Photograph your plate
Point your phone camera at a meal. No special lighting or angle is required, though a clear top-down shot helps the AI see everything on the plate.
AI meal photo logging
Track Calories and Macros from a Photo
Instead of searching a food database and guessing at a serving size, take a photo of your meal. SnapKai's AI identifies what's on the plate and estimates calories, protein, carbs and fat, with the result yours to check before it counts.
From plate to logged entry
AI identifies the foods
The AI recognises the visible foods and estimates their portions, then works out calories, protein, carbohydrate and fat for the plate as a whole.
Confidence is shown
Every estimate carries a confidence indicator rather than pretending to be exact. A photo is a guess about portion size, and SnapKai says so.
You review before it counts
The result lands on an editable confirmation screen. Adjust the portion, rename or remove an item, or scale the whole plate before anything is saved.
Failed scans are refunded
If the AI cannot make sense of the photo, or you reject the result as useless, the credits it cost are refunded automatically.
Honest about what a photo can and cannot see
A camera cannot see the oil a dish was fried in, the exact weight of a serving, or every sauce mixed through a meal. SnapKai's approach is to label estimates as estimates, show a confidence level for each one, and put you in charge of the final number rather than pretending a photo is a set of kitchen scales. Read the full breakdown on how accurate AI calorie trackers are.
For packaged food where exact numbers matter, a nutrition label scan or a free barcode scan reads the printed values directly instead of estimating from a photo.
Meal photos are processed, then discarded
Your meal photo is used to identify the food and then discarded. It is not stored on SnapKai's servers and is not used to train AI models without your explicit opt-in. What stays is the food log entry you confirmed. See the privacy and AI page for the full plain-language explanation, and the barcode calorie scanner page for how the shared food database works.
AI calorie tracker: frequently asked questions
SnapKai's AI looks at a meal photo, identifies the foods it can see, estimates their portion sizes, and calculates calories, protein, carbohydrate and fat from those estimates. It shows a confidence level for the result and lets you edit anything before it is saved to your diary.
No, and SnapKai does not claim it is. A camera cannot see hidden oils, sauces mixed through a dish, or the exact weight of a serving, so a photo estimate carries meaningful uncertainty. That is why every estimate is labelled as an estimate with a confidence indicator. Weighing food, or scanning a nutrition label or barcode, is more precise. See the accuracy page for the full explanation.
A meal photo scan uses credits, and new accounts start with 30 free credits. If a scan fails or returns nothing useful, the credit is refunded automatically.
Yes. Every AI result opens on an editable review screen before it touches your log. You can rescale the portion with a slider, rename or remove individual items, or reject the result entirely, in which case the credit comes back.
