Hi PH! I built KnowPitch (球知) - it turns any knowledge domain into a football formation. Give it a topic (e.g. "machine learning", "inflation", "React hooks") and it maps concepts onto a real pitch: - Goalkeeper = the foundational principle you can't compromise - Defenders = core concepts - Midfielders = mechanisms and methods - Forwards = applications and conclusions - Head coach = the one-sentence core idea It renders an SVG formation diagram + ELI5-style player cards (explained like you're 5, not like you're stupid) + a tactics board showing your learning path. Built because I kept forgetting what I learned. Visualizing knowledge as a team made it stick. It's open source (MIT), local-first, runs entirely on your machine - no API keys, no data leaves your device. Try the live demo, then star the repo. Curious which topics you'd want mapped next!
