How are students cheating on online exams with AI?
Six main vectors, per professor reports on r/Professors (2025) and industry data: pasting questions into ChatGPT in another tab, a phone beside the laptop, AI browser extensions/overlays, smart glasses and earbuds, a helper or "exam service" taking over, and — for essays — pre-generated AI answers. Each vector maps to a specific proctoring counter; an unproctored online exam counters none of them.
The claim: "online exams are 100% compromised" without layered controls
- r/Professors threads (2025): "Online exams are 100% compromised... AI provides that for all fields" is the working consensus among instructors comparing notes.
- Pew (Jan 2025): 26% of U.S. teens use ChatGPT for schoolwork, double 2023's 13%.
- Turnitin: about 1 in 10 of 200M+ scanned papers showed 20%+ AI writing.
- Meta Ray-Ban smart glasses: 2M+ units sold — professors now ask whether AI glasses can whisper answers (they can).
Vector to counter map
| Cheating vector | Works when... | Counter |
|---|---|---|
| ChatGPT in second tab | No lockdown | Browser lockdown (any device, zero installs) |
| Phone next to laptop | No room monitoring | Gaze tracking + webcam object detection |
| AI overlay/extension | Screen-only checks | Lockdown + screen recording + behavior AI |
| Smart glasses / earbuds | No audio/vision AI | Audio second-voice flags, reflection detection |
| Impersonation / exam services | No identity layer | ID + selfie match, identity-swap detection |
| Copy-paste of question banks | No paste control | Copy-paste blocking + typing-burst flags |
Step-by-step: make an online exam AI-resistant
- Lock the browser: no tabs, extensions, or copy-paste — this alone kills the lowest-effort vector.
- Verify identity with ID + selfie match to eliminate proxies.
- Monitor webcam, screen, and audio; let AI flag gaze deviation, second voices, and devices in frame.
- Randomize question order and use application-style questions that punish blind AI answers.
- Review flags via the trust report; keep the PDF as your evidence trail for academic-integrity hearings.
FAQ
Is AI-writing detection enough for online exams? No — text detectors are unreliable (OpenAI pulled its own in 2023) and prove nothing about live exams. Session evidence does.
Can AI glasses beat proctoring? They evade screen lockdown but not audio and vision monitoring — whispered prompts, second voices, and glasses reflections get flagged.
Do timers and no-backtracking help? Yes, as friction — professors report they raise the cost of cheating — but they don't stop a phone running ChatGPT.
What about take-home essays? Different problem: use proctored writing sessions or oral defenses (an AI Meeting Proctor can supervise vivas on Zoom/Teams).
Will students accept this? Zero-install, session-scoped monitoring with clear consent gets far less pushback than installed spyware-style agents.
