Free Offline AI
Calorie Tracker
Drop in a photo of your meal. An AI model running inside your browser names the food and estimates calories, protein, carbs, and fat, without uploading your photo anywhere. Internet is only needed to load the page and download the model once. Works best on desktop.
No upload · No account · Free forever
Loading the scanner… If it doesn't appear, your browser may not support it. The ProTrack AI iPhone app runs the same scanner natively.
You're on a phone. Here's a better way
This browser tool needs a desktop computer to run its 320 MB AI model. On iPhone, the ProTrack AI app runs the same scanner natively: faster, fully offline, with meal history and daily goals.

How it works
Photo in, calories out. Nothing in between.
Most photo calorie counters send your food pics to a server. This one can't. The AI itself moves to your browser instead.
The AI model loads once
On your first scan, your browser downloads the vision model (~320 MB) and stores it locally. Every scan after that starts instantly.
Your photo stays put
Drop in any meal photo: drag and drop, browse, or paste a screenshot. It's resized and analyzed right on your device. No upload happens, so there's nothing for a server to keep.
Calories & macros appear
The AI names the visible meal and estimates calories, protein, carbs, and fat for the portion shown. If it misjudged something, add a correction and re-analyze.
Privacy
Your food photos never leave this device
This isn't a privacy policy. It's an architecture. The analysis happens in your browser, so uploading your photo is not something we chose not to do. It's something this tool cannot do.
- Processed on your device. The photo is analyzed by an AI model running in your browser, not on a server.
- Internet needed only once. To load the page and download the model on first use. After that, airplane mode works fine.
- Nothing is stored. Photos and results live only in the open tab. Close it, and they're gone. Only the model file is cached, so you don't re-download it.
- Same model as the app. It's the exact AI model inside ProTrack AI for iPhone. The whole product works this way.
From tool to habit
Like the scanner? It lives on your iPhone.

FAQ
Calorie scanner questions
What is the free offline AI calorie tracker?
It's a free web tool from ProTrack AI that estimates the food name, calories, protein, carbs, and fat from a photo of your meal. The AI vision model runs entirely inside your browser, so your photo is analyzed on your device and never uploaded to a server.
Is my food photo uploaded anywhere?
No. Your photo is processed on your device by an AI model running in your browser. It's never uploaded, stored, or shared. An internet connection is only needed to load the page and download the AI model the first time you scan.
How accurate are the calorie estimates?
The AI estimates nutrition from a single photo of the visible portion, so results are estimates, not lab measurements. Accuracy depends on lighting, angle, and how visible the food is. If something looks off, add a correction (like "about 200g, grilled not fried") and re-analyze. Estimates are for personal tracking and are not medical advice.
Why does the tool download a ~320 MB AI model?
Analyzing photos locally means the AI itself, a 450-million-parameter vision model, has to live on your device instead of on a server. It downloads once, your browser stores it, and every later scan starts instantly. That download is the price of your photos staying private.
Does the calorie scanner work offline?
Yes. Once the page is open and the model is downloaded, analysis runs locally and works without an internet connection. Turn on airplane mode and keep scanning. It's a good way to verify the privacy claim yourself.
Which browsers and computers does it support?
Modern desktop browsers: Chrome, Edge, Safari, and Firefox on a computer with roughly 8 GB of RAM or more. Browsers with WebGPU (recent Chrome and Edge) analyze photos noticeably faster. On slower machines the scan still works, it just takes longer.
Can I use it on my iPhone or Android phone?
The browser tool is designed for desktop computers because of the model size. On iPhone, the ProTrack AI app runs the same photo scanner natively: faster, fully offline, with meal history, daily goals, and a barcode scanner.
Is the tool really free? What's the catch?
The web scanner is completely free: no account, no sign-up, no scan limit, and no processing of your data (we couldn't, it never reaches us). We built it to show how private on-device food scanning works. If you find yourself wanting this every day, that's what the iPhone app is for.
