Diet AI is a simple, chat-based calorie and diet tracking app. Just tell the AI what you ate - it does the math for you. Diet AI is a fully chat-based calorie counter that removes tedious forms and setup. Type "I had grilled chicken, rice and a salad" or just send a photo of your meal, and your log is done. Your personal AI coach calculates the calories and macronutrient balance, tells you how many calories you have left today, and even suggests what to eat next - all in a natural conversation. If food-logging apps never stuck for you, this one is different. No complicated menus, no endless daily data entry, no guilt. Overate today? Diet AI won't scold you - it gently helps you balance things out tomorrow. WHO IT'S FOR - Beginners who want to lose weight but don't know where to start - Anyone who found calorie counting or food logging too tedious to keep up - People burned out by traditional tracking apps - Those who care about post-pregnancy changes, bloating or plateaus - Anyone who wants a healthy, sustainable approach instead of extreme restriction - People who want an effortless view of their macros and weight trends FEATURES - Log by chatting: Just send the AI a quick message. No forms, no searching a food database. - Log with a photo: Snap your meal and the AI estimates the contents, portions, calories and macros. - Your personal AI food coach: Ask "What should I have for lunch?" or "Help me pick from this menu" and get concrete suggestions, plus advice for tomorrow. - Eating out or grabbing convenience food? Send a photo of the menu and the AI helps you choose. - Built to keep you going: Kind check-ins that celebrate your wins, with easy-to-read charts of your weight, calories and macros. MAIN FUNCTIONS - Calorie logging by simple chat messages - Photo-based meal logging - Automatic calculation of calories and macros (protein, fat, carbs) - Remaining calories for the day at a glance - AI meal and menu suggestions - Weight and body-fat tracking with charts - Automatic calorie goal setting OUR PHILOSOPHY A diet shouldn't be a series of sacrifices or a race against numbers. You don't have to be perfect - what matters is being able to keep going. Diet AI feels like checking in with a kind coach every day, supporting a pace you can actually sustain. Start by telling the AI about your next meal. Note: This app supports building healthy eating habits and is not intended for medical diagnosis or treatment.
