What Cal AI Does
Cal AI is an AI-powered mobile app that instantly tracks calories and macronutrients by analyzing photos of food. Users take a photo of their meal, and Cal AI's multimodal AI model — trained on thousands of food images — identifies ingredients, estimates portion sizes using the phone's depth sensor for volume calculation, and provides a complete nutritional breakdown. The app eliminates the tedious manual input required by traditional calorie trackers like MyFitnessPal. Features include barcode scanning, Food Memory for frequently eaten meals, Groups for logging meals with friends, and Progress Photos.
