Undetectable AI Interview Tools: How Stealth Mode Works

How Undetectable AI Interview Tools Work

The key difference between detectable and undetectable AI interview tools is architecture. Browser-based tools leave fingerprints. Desktop-native tools with proper stealth engineering don't. Here's exactly how stealth mode works.

Desktop Overlay Technology

AissenceAI uses a native desktop overlay that renders above all windows but is excluded from screen capture APIs. On Windows, this uses SetWindowDisplayAffinity with WDA_EXCLUDEFROMCAPTURE. On macOS, it uses CGWindowLevel with sharing type exclusion. The overlay is physically visible on your monitor but doesn't exist in any digital capture.

Why Browser Extensions Are Detectable

  • Proctoring tools scan chrome.management.getAll() for active extensions
  • Content scripts inject DOM elements that can be detected
  • Network requests from extensions have identifiable patterns
  • Meeting platforms can query installed extensions via WebRTC

This is why AissenceAI is a desktop application, not a browser extension.

System Audio Capture vs Meeting Bots

Meeting bots join the call as participants — obviously visible. AissenceAI captures audio at the OS level (like recording what your speakers play), which is invisible to the meeting platform and other participants.
