Short answer

Can my AI check food ingredients for allergens?

Yes. Your AI uses Open Food Facts to pull ingredient lists from barcodes or product names and compares them against your specific allergy list. You'll get a clear breakdown of matching ingredients and potential risks.

The results of your scan

What you get from the analysis

The AI processes the raw product data into actionable safety checks.

MATCHES

Identified allergens

The AI flags specific ingredients that match your dietary restrictions. It pulls these directly from the product's nutritional profile.

RISKS

Hidden ingredient warnings

Your agent identifies ingredients that might contain allergens, such as derivatives or additives. This helps you spot risks that aren't obvious at first glance.

DATA

Full ingredient lists

The AI retrieves the complete list of ingredients and nutritional facts. You get the raw data needed to make an informed decision.

HUMAN

Final safety decision

The AI provides the analysis, but you must make the final call on whether a product is safe to consume. It acts as a second set of eyes, not a medical professional.

The workflow

What your AI does when you scan a product.

The AI bridges the gap between a physical product and your dietary requirements.

  1. Identify the product

    Your AI identifies the specific food item by reading the barcode or searching for the product name.
