chess.rodeo - Free Chess Analysis

See how the game went the moment it ends — accuracy, blunders and mistakes — on the chess.com and Lichess game-over screen.

chess.rodeo provides deep analysis of your Chess.com and Lichess games using Stockfish engine. Features: • The verdict right on the game-over screen — accuracy, blunders and mistakes, before you click anything • One-click import from Chess.com and Lichess • Deep Stockfish analysis (depth 15+) • Move-by-move classification (best, excellent, mistake, blunder) • Accuracy scores using Lichess formula • Opening detection with ECO codes • Game phase analysis (opening, middlegame, endgame) • Batch analysis across multiple games • Identify patterns and weaknesses How to use: 1. Play a game on Chess.com or Lichess 2. When it ends, the button already tells you how it went: "87% accurate · 1 blunder, 1 mistake" 3. Click "Analyze on chess.rodeo" for the full move-by-move analysis 4. Get personalized improvement recommendations The verdict on the button is free and needs no account: chess.rodeo keeps a large store of positions that have already been analysed, and most games walk through many of them. While it covers only part of your game it says so — "87% accurate · 16 of 32 moves" — because a number without its coverage reads as final when it is not. A chess.rodeo Pro subscription has the engine fill in the rest, so the verdict covers the whole game. Privacy: The extension reads the finished game's moves from Chess.com or Lichess — public game data — and sends them to chess.rodeo to get the verdict back. That is the whole request: no account name, no analytics of its own, no tracking, nothing stored on your device. If you are signed in to chess.rodeo, your session token is sent with it so the server knows your subscription; it goes to chess.rodeo and nowhere else. Full policy: https://chess.rodeo/privacy
