Real-time object detection that runs in your browser

This free app finds and tracks objects in your webcam feed or in a video file, live. The AI model (YOLO26 or YOLOE) runs on your own graphics card through WebGPU and ONNX Runtime Web, so there is no server, no account and no install, and your video never leaves your device.

How it works

  1. Pick a source: your camera, or upload a video (for example traffic footage).
  2. Detect: the model finds objects in each frame on your GPU.
  3. Track: each object gets a stable ID (like car #12) and its box glides with it between frames.
  4. Tune: switch between Fast, Accurate and More objects, and set the minimum confidence.

Frequently asked questions

Is it free?

Yes. It is free and open source (Apache-2.0). There is no account, no install and no usage limit, because everything runs on your own device.

Is my camera or video uploaded anywhere?

No. Video frames are processed by the AI model inside your browser, on your own GPU, and are never sent to a server. The site only counts anonymous page views.

Which browsers and devices does it work on?

It works best in Chrome or Edge 113 or newer on a laptop or desktop, using WebGPU. Firefox and Safari use a slower WebAssembly fallback. Camera access requires HTTPS, which this site uses.

How accurate and fast is it?

On 500 COCO val2017 test images, the Accurate mode (YOLO26s) scores 0.475 mAP and the Fast mode (YOLO26n) 0.380 mAP. On a laptop with integrated graphics, Fast processes 7 to 8 frames per second, and boxes are redrawn at about 60 FPS in between.

Can it detect a smartwatch, glasses or keys?

Yes, in the More objects mode. It uses an open-vocabulary YOLOE model with 268 everyday object classes, including smartwatch, glasses, earbuds, keys and wallet. The Fast and Accurate modes detect the 80 standard COCO classes.

Can I use it on traffic or other videos?

Yes. Click Upload video to run detection on a video file from your device. Each car or person gets a stable tracking ID and its box follows it as it moves. The video never leaves your device.
