GreenGlasses

Point your phone at a grocery shelf; it tells you which products are vegan.

Stack: SwiftUI, AVFoundation, Anthropic vision API

What It Does

Take a picture of a shelf at a grocery store and it figures out what's vegan and what's not just from the picture!

How it works

I wanted this one for a long time. A raw AI call was way too slow so I've broken that up into pieces, streamed the output, done lookups in the background and got it working pretty smoothly and usefully. There's probably room to make this faster over time but for now, pretty darned time-saving!

Built with

iOS: SwiftUI + AVFoundation for the camera pipeline.
Vision: Anthropic's vision API. One call per capture, returns structured verdicts per product.
State: None persisted. Every session starts fresh.
