How it works

Everything happens live in the browser tab. No account, no download, no upload.

  1. Allow the camera

    Open the camera page and allow access. The hand tracking model loads once and is cached.

  2. Make a hand sign

    21 points on each hand are tracked and matched against the shape of every gesture, many times a second.

  3. Watch the effect

    Each gesture triggers its own effect, drawn on top of your video. Record a clip to keep it.

Why people use it

Two hands at once

Each hand gets its own gesture and effect, and heart hands or a double palm join both hands into one.

Private by design

Recognition runs on your device. Your video is never uploaded. Read how.

Works offline

After the first visit the app and model are cached, so it keeps working without a connection.

Record clips

Capture the camera view with the effects as a video file, saved straight to your device.

Code view on desktop

On a computer, the camera sits in a code editor layout with the live source, landmarks and tracker log.

Demo without a camera

No webcam? Watch the demo: animated hands run through the same recognizer and effects.
