Proctorio vs LockDown Browser on Mac - AI-Heavy vs Conservative
Architecture comparison
| Aspect | Proctorio | LockDown Browser |
|---|---|---|
| Install | Chrome extension | Native macOS app |
| Apple Silicon | N/A (extension) | Native arm64 |
| AI behavior analysis | Heavy - gaze, head pose, audio, abnormality scoring | Lighter - face presence, audio anomaly |
| Kiosk mode | Chrome-tab kiosk | Native app kiosk |
| Vendor | Proctorio Inc. | Respondus |
Privacy invasiveness comparison
Proctorio is consistently cited as the most invasive in 2022-2025 academic literature. Specific differences:
| Capability | Proctorio | LDB + Monitor |
|---|---|---|
| Eye-gaze tracking (where you look) | Yes | No |
| Head pose tracking | Yes | Limited |
| Behavioral abnormality scoring | Yes - composite "suspicious" score across many signals | Limited (face presence, audio) |
| Phone detection | Audio + visual | Audio mostly |
| Multiple-faces flagging | Yes | Yes |
| Post-exam human review | Optional (institution-configured) | Standard |
Performance on Mac (M2 Air, 90-min)
- Proctorio: Chrome + extension + heavy AI. ~18% CPU sustained, ~17% battery/hr (Chrome dominates).
- LDB + Monitor: ~17% CPU, ~10% battery/hr.
Proctorio's heavy AI is the differentiator - gaze tracking alone is GPU-intensive on Mac. Battery cost is significantly higher.
Accessibility critique
Proctorio has been the focus of multiple academic studies documenting:
- Disparate face-detection accuracy on darker skin tones (multiple peer-reviewed studies 2021-2023).
- Disparate flag rates for students with various disabilities (autism, ADHD, vision impairment).
- Stress / anxiety induced by gaze-tracking and abnormality scoring.
Several universities have phased out Proctorio specifically; some replaced it with LDB+Monitor or in-person alternatives.
Flag rates (instructor reviewing experience)
| Tool | % sessions flagged for review (typical) |
|---|---|
| Proctorio | ~30-40% (AI flags many sessions) |
| LDB + Monitor | ~10-15% (more conservative) |
| Honorlock | ~25-30% |
| Examplify | ~10-15% |
Higher flag rate ≠ more cheating - usually false positives. Instructors must review flagged sessions, which is high-volume work with Proctorio.
Student experience
- Proctorio: stressful for many students. Knowing that gaze/head/movement is being scored makes natural exam-taking behaviors look "suspicious" to AI.
- LDB + Monitor: less behavioral surveillance feel; more like a webcam recording for human review.
If your university uses Proctorio
- You typically have no opt-out short of disability accommodations.
- Test your setup with the practice exam - the high flag rate means you want to know what triggers it before the real exam.
- Document any accessibility concerns with your disability office BEFORE the exam.
- If you have ADHD / autism / similar diagnoses where natural exam behavior may trigger flags, request an accommodation.
If you can choose between LDB and Proctorio
Most students prefer LDB+Monitor over Proctorio for these reasons:
- Less stress during exam.
- Lower battery cost.
- More predictable Mac install + launch.
- Better accessibility track record.
Frequently asked questions
Why does Proctorio flag me when I look away to think?
Proctorio's gaze-tracking AI scores looking away from screen as "suspicious". The flag isn't a violation; it's a flag for human review. Instructors typically recognize natural thinking as benign.
Can I disable Proctorio's eye tracking?
No - it's built into the AI behavioral analysis. The institution can configure which signals to use, but you as a student can't.
Is Proctorio still aggressively used in 2026?
Yes, but with declining market share. Several universities have phased it out specifically; others continue to use it. Trend is toward less invasive tools.
Will Proctorio detect me looking at my phone?
It tries - both audio (if you tap on a phone) and visual (camera frame). Detection rate is high but not perfect. The point: don't use a phone during a Proctorio exam.
