Crop Check
Built at Meta Global AI Developer Hackathon · Oct 26, 2026 · Remote

Smallholder farmers lose crops to leaf diseases they can't identify in time, and expert help is far away. Crop Check is a mobile-first web app where a farmer photographs a sick crop leaf and gets a diagnosis and a practical treatment plan in seconds. Each scan also feeds a live outbreak map, so nearby farmers are warned before a disease spreads. It runs in a phone browser with no download, uses a light design for slow networks, and has a WhatsApp help button. Built solo.
