SideLine

Download a coach. Deploy a ref. Upgrade the game. SideLine is a modular AI sports robot designed to solve the growing shortage of coaches and referees in youth sports, a $40B industry growing ~10% annually as NIL money and private equity raise competition levels. Powered by a Qwen vision-language model, SideLine watches gameplay in real time, delivers technical coaching feedback, and can switch into referee mode to make unbiased calls. Users can download sport-specific modules like Tennis Coach Pro to get drill feedback, movement corrections, and automated officiating. https://sideline-beige.vercel.app/
