Question 1

What is CaissaLM?

Accepted Answer

CaissaLM is a chess AI trainer that pairs an adaptive Stockfish 16 opponent with real-time AI coaching. Every move you play is analyzed and explained, helping you improve faster than playing against a silent engine.

Question 2

How is CaissaLM different from chess.com or Lichess?

Accepted Answer

Chess.com and Lichess focus on matchmaking and post-game review. CaissaLM focuses on coaching: every game is a lesson with live commentary, and the AI explains why a move was good or bad in plain English.

What ELO range does the AI cover?

Accepted Answer

CaissaLM's AI scales from 400 ELO (true beginner) to 2800 ELO (super-grandmaster) so it can challenge players at any level.

Question 4

Is there a free trial?

Accepted Answer

Yes — every new account gets one free game with full AI coaching, and a 7-day free trial of the full subscription with no charge until the trial ends.
