AI Features

Smarter tracking, not more work

Most calorie trackers make you search for every food, one by one. CalorieDetails uses AI to eliminate the tedious parts — so you spend less time logging and more time making progress.

🗣️
Natural Language Meal Logging

Describe your meal the way you'd tell a friend — "a chicken burrito bowl with rice, black beans, and sour cream" — and AI logs every item automatically. No searching, no clicking through dropdown menus.

🧠
Automatic Food Database Expansion

If a food isn't in our 350,000+ item database, AI looks up its nutrition data and adds it automatically. The database grows smarter with every search, so future lookups are instant.

Common Questions

Frequently asked questions

CalorieDetails uses AI in three key ways. First, natural language meal logging — describe your meal in plain English and AI parses it into individual foods and logs them. Second, daily nutrition analysis — after logging your meals, AI reviews your full day and gives personalised feedback on calories, protein, key nutrients, and specific suggestions. Third, per-food and per-exercise coaching — every food and exercise page has a built-in AI coach you can ask questions directly. All of these features are completely free.
Yes — completely free, forever. There is no premium plan, no credit card required, and no usage limits on the core tracking and AI features. CalorieDetails is supported by advertising, not subscriptions. Creating an account takes 30 seconds and gives you full access to all features immediately.
Open the Food Tracker and tap the "Log with AI" button. Select your meal type (breakfast, lunch, dinner, or snack), then type what you ate in plain English — for example, "two scrambled eggs with toast and a glass of orange juice". AI parses this into individual food items, searches our database of 350,000+ foods for each one, and shows you the matches. If a food isn't in our database, AI automatically adds it with accurate nutrition data. Review the matches, confirm, and all foods are logged in one tap.
After logging your meals for the day, tap the "Analyse My Day with AI" button on the Food Tracker. You can optionally enter your daily calorie target (or leave it blank to use the 2,000 calorie default). AI then reviews your complete food log and provides: an overall calorie assessment against your target, a protein evaluation, one key nutrient observation (high sodium, low fiber, etc.), and two specific actionable suggestions. You can also ask up to three follow-up questions about your nutrition.
No app download is required. CalorieDetails is a web application that works in any browser on desktop and mobile. Simply visit caloriedetails.com, create a free account, and start tracking. The site is fully responsive and works well on smartphones.
Our primary food database uses USDA Food Central data — the most authoritative nutrition database available. When AI adds a new food that isn't in the USDA database, it uses its training knowledge to estimate nutrition values, and these entries are clearly labelled as AI estimates. For packaged and branded foods, AI estimates are generally accurate but we always recommend verifying with the product label for precise tracking.
