AI-Powered Chess Companion
Play Chess with a
Witty AI Buddy
Chester watches your games, drops sarcastic commentary, and quietly makes you a better player. No lectures. No boring tutorials. Just chess with personality.
How It Works
Three steps. Zero setup. Just you, a chessboard, and an AI with opinions.
Make Your Move
Play white against an adaptive AI engine. It matches your skill level — the better you get, the harder it plays.
Chester Reacts
Your AI buddy watches every move and drops real-time commentary. Sometimes helpful, sometimes sarcastic — always honest.
Get Better
Your Elo rating tracks your progress. Chester remembers your play style and adapts his coaching as you improve.
Meet Chester
He's not a coach. He's the friend watching your game who can't help but comment.
You blunder your queen
That's... a choice.
You play a brilliant fork
Saw that. Nice.
You castle early
Smart. Safety first.
You move your king to the center
Bold. Very bold.
Not Your Average Chess App
Built for players who want more than a silent opponent.
AI That Adapts to You
Elo-rated difficulty that scales automatically. Below 1000? Easy mode. Climbing past 1400? Chester brings the heat.
Real Personality
Chester isn't a generic chatbot. He's dry, witty, and occasionally roasts your blunders. "That's... a choice."
Live Move Analysis
Every move gets evaluated in real time. Chester explains what happened, what you missed, and what to watch for.
8 Board Themes
From classic wood grain to volcanic Obsidian. Your choice syncs across all your devices.
