AI proctoring for remote team assessment_
Cheating doesn’t show up in a score. Codility layers behavioral, similarity, identity and network signals into one risk level on every candidate report, and your reviewers see the evidence underneath.
87% of candidates rate their experience good or excellent, across 48,000+ post-assessment responses.

Paste detection was built for a quieter problem
“I need live proctoring. How do I know if a candidate is using an invisible AI overlay?”
That’s a real review of our own platform, left in 2025. It’s now the most common question buyers bring us.
The gap is evidence. When a score is questioned, your team needs to see how the work was produced.
Paste detection catches a paste. It does not catch a candidate retyping an AI answer line by line from a second screen. Codility offers pattern detection exactly for this problem.
Screen sharing shows you the screen. Tools like Cluely and Interview Coder are excluded from screen capture, so the screen looks clean.
Session recording gives you footage that is difficult to watch at scale. An hour of video per candidate does not scale past a handful of roles.
Exam proctoring platforms were built to monitor a room for universities and certification bodies. They cannot tell you how a piece of code came to exist.
Integrity signals, assembled into something a person can review
Integrity is built into Screen, Interview and Skills Intelligence. Behavioral events, code history, similarity matches, identity checks and network checks feed a single risk level on every candidate report: none, low, moderate or high. Plus pattern detection and invisible AI overlay detection.
Your reviewer opens the level, sees which categories contributed, and drills into the evidence underneath. Codility shows its work. Your reviewer makes the call.
See how the code was written, keystroke by keystroke
Open the Code Evolution Chart and you replay the session as a timeline. Typing bursts, paste events, focus changes and sudden large insertions all sit on the same line, so your reviewer watches the solution take shape.
A 60-minute session becomes reviewable in a couple of minutes.

One risk level instead of a wall of flags
Integrity Risk gives you one risk level across behavioral events, cross-candidate similarity, identity verification status and network checks: none, low, moderate or high. A confirmed similarity match raises it automatically.
- Deterministic rules produce it, so the same inputs always give the same result.
Your team reviews the sessions that warrant it rather than all of them
Catch the tools that hide from screen sharing
AI overlay apps show candidates answers in a window that screen sharing never picks up. The Codility App, a lightweight desktop app for macOS and Windows, catches those tools on the candidate’s device during the assessment and flags them on the candidate report.
- Candidates take the assessment inside the Codility App, so the check runs on their device, not just in the browser.
- The app watches for any program that asks to be hidden from screen capture. Overlay tools can’t stay hidden without that request.
- So the check still works on tools sold as “undetectable.”
- It checks the device only. It doesn’t record the screen or log keystrokes.
- You turn it on per assessment, so candidates only install it where the stakes justify it.

What AI proctoring can and cannot tell you
No proctoring setup catches everything, ours included.
| What a candidate might do | What Codility catches in the browser | What the Codility App adds (optional) |
|---|---|---|
| Pastes an answer in | The paste event, where it landed in the timeline, and how large it was | Already covered |
| Retypes an AI answer from a second screen | Typing Pattern Detection flags the line-by-line pattern after submission | Already covered |
| Submits work matching another candidate's | Similarity Check, which raises the risk level automatically | Already covered |
| Has somebody else sit the assessment | ID Verification through a certified third-party provider | Already covered |
| Works from more than one location during a session | Network IP check | Already covered |
| Uses a phone off-camera | Video and snapshot proctoring, where recording is allowed for the role and region | Already covered |
| Runs a hidden AI assistant on the same machine | Nothing, because the tool hides itself from screen sharing | Detects the apps running on the candidate's device |
| Screenshots the task to share it or feed it to AI | Can't be prevented in a browser | Blocks screenshots during the assessment |
| Gets help from someone off-camera with recording turned off | Not detectable | Not detectable |
Every signal is evidence, and a reviewer weighs it before anything happens to the candidate.
Two things a reviewer can check for themselves
1. The risk level is deterministic
Fixed rules, no generative model, and the same inputs always produce the same result. Your reviewer can walk an auditor through every step of how a level was reached. A machine-learned score can’t be walked through that way.
2. The device check targets the evasion technique itself
Most platforms watch for known keyboard shortcuts, and the newer overlay tools have already adapted around that. The Codility App looks at how these tools hide from screen capture. Drop that behavior and the tool stops working.
Built to survive a legal review
- No AI or machine learning makes automated employment decisions. Scoring is deterministic and a human is accountable for every outcome.
- Codility does not train AI models on your candidate or employee data. That holds across every account, and no setting changes it.
- SOC 2 Type II audited. ISO 27001 certified. GDPR and CCPA compliant. WCAG 2.2 AA accessible.
- EU and US data hosting, with EU data. You choose your residency region at contract time.
- Designed to support compliance with NYC Local Law 144, and aligned with EU AI Act requirements.
- ID Verification runs through a certified third-party provider, and the raw identity document never gets to Codility.
- Integrity settings are configured per assessment and lock once the first candidate is invited, so every candidate works to the same standard.

What teams say once it’s running
“Codility has streamlined how we evaluate technical roles at Trimble. Beyond a great product and its proctoring features, their customer success team is responsive and dedicated, offering deep-dive support and guidance every step of the way.”
“With Codility, our teams ran 750 candidate tests over 90 days, saving 2,200 hours of interview time. That kind of productivity is like gaining time to launch an entirely new product or enter a new vertical.”
Questions buyers ask
Can a proctor detect AI?
Not reliably. Published research on AI-code detection tools finds critical precision and recall trade-offs and concludes that reliable detection does not currently exist. Codility gives your reviewer the evidence of how the code was produced: typing patterns, the code evolution timeline, paste and focus events, and a device check for hidden overlay tools.
