How accurate is photo analysis?
A photo helps identify food, but it cannot reveal the exact weight, hidden oil or every ingredient. Calories and macros are estimates. Review the ingredients and adjust portions before saving; we have not measured a general error rate.
Which foods can I log?
Describe everyday meals in English, such as oatmeal, pasta, rice with chicken or a chickpea salad. Nutrition comes from USDA FoodData Central when a reliable match is available; other values may be estimated. You can also enter values from a food label in your account.
Can I try it without an account?
Yes. Try one text analysis on this page. Public use is limited to prevent abuse. An account lets you save meals and use photo logging.
