Introduction

What you eat is information.
We just learned to read it.

F or two years we trained a model on tens of thousands of medically-referenced foods, then taught it to look at a single photograph and resolve the dish into grams of carbohydrate, calories, glycemic load, and the reasoning behind every number. CalEye is what came out — a pocket-sized clinician for carbs, calories, and the long arc of metabolic health. No bar codes. No log books. No friction between eating and understanding what just happened to your body.

Three frames. One answer.

Point. Read. Calibrate. CalEye resolves a meal in under a second — and shows you why the number is the number.

For diabetics

Glycemic load, without the spreadsheet.

If you live with diabetes, the question is rarely "how many calories" and almost always "what's this going to do to my sugar". CalEye answers in glycemic-load units, not vague color codes, and shows the science behind every estimate. Your endocrinologist will recognize the sources.

For weight loss

Calories without the log book.

If you're chasing a body composition goal, the bottleneck isn't motivation — it's friction. CalEye removes the log-book entirely: photograph, eat, the numbers are already on your phone. The first week feels weirdly empty. That's the point.

Cited from the same sources
your endocrinologist reads.

The model resolves portion-size estimation in a way I haven't seen open-sourced before. The fact that the citation surfaces inline with the macros is the part I'd want my patients to see.

The Method

How the AI thinks.

Six stages, hairline-connected. CalEye doesn't guess — it reasons.

  1. 01SegmentationEach dish on the plate isolated as its own region.
  2. 02IdentificationMatch the region against a medically-referenced food set.
  3. 03PortionEstimate weight from on-plate scale cues.
  4. 04MacrosResolve carbs, fat, protein per 100 g.
  5. 05Glycemic loadCross-reference to glycemic index tables.
  6. 06CitationSurface the underlying source inline.

In practice

What changed when they started reading.

I stopped guessing carbs at dinner. My A1C dropped from 7.9 to 6.4 in five months. My endocrinologist asked for screenshots.

As a clinician, what I want from a patient-facing tool is that it doesn't lie about uncertainty. This one cites its sources.
