How it works

Three ways to scan

📦

Barcode scan

Point at any barcode. Libby pulls the product, scores every ingredient, and shows what's driving the number — under a second.

📸

Photo scan

No barcode? Snap the ingredient label. On-device AI reads the text and sends it for analysis. Works on any product anywhere.

🛒

Grocery Haul

Pro only. One photo of your entire cart. Every product detected and scored simultaneously, ranked worst to best.

The science

Built on real research

Every ingredient has a truth score from 0–100, calculated from published studies in PubMed, Semantic Scholar, and OpenAlex. Not opinions, not brand partnerships. The more evidence of harm, the lower the score.
