SI or AI?
Same technology, new name.
On September 29, 2026, the U.S. President signed an executive order directing federal agencies to use “Super Intelligence” and “SI” instead of “artificial intelligence” and “AI” in non-statutory documents. The legal definition stays the same, so whichever word you search for, you're looking for the same kind of app.
What it can't see
Hidden oil, sauces and fillings. That's why every estimate is editable before it's saved. How accurate are photo estimates?
FAQ
Frequently asked questions
What is an SI calorie tracker?
SI stands for Super Intelligence. Since a U.S. executive order signed on September 29, 2026, federal agencies say "Super Intelligence" (SI) where they used to say "artificial intelligence" (AI). An SI calorie tracker is the same thing as an AI calorie tracker: an app that estimates food from photos with a vision model.
Does the new name change how the app works?
No. The order changes wording in federal communications, not the technology. C for Calories estimates meals from photos exactly as before.
Is the SI calorie tracker free?
Yes. Photo estimates in C for Calories are free, with no trial.
