SnapDust
Snap your fingers on a Google Meet call and crumble into dust. Snap again and fly back together in a swirl of gold.
A Chrome extension. Everything runs on your computer: nothing is recorded or sent anywhere (privacy policy).
Use it
- Install SnapDust and open (or reload) a Google Meet tab with your camera on.
- Click the SnapDust icon, then Capture empty room, and step aside for a few seconds so it can see the room behind you.
- Hold your hand up, thumb and middle finger together, and snap. You turn to dust.
- Snap again to come back.
There are also Vanish / Capture buttons in the popup and keyboard shortcuts: ⌥⇧V (Alt+Shift+V) and ⌥⇧B.
Settings
- Detect by. Sound + hand (default) needs both the snap's sound and your hand in snap pose, so typing and talking don't set it off. Sound only works with your hand out of shot. Hand only doesn't use the microphone.
- Sensitivity. Raise it if quiet snaps are missed, lower it if other clicks trigger it.
- Who vanishes (under More). Just me (default) vanishes the person nearest the camera; Everyone in frame vanishes everyone.
Good to know
- To hear snaps while you're muted in Meet, SnapDust keeps listening to Meet's microphone, so your mic indicator can stay on. Choose Hand only to avoid this.
- If you move the camera or the lighting changes a lot, capture the room again.
- Two people touching in the picture count as one.
- Only Google Meet in desktop Chrome.
