Discover the patterns behind your chess games
ChessPivot analyzes every game individually, then connects the dots to reveal your recurring strengths, weaknesses, and the decisions that shape your results.
Missed fork — a knight won two pieces at once.
See ChessPivot in action
It all starts with your games.
One game tells you what went wrong. Hundreds of games tell you why you keep losing.
From diagnosis to training, every step is built on your real games.

Import your games
Connect Chess.com or Lichess — or import your over-the-board games from a PGN or Lichess study.

We identify recurring mistakes
Every mistake is caught move by move, then cross-referenced across all your games. Not a vague score: the exact situation — missed fork, hung piece, defender left in place — with its frequency and trend.

We rank what costs you the most
Your weaknesses appear ordered by what they truly cost you. You see at a glance where to start.

Train on YOUR positions
Drills built from your real mistakes, never generic puzzles — calibrated to your level.

A single 0–100 score for how clean your play is, climbing as your weaknesses fade.

Understand a player, not just their games.
Understanding your games isn’t enough: ChessPivot models how you play. It builds a faithful portrait of a player — their error patterns, their hierarchy, their tendencies. For you, it’s the exact diagnosis of what makes you lose, and the raw material of your training; for an opponent, it’s precise enough to replay their style on the board. Powered by Mimesis™.
Built on the latest Stockfish engine and modern AI models.

The Solidity Index
Ratings tell you who you beat. Solidity tells you how clean you actually played. 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.
How we calculate itWhy ChessPivot
Engine-verified coaching

We replay your real mistakes — the missed forks, hung pieces and overlooked pins — and drill them until they’re gone.
