Your coach's read

Stop guessing why you lost.

Phiamos pinpoints the exact moments a game turned — the blunder, the missed win, the move that should’ve been — and shows you what to play instead. A world-class engine does the heavy lifting; you just get the verdict.

Critical moments

Blunder ??· move 18+1.2 → −2.1

You played Qf3 — it hung a knight. Best was Qe2.

Mistake ?· move 24−0.3 → −1.6

Rfd1 gave up the open file. Best was Re1.

Inaccuracy ?!· move 31−1.6 → −2.0

h6 loosened the king. Best was Kg7.

Studies the player, not the game

Your patterns, not just one game.

One blunder is noise. Fifty games is a signal. Phiamos learns where you consistently fall apart — the middlegame, time pressure, a specific opening — so you fix the cause, not the symptom. That’s the difference between an engine and a coach.

A plan, not a wall of lines

Know exactly what to work on.

Your coach turns your weaknesses into a focused plan — the tactics to drill, the endgames to practice, the openings to shore up — so every session targets what’s actually holding you back.

Recommended focus

Practice tactics — forks, pins, skewers, and discovered attacks.

The story

Built by a chess obsessive, for chess obsessives

I’m Eddy— an engineer and lifelong chess player. After years of clicking “analyze” and getting a wall of engine lines that told me what went wrong but never why I keep doing it, I got fed up.

I didn’t need another engine. I needed a coach who’d watched all my games and could say, “You keep collapsing in the middlegame under time pressure — fix that.” So I built Phiamos to do exactly that: analyze the player, not just the game.
