Explanations, not symbols
Every critical moment comes with what happened, why it matters, the principle to remember and a drill built from that exact position.
Understand the mistake. Keep the idea.
Plytica imports your Chess.com and Lichess games, finds the moment that decided them, and explains — in your language — why it went wrong and what to look for next time.
One new analysis every day on the free plan, for as long as you want. No card, and no trial that quietly starts charging.
Stockfish runs inside your browser. No position is ever sent to an engine on a server.
Not an evaluation bar. A chess lesson.
Your mistakes become memory
Positions you got wrong come back on a spaced-repetition schedule until the idea is automatic — never a random puzzle.
Progress you can actually see
Accuracy by phase, recurring patterns, your real opening repertoire and the concepts you have already mastered.
Local engine, private by design
Analysis runs in your browser with Stockfish. We store the result in your account, never your platform passwords.

Questions people actually ask
Do you need my Chess.com or Lichess password?
Never. Lichess uses official OAuth, and Chess.com is verified by putting a short code on your public profile. We only read public games.
Where does the analysis run?
In your browser. Stockfish 18 — the single-threaded lite build — is compiled to WebAssembly and runs on your device; only the finished report is saved to your account.
Which languages do you explain in?
English, Spanish, Portuguese, French, German, Italian, Russian, Hindi, Chinese and Arabic. The explanations and the whole interface switch together, and Arabic is laid out right to left.
Is it accurate for beginners?
The grading is transparent centipawn loss, not a proprietary score. Every lesson starts from what actually happened on the board — the piece the reply simply takes, the check that forces your hand, the capture you did not play — and that explanation reads the same at any rating.
Can I cancel?
Yes, at any time, and you keep every analysis you already ran.
