You repeat the same mistakes. We model them — and build the tailored training that fixes them.
ChessPivot names the exact situations that keep recurring in your play, shows you which one costs you most, and turns them into tailored drills — from your own games.
We built Mimesis™, a technology that models a player down to the exact error pattern: yours, to target your progress; your opponents', to prepare you to face them. It’s built on the latest generation of Stockfish and the best AI available.
Missed fork — a knight won two pieces at once.
It all starts with your games.

Technology that models players.
From hundreds of games, Mimesis™ builds a faithful portrait of a player: their error patterns, their hierarchy, their tendencies. That portrait is precise enough to replay an opponent’s style on the board. For you, it becomes the exact diagnosis of what makes you lose — and the raw material of your training.
Built on the latest Stockfish engine and the best AI available.
The Solidity Index
A single number, 0 to 100, that captures how clean your play really is. The fewer exploitable mistakes you leave on the board, the higher it climbs — so you watch real improvement, game after game, instead of guessing from a rating that bounces around.
