April 5, 2026 · From the archive, written in the Professor's voice before our October 2026 redesign from greenside.ai

What happened

Greenside AI uses the iPhone's GPUs and Neural Engine to perform real-time biomechanical analysis of your golf swing, even offline. Their system applies predictive modeling to dissect swing mechanics and offer precise coaching feedback anywhere globally. This leverages on-device machine learning to bypass the need for cloud connectivity while maintaining high accuracy.

Why it matters

This demonstrates the power of edge AI—running complex models locally on smartphones to enable fast, accessible, and privacy-preserving analysis. It challenges the assumption that AI coaching requires constant internet or expensive hardware, making elite-level feedback portable and democratized.

Who's doing it

Greenside AI is actively deploying this technology, enabling golfers worldwide to improve swings with AI insights directly on their iPhones, reportedly increasing swing accuracy and consistency through personalized recommendations.
