ChessInt — Chess Intelligence
ChessInt (short for Chess Intelligence) turns your real games into a clear plan for improvement. Connect your Lichess or Chess.com account and ChessInt runs full engine analysis on every game, then surfaces the patterns that actually cost you rating — the openings you drift in, the tactics you miss, the endgames you let slip, and how you play under time pressure.
What ChessInt does
- Game analysis — Stockfish runs locally in your browser, so your whole history gets evaluated without waiting on a server queue.
- Recurring weaknesses — instead of one-off blunders, ChessInt finds the mistakes you make again and again, by phase, motif, and opening.
- Opening intelligence — see which lines win for you and which quietly lose, with real win-rates from your own games.
- A personal AI coach — a written report that reads like a coach who has studied hundreds of your games, with concrete drills to fix each weakness.
- Tactics from your mistakes — puzzles generated from positions you actually got wrong.
Who built it
ChessInt is designed and built by Udit Raj, an independent engineer and product builder. You can see more of his work — including Evil Eye — over at uditraj.site.
