Question 1

What is an AI chess coach?

Accepted Answer

An AI chess coach is a software that analyses your chess games automatically, identifies your recurring mistakes and weaknesses, and gives you personalised advice to improve — without needing a human coach. ChessMentor AI uses Stockfish 17.1 (the world's strongest engine) combined with an AI to explain why you blunder and what to work on.

Question 2

How does ChessMentor AI help me improve at chess?

Accepted Answer

ChessMentor AI imports your games from Chess.com or Lichess, analyses every move with Stockfish 17.1, detects patterns in your mistakes (missed tactics, weak openings, endgame errors), and generates a personalised coaching report. You can then chat with the AI coach to ask questions about your games and get a study plan.

Question 3

Is ChessMentor AI free?

Accepted Answer

Yes. Game import and Stockfish analysis are completely free. Pro features (AI coaching report, chat with AI coach, progress tracking) are available with a subscription.

Question 4

How is ChessMentor AI different from AimChess or DecodeChess?

Accepted Answer

Unlike AimChess (which gives data but no explanations) and DecodeChess (which explains moves but suffers from technical issues), ChessMentor AI combines deep Stockfish analysis with plain-language coaching narratives and tracks your progress over time. It works with both Chess.com and Lichess.

Question 5

Can I use ChessMentor AI with Chess.com or Lichess?

Accepted Answer

Yes. ChessMentor AI connects directly to both Chess.com and Lichess. It automatically imports your recent games, analyses them with Stockfish 17.1, and builds your coaching profile.

Question 6

How accurate is the Stockfish analysis?

Accepted Answer

ChessMentor AI uses Stockfish 17.1 lite, running directly in your browser via WebAssembly. It analyses each position at depth 22, giving centipawn accuracy comparable to what Chess.com and Lichess use for their own analysis tools.
