Make sense of a Nutrition Facts panel in one photo. Nutrition Label Reader reads the core Nutrition Facts lines (calories, fats, cholesterol, sodium, carbohydrates, fiber, sugars and protein) as printed, then adds what the label leaves unsaid: each nutrient's percent Daily Value and a High / Medium / Low level based on official FDA reference values.

How it works

  1. Photograph the black-and-white panel straight on, filling the frame.
  2. Each core line comes back with its value and unit. A line that isn't on the label is shown as not listed, never guessed. Amounts printed as "less than" (such as "<1 g") are shown at that upper bound (1 g).
  3. The Daily Value percentages and High / Medium / Low levels are computed by fixed arithmetic from FDA reference values, not by the AI — the same panel always grades the same way.

Reading the levels

  • High means 20% or more of the Daily Value per serving.
  • Medium is 6–19%.
  • Low is 5% or less.
  • For dietary fiber the levels read the other way round: more is better.
  • Panels stated per 100 g are listed without levels — the cutoffs assume a per-serving basis.

What it won't do

It reads the core lines listed above; vitamins and minerals (vitamin D, calcium, iron, potassium and any others on the panel) are not read. It doesn't judge whether the food is healthy for you, and it doesn't handle labels from countries whose panels differ fundamentally from the US format. Values are extracted, not verified against the product — if the label photo is blurry, confirm anything that matters.

Questions

Are the High / Medium / Low levels made up by the AI?

No. The AI only extracts what is printed on the panel. The percentages and levels come from fixed arithmetic against FDA Daily Value reference values, computed by a deterministic step — the same numbers always produce the same grade.

What does "percent Daily Value" mean?

It's the share of the recommended daily amount of a nutrient that one serving provides. 20% or more is conventionally High, 5% or less is Low — the tool applies exactly that convention. Panels stated per 100 g are read and listed too, but without Daily Value levels, since the cutoffs assume a per-serving basis.

It said my photo is not a label — why?

The tool needs the actual Nutrition Facts panel (the black-and-white table). A product shot, an ingredient list, or a panel at a steep angle gets a short explanation of what to fix instead of a reading. Shoot the panel straight on, fill the frame, avoid glare, and run it again.

What happens to my photo?

It is used to produce your reading and stays with your task history.

Does it read vitamins and minerals?

No. It reads the core lines: calories, total and saturated fat, trans fat, cholesterol, sodium, total carbohydrate, dietary fiber, total and added sugars, and protein. Vitamin D, calcium, iron, potassium and any other vitamins or minerals on the panel are left out.
