AI Overlay for ProctorEdu on Mac
ProctorEdu is a cloud-based proctoring system used in EU universities and corporate certification programs. It supports automated, live, and hybrid review modes, all delivered through a browser extension.
ProctorEdu's extension intercepts WebRTC calls to record screen, webcam, and audio simultaneously. The recordings go to ProctorEdu's cloud where ML evaluates each minute for behavior anomalies; live human proctors can join during the session. macOS' WebRTC implementation queries the OS window list with the privacy flag respected, so the live proctor view, the recording, and the post-hoc ML pass all see the same filtered frames - frames that do not contain the LDBypass window.
Key points
- ProctorEdu supports "verification only" (ID + room scan) and "full proctoring" modes; the overlay's invisibility is identical for both.
- Live proctor mode adds a small picture-in-picture from your webcam onto the proctor side; it does not change what your screen capture contains.
- The mobile companion app (ProctorEdu Smart) records you from a second angle; close the overlay if you cannot trust your phone framing.
- Russian-language and English deployments share the same engine; behavior is identical.

Common questions
What if my exam requires the ProctorEdu mobile companion?
The phone records the room from outside the laptop. It is a physical camera and sees physical pixels. The overlay's privacy flag does not protect against an external camera.
Does ProctorEdu detect screen recorders?
It detects active screen-recording processes by name. LDBypass is not a screen recorder and runs under a randomized innocuous bundle ID.
Will the overlay affect my microphone audio?
No. The overlay does not use the microphone. ProctorEdu's audio analysis hears only the room and your voice, unchanged.
