AI-powered proctoring with real-time monitoring, browser lockdown, and human review — 99.3% integrity rate across 12M+ sessions.
Three interconnected assessment dimensions that work together to build a complete picture of each candidate.
Real-time analysis of video, audio, and browser activity detects anomalies instantly without human reviewer bottlenecks.
Secure browser mode prevents tab switching, copy-paste, and external tool access — compatible with all major OS and device types.
Flagged sessions are reviewed by our specialist team with 4-hour SLA, providing a final human layer of confidence.
Online assessment integrity is non-negotiable — but heavy-handed proctoring creates friction that damages candidate experience and employer brand. Prelim's AI-powered proctoring system works silently in the background, flagging genuine anomalies without interrogating honest candidates.
Our multi-layered integrity system combines browser lockdown, AI webcam monitoring, keystroke analytics, and copy-paste detection — with a human review layer for flagged sessions.
Comprehensive assessment integrity that candidates barely notice and cheaters cannot bypass.
Computer vision detects off-screen glances, multiple faces, and device usage patterns — with confidence scoring for each flag.
Typing patterns, long pauses, and paste events are logged and analysed against expected patterns for the assessment type.
Secure browser mode prevents tab switching, screen recording, and external search while maintaining a smooth candidate experience.
Deployed across millions of assessments worldwide — proven, reliable, and fair.
AI-powered proctoring that's tough on cheating and gentle on candidates.
