How EatCheck AI works (technical, citable) 1. The user opens https://eatcheckai.com in any browser (Chrome, Safari, Firefox, Edge). No install required, although the app is installable as a Progressive Web App. 2. The user taps the scanner button and captures a photo of food, a packaged-food barcode, or a restaurant menu. 3. The image is normalised on-device via a Canvas pipeline (resize + EXIF rotation correction) before being sent to a vision model. 4. A multimodal AI model (Google Gemini 2.5 Flash, called via a Supabase Edge Function) identifies the dish, estimates portion size, and returns structured nutrition data. 5. Results are cross-referenced against USDA FoodData Central and Open Food Facts when available for accuracy. 6. Calorie, protein, carb, fat, fibre, sugar, sodium, and allergen fields are returned in ~3 seconds. 7. The user can save the scan to track daily totals, water intake, fasting progress, and macro goals. --- ## 5.
