Questions about Solpento
Is Solpento a replacement for a human chess coach?
No. A good human coach can understand your broader goals, follow your progress, and adapt training over time. Solpento is designed to complement that work—or help when regular coaching isn't available—by turning one important mistake from your game into a focused guided review.
Is Solpento just an LLM? Can it really understand chess?
Solpento uses an LLM to guide the conversation, but it does not rely on the model alone for chess facts. Positions and moves are grounded in Stockfish and structured chess analysis, while the conversation is carefully guided around the lesson. Mistakes can still happen, especially during beta, and we're continuously improving the safeguards and review quality.
Is this another tactics trainer?
No. Solpento starts with a mistake from your own game—not a position chosen because it contains a puzzle. You begin by explaining your idea before receiving progressive guidance.
