Slim AI is an AI calorie tracker that counts calories and macros from one photo of your meal. Every meal also gets a Health Score from 0 to 100, so you see how much you eat and what that food does for your body. You don't have to type anything or dig through a food database. Point the camera at your plate, check the numbers and fix anything that looks off with one tap. HOW SLIM AI WORKS 1. Answer a short questionnaire about your body, your goal and your lifestyle. 2. Get daily calorie and macro targets calculated for you, not for an average person. 3. Log meals with a photo, a barcode, a food label or your voice. 4. Follow your calories, protein, carbs, fat and Health Score in one place. LOG FOOD IN SECONDS • Meal photo: AI recognizes the food on your plate and estimates calories and macros • Barcode scanner for packaged food • Food label scanner that reads the nutrition table for you • Voice logging: say what you ate and Slim AI adds it to your food diary • One-tap fix for any value, so you always have the final say HEALTH SCORE: MORE THAN CALORIES Two meals with the same calories can do very different things to your body. Slim AI scores every meal by looking at its ingredients, how processed it is and how much sugar, fat and fiber it has. Four risk scores show how a meal may affect acne, bloating, brain fog and aging. You also see the vitamins (D, C, B12, folate, A), minerals (magnesium, iron, potassium, calcium, zinc) and other nutrients (fiber, omega-3, sodium, cholesterol, antioxidants) in each meal. BODY ANALYSIS Take a photo of your body and Slim AI estimates your body fat percentage as a range within seconds. Then generate an AI visualization of the shape you could reach and see it side by side with how you look today. Save it or share it with friends.
