Photo Calorie Counter: Snap a Meal and Estimate Calories
Point your camera at a meal and let AI do the counting. Here is exactly what happens between taking the photo and the entry landing in your food diary.
1. Take a photo
Open the camera from the Log button and photograph your plate. A single top-down shot that shows the whole meal generally works best, but SnapKai does not require any particular lighting setup or a special angle.
2. AI identifies the food
The photo is sent for AI analysis, which identifies the individual foods on the plate and estimates how much of each is there. This uses credits, refunded automatically if the AI cannot make sense of the photo.
3. Review calories and macros
The result screen breaks the meal down into calories, protein, carbohydrate and fat, with a confidence indicator next to the estimate. Nothing here has been saved yet.
4. Edit before saving
This is where SnapKai differs from a pure guess-and-log tool: rescale the portion with a slider, rename or remove an item, or add something the AI missed. Only when you confirm does the entry reach your diary.
5. Understand the limitations
A photo cannot always reveal hidden oils, the exact ingredients in a sauce, precise serving weights, or the cooking method used. Camera angle affects the estimate too. SnapKai does not hide this: every estimate is labelled as an estimate, with its confidence shown, and you can always edit or reject a result you do not trust.
When to use a photo, and when to scan instead
A photo calorie counter is the fastest way to log a home-cooked meal or a restaurant plate where there is no label to scan. For packaged food, a nutrition label scan or a free barcode scan gives a more precise result, because it reads printed numbers instead of estimating from an image.

Photo calorie counter: frequently asked questions
A meal photo scan uses credits, and new accounts get 30 credits free. A scan that fails or returns nothing useful is refunded automatically.
You can edit the result before saving: add a missing item, remove one that shouldn't be there, or rescale the whole plate with a slider. Nothing reaches your diary until you confirm it.
A photo-based estimate depends on portion size, angle and lighting, so small variations are normal. That is exactly why every result shows a confidence indicator and stays editable rather than being presented as an exact measurement.
Yes. Packaged food is more precisely logged with a nutrition label scan or a free barcode scan, both of which read printed values instead of estimating from an image.
