Zenaiya is a conversational AI chess coach and tutor powered by Grok. Traditional chess engines output cold scores like +1.4 without explaining why a move failed. Zenaiya reviews your matches in plain language, explaining tactical blunders, missed opportunities, and opening principles like a private instructor. Features real-time interactive chat to ask questions about any position and an Adaptive Response Timing engine for realistic human-like practice. Available free on iOS & Android.
