How does the personalized scoring work?
When you create a profile, you describe your dietary needs in plain English (e.g., "I'm diabetic and trying to lose weight"). Our AI understands your requirements and creates a scoring algorithm specifically for you. Every product is then evaluated against YOUR needs, not generic standards.
Can I use it for my whole family?
Absolutely! You can create separate profiles for each family member with their specific dietary needs. The free version supports up to 3 profiles, while FoodGrader+ allows unlimited profiles. Switch between profiles instantly while shopping.
What if a product isn't in the database?
If we can't find a product by barcode, you can use our AI Vision feature to take a photo of the nutrition label. Our AI will extract all the information and provide a personalized score. Free users get 30 Vision scans, while FoodGrader+ users get unlimited.
