect, not just leaks to fix.

The same board you read after every game — now with the engine's verdict attached.
