Tech Explained: How Whisper Stays Invisible

What interview platforms can see (inside the bubble)

window.addEventListener('blur', () => {
  // Handle when the user leaves the tab
});

codeInput.addEventListener('paste', (event) => {
  // React to paste events here
});

Some platforms may use webcam monitoring or screen sharing upon request.

What they cannot see (outside the bubble)

• Know what app you switched to when focus is lost.
• Scan running apps or list processes from a webpage.
• Read memory from other applications.
• Capture global clicks/keystrokes outside their tab.
• See invisible native overlays in standard screen shares.

function getRunningApps() {
  // No browser API exists for this!
  return navigator.runningProcesses || [];
}

if (getRunningApps().includes('SomeApp.exe')) {
  // Impossible check
}

Web sandbox cannot access local native apps

Why Whisper is different

• • It is a native desktop app living outside the browser sandbox.
• • Uses OS window properties to be excluded from screen captures and shares.
• • Global hotkeys toggle visibility without affecting browser focus or tab state.
• • Overlay controls help align content with the on-screen editor to avoid suspicious eye movement.
• • Provides reasoning and comments to articulate your thought process.
• • Relies on standard operating system features with no unusual footprint.

What about desktop proctoring apps?

While possible, reputable platforms avoid forcing invasive desktop software due to security, privacy, and trust concerns.

• Huge security risks (potential spyware)
• Major privacy concerns
• Breaks user trust

The bottom line

Because interviews run inside sandboxed browser tabs and Whisper runs as a separate native app, standard detection cannot see it.
