An AI chess coach that explains every move
Coach Moji is no longer just a friendly face — it has grown into a genuine AI chess coach that sits beside you through every game review. Move by move, it explains what actually happened: why a quiet move was so strong, exactly where the position turned, and what the winning idea was that slipped past you. Instead of a wall of numbers, you get a clear, human explanation of your own chess game.
Explains every move
In your game review, Coach Moji puts each key moment into plain words — the plan behind the best move, the threat you overlooked, the reason the evaluation swung — so you understand your chess, not just your score.
Never wait on a chess engine again
Your analysis runs a powerful chess engine right on your own device, and on an older phone that can take a few seconds. When it does, Coach Moji keeps you company — reassuring you, offering a tip, and letting you know everything is on track — so a slower moment never feels like something has broken.
Stays with you while it thinks
If the engine needs a moment to finish analyzing, Coach Moji steps in so you are never left wondering — turning dead waiting time into a friendly, guided pause.
Learn chess as you play
This is the part we are proudest of. Over in Play Bots, if you genuinely do not know what to do, your AI chess coach will guide you — pointing you toward the right idea and helping you find a strong move on your own. For a beginner that is nothing short of a revolution: instead of losing and never knowing why, you are taught, in the moment, how to actually play chess. It is like having a personal chess coach sitting right next to you for every single game.
Teaches you how to play
Not sure of your move against a bot? Coach Moji shows you the way — so every game leaves you a stronger player, not just tired.
