GreenLens wins Build North with plant doctor

GreenLens is less a breakthrough in plant diagnosis than a compelling demo of the modern agent-app stack: multimodal input, device sensors, authentication, and persistent context in one mobile workflow.

• –Expo’s LiDAR and RealityKit modules push React Native beyond standard CRUD apps.
• –The agentic approach promises ongoing plant context instead of one-off image classification.
• –Clerk and SurrealDB let a small team focus on product behavior rather than infrastructure.
• –Diagnostic reliability and transparent uncertainty will determine whether this grows beyond a strong hackathon demo.
