See your facial expressions change on camera.
Your video stays on this device. The first start downloads the face models and browser runtime.
Smoothing steadies the live scores. Turn it off to see brief or fast expressions as they happen. Scores may jump more.
The camera and live scores can keep running while you’re away, along with any active recording. Your browser may slow or suspend them.
Live expression scores
Scores describe visible expressions. How you feel may differ.

Personalize scores
Teach the app how you normally look on camera. Use your usual seat, lighting, webcam placement, and appearance, even if your webcam sits low or you have a full beard.
Start the camera, then choose Teach Neutral. Look at the screen and relax your brow, eyes, and mouth. After the countdown, hold still for about three seconds. This saves your relaxed expression and a reference for your usual head angle.
Then teach another expression so the app can distinguish your examples. Retake Neutral if you change your camera or usual position. Only numeric examples and the reference are saved in this browser.

Camera tip. Use even front lighting, keep your face about a third of the frame, and avoid strong backlight.
