How a photo becomes a number.
01 · Detect
Detect
A vision model identifies the foods on the plate. "Grilled chicken, white rice, broccoli."
02 · Estimate portion
Estimate portion
Plate scale, utensil cues, and visual volume become grams per food. The hardest step.
03 · Look up nutrition
Look up nutrition
Grams × USDA FoodData Central values. Plain arithmetic, not a guess.
Photo tips
What makes a good photo.
You don't need food-blog lighting. You need a photo that lets the model see the food.
do
Plate centered, top-down or 45°
avoid
Side-on shot that hides depth
do
Most foods visible (stir if needed)
avoid
Everything hidden under sauce
do
One frame, one meal
avoid
Breakfast + lunch + coffee in one shot
do
Daylight or normal room light
avoid
Total darkness or hard backlight
Strengths and weaknesses
Where the photo flow wins.
Wins
- · Restaurant meals at known chains
- · Home stir-fries, pastas, salads, rice bowls
- · Sharing plates (snap before eating, adjust to half)
- · Snacks small enough that you'd normally skip logging
Less reliable
- · Mixed soups and stews (hidden ingredients)
- · Buffet plates with many small items
- · Foods where prep varies a lot (fried chicken oil)
For these, type the meal name and add a one-line detail. The text flow handles it well.
AI photo calorie counter · FAQ
Questions, answered.
Our benchmark target is within 8% of a registered dietitian on average, with median error under 5% on common meals. Peer-reviewed research puts mainstream AI photo calorie estimation in the 5 to 15% range, which is roughly the same band as a dietitian eyeballing the same plate.
