Hello HN, longtime lurker, finally I have something to show :)

IngrediCheck is a Food Scanning App. It is meant to help with Grocery Shopping, for people who have unique dietary restrictions or preferences. I made it because we were reading too many food labels when Grocery Shopping. If you are shopping for a family, the list of dietary restrictions can get long.

The way it works is

1. You enter your dietary restrictions or preferences in natural language. This can be quite flexible. Examples:

    - I am allergic to oats and peanuts.
    - I want to avoid seed oils.
    - Dr Berg on YouTube said avoid Maltodextrin.

2. When Grocery Shopping, scan the Barcode of a packaged food item to get an instant analysis whether it meets your dietary preferences.

Hope someone finds it useful!

I had fun using LLMs for:

    1. Validating dietary preference entered in natural language.
    2. Matching natural language dietary preferences to an ingredients list.
    3. Extracting structured ingredients list from OCR of package product images.
    4. And now I plan to use Agents to scour the web for Packaged Food Item details.

PS:

    - only works for Ingredients right now, not Nutrition label.
    - only on iPhone right now.
    - only in US, Canada, UK, India right now.
