FAQ
How does Prefit.AI count calories from a photo?
An AI vision model identifies each food on your plate, estimates portion sizes from visual cues like plate size and utensils, and adds likely hidden calories such as cooking oil and dressings.
How accurate are the estimates?
Photo-based estimates are typically within 20% for simple meals and less precise for mixed dishes. Adding a note such as “large portion” or “no dressing” improves accuracy. It is not medical advice.
Do I need an account?
No. Open the page, take a photo and get your result. There is no sign-up and nothing to install.
Are my photos stored?
Prefit.AI does not save your photos. Each photo is sent to the AI model only to produce your estimate.
