AI Overlay for Examus Proctoring on Mac

Examus is a browser-based AI-proctoring service that reaches across the EU, the UK, and Russia/CIS markets. It is a pure-cloud product: a Chrome or Firefox extension plus a server-side AI for review, with optional live proctors.

Examus does not ship a desktop app on macOS, which keeps its capture surface entirely inside the browser sandbox. The extension calls navigator.mediaDevices.getDisplayMedia for the screen and getUserMedia for camera and microphone. Apple's WebKit and Chromium ports of those APIs both consult the same window-privacy table the OS maintains. Fracture sets the flag on its window, so the captured stream never contains the overlay. The audio and webcam tracks are unrelated and behave normally.

Yes - macOS prompts you to grant it when the exam starts. Grant it; the system still respects per-window privacy regardless of the permission state.

No. The overlay is missing from frames; the surrounding pixels are captured exactly as if the overlay never existed.

Only if you actually plug in an external monitor. The overlay is a window on your existing display, not a separate display.
