Questions & answers

Phiamos is your personal chess coach. Connect your Lichess and/or Chess.com account and we pull your games, run every move through Stockfish, and build a personal dashboard that shows why you lose — your blunders, recurring patterns, and exactly what to work on next.

The Free plan is free forever — your dashboard, full Stockfish analysis, and puzzles from your own games. Pro is $6.99/month (with a 7-day free trial) and adds the Coach, opponent scouting, deeper engine analysis, and unlimited game history. See pricing.

Lichess, Chess.com, or both. Connect either or both and we combine your games into one dashboard. We only ever read your public games — we never post or play on your behalf.

Every game runs through the Stockfish engine. We surface your accuracy, count your blunders, mistakes, and inaccuracies, and pull out the critical moments where the game turned — with the engine’s best line and the evaluation swing, plus an interactive board and eval graph.

On Free, we import and analyze your most recent 100 standard games per connected platform. Pro unlocks unlimited game history and a priority analysis queue.

As little as possible. Your identity (Google sign-in) is handled by Firebase — we don’t store your email or name in our own database. We keep your account ID, your connected Lichess username, and your chess data (games and analysis). That’s it.

The Coach (ask anything about your play and get answers grounded in your own games), opponent scouting before a match, deeper engine analysis, unlimited history, and priority in the analysis queue.

Anytime — open Accountfrom the menu and manage your billing through the secure Stripe portal. If you cancel during the 7-day trial, you’re never charged.

From your own games. Phiamos turns the positions where you went wrong into tactics puzzles, so you practice exactly the patterns you keep missing.

Yes! Connect your Lichess account, your Chess.com account, or both — your games from each are pulled in and combined into one dashboard.
