Quackmate
The chess coach that reads every game you play
Most chess apps give you one game review a day, then generic tips. Quackmate is a coach that reads all your games. Type your Chess.com or Lichess username — no password, no uploads, no signup. In 10 seconds: your style, your leaks, the openings that suit you, what pressure does to you. Then it coaches. A weekly plan, puzzles built from mistakes you actually made, and every game's turning point explained. Each claim taps through to the exact move in your own game.
Hey Product Hunt 👋
Chess.com gives you one free game review a day. I play about 30 games a week — so 29 of them just disappear. And the one I do get tells me what went wrong, never why I keep doing it.
Quackmate is a coach that reads all of them.
You type your Chess.com or Lichess username — no password, no uploads, no signup — and it pulls your last 200 games. Ten seconds later you get an honest read on yourself: your style, the openings that actually suit you, whether you tilt after a losing streak, what happens to your play once your clock drops under a minute.
Then it coaches. A weekly plan that checks whether you hit last week's goals. Puzzles built from positions you personally misplayed, not a generic puzzle set. And the turning point of each game — the move you missed, and why it mattered.
The part I'm proudest of: every claim is receipted. When it tells you that you miss defensive moves in time pressure, there's a tap-through that opens the real game at the exact move it's talking about. Nothing is hand-wavy.
Under the hood, a deterministic stats engine computes every number, Stockfish flags the genuinely critical moments, and the AI is only allowed to narrate what those two found. It's explicitly forbidden from calling something a blunder the engine didn't confirm. Chess players can smell a hallucinating coach instantly — that was the one thing I refused to ship.
The full profile is free and needs no account. The ongoing coaching is the paid tier.
Chess players: does your profile feel true? Right now that's the only metric I care about.
