Game review
Every move checked. Every mistake explained.
Stockfish measures what each mistake cost. The moments that decided the game are explained in plain words: what went wrong, what was better, and the idea behind it.
Every move an explanation names is checked against the engine, so it never recommends a move Stockfish didn't find.

AI Coach
The mistakes you keep making, found for you.
Across your games, the AI Coach finds what keeps costing you points: the phase where your accuracy drops, the tactics you miss, and where the clock starts to hurt.
Then it turns them into training: a puzzle pack weighted by those themes, a study plan, and your own mistakes to play again.

My Second
Know your next opponent before you sit down.
Give it a name from Lichess, Chess.com or FIDE. It studies their games the way a professional second would: what they play, how they answer your repertoire, and the line they handle worst.
Then rehearse: play a whole game against a simulation of them, built from their own games.
