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 18 (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 18, shows your style radar, builds puzzles from your own mistakes, and comments 1 game in plain words for free. Pro unlocks the AI coach on every game.

Question 3

Is ChessMentor AI free?

Accepted Answer

Yes. Game import, Stockfish analysis, style radar, puzzles from your mistakes, and 1 AI-coached game are free. Pro ($14.99/mo, 15-day trial) unlocks the coach on every game plus on-demand move explanations.

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 18, and builds your coaching profile.

Question 6

How accurate is the Stockfish analysis?

Accepted Answer

ChessMentor AI uses Stockfish 18 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.
