In 10 seconds: your style, your leaks, the openings that suit you, what pressure does to you. Then it coaches.

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.
Love how it pulls straight from your username, no friction at all. One thing that would make this even better: a "compare to last month" view so you can see whether the leaks are actually shrinking over time, not just a static snapshot of where you stand right now.
Pulled up my Lichess username and it actually nailed the openings I overthink. The puzzles based on my own blunders hit different than the usual spaced repetition stuff.
Pulled up my lichess username and it nailed a weakness i've been stuck on for months, and tapping through to the exact turning point move made it click instantly.
honestly the "no signup, just username" thing is kind of amazing, pulled up my lichess and within seconds it actually flagged a tactic pattern i keep falling for in the sicilian. that hit different than the usual generic review.
