Proctortrack vs Proctorio - Which Watches More on Mac?

Proctortrack and Proctorio are the two browser-extension proctoring platforms most US universities pick when they want automated proctoring without paying for live agents. They look similar on paper but the monitoring intensity differs noticeably.

Proctorio takes a "broad and shallow" approach: webcam frames every few seconds, basic face detection, ambient audio sampling, screen capture during the exam, plus a behavior-anomaly score the instructor reviews. Proctortrack goes deeper with continuous biometric verification: every frame compared against your enrolled baseline, voice patterns checked for the same speaker, and integration with the institution's identity system. Both stacks capture the screen through Chrome's tab-capture path on Mac, both go through ScreenCaptureKit, both filter out flagged windows. The deeper biometric layer in Proctortrack does not see the screen, so the overlay's invisibility is identical.

Voice ID checks that the speaker is you, not whether you're reading something. The overlay makes no sound; voice ID only hears the room and your voice.

It checks face presence and counts faces in frame. It does not deeply biometric-match each frame, which is the contrast with Proctortrack.

Both are equally invisible to the overlay. Difficulty depends on your camera setup, room, and behavior, not on which proctor you face.
