The RETSUM Engine is the adaptive intelligence at the core of MindBoard—designed to transform chess from a game into a powerful tool for human thinking. More than a traditional engine, RETSUM combines elite-level chess analysis with conversational intelligence, allowing it to understand not just what move you make, but why you make it.

What sets RETSUM apart is that it acts as a personal chess coach—one that teaches you as it learns you. It studies your patterns, recognizes your strengths and blind spots, and delivers real-time guidance tailored specifically to your thinking style. Every move becomes a lesson, every game becomes a training session, and every interaction sharpens your decision-making.
