CLOAK
Invisible interview copilot

They can't see
what isn't there.

Cloak floats an AI copilot above your screen during any call — and it stays completely invisible to Zoom, Google Meet, Teams, and every recorder. Quiet, precise, gone the moment they look.

The vanishing act

On your screen. Gone from theirs.

The same moment, two views. Cloak sits right in front of you while you share your screen — yet the capture stream never sees it.

Cloak stays out of the capture stream entirely — invisible to Zoom, Google Meet, Teams, OBS, and QuickTime, every single time.

Built for stealth

Quiet by design.

CLOAK

Invisible to capture

Screen sharing and recording apps capture everything on your screen — except Cloak. It simply never appears in the stream.
