Show HN: I built an AI Chess Coach w/o4-mini and Stockfish (chesscoachgpt.com)

I built a simple chess bot that pairs o4-mini w/reasoning grounded in Stockfish’s engine analysis. It explains moves clearly, suggests tactics, and helps you understand why moves are good (or bad).

Try it out here: https://www.chesscoachgpt.com/

Would love feedback.
