Frequently Asked Questions
How accurate are the calorie estimates?
Calorie Estimate uses GPT-4o, one of the most capable AI models available. Estimates are typically within 10–20% of actual values. For best results, provide a clear photo or a detailed description — for example, 'grilled chicken breast, 200 g, with steamed broccoli'.
Is my food data private?
Yes. All meal logs are stored exclusively in your browser's local storage — nothing is sent to a server or saved to an account. Your nutrition history never leaves your device.
What are macros and why should I track them?
Macronutrients (macros) are protein, carbohydrates, and fat — the three nutrients that make up the caloric content of food. Tracking them helps you manage body composition, meet fitness goals, and ensure balanced nutrition beyond just counting calories.
What is the Takeout Advisor?
The Takeout Advisor is an AI chat assistant that knows your remaining macro budget for the day and suggests restaurant or takeout meals that align with your goals. Ask it what to order at any type of cuisine and it gives you specific, macro-aware recommendations.
Does it work on mobile?
Yes. Calorie Estimate is fully responsive and works on any device. On mobile, you can use your camera directly to snap a meal photo and get an instant nutritional analysis.
