AI Interview Assistant Browser Extension vs Desktop App: Which Is Safer?
TL;DR: Browser extensions for AI interview assistants tend to be more visible to an interviewer — reviewers have specifically noted a competitor's Chrome extension being visible during screen shares even while its desktop app runs in stealth mode. If minimizing on-screen visibility during a screen share is a priority, a desktop app is generally the lower-visibility option; a browser extension is often easier to install but shows up as an extra toolbar icon or permission prompt that a sharp-eyed interviewer could notice.
The claim
"Stealth" claims for AI interview tools vary meaningfully by delivery method — the same vendor can offer two different visibility profiles depending on whether you're using their browser extension or their desktop app.
The evidence
- A 2026 review of a well-known AI interview copilot explicitly noted that while its desktop app markets a stealth mode, "its browser extension is visible to interviewers" — creating what reviewers called a "two-tier stealth story" within the same product line.
- Browser extensions typically show a visible icon in the browser toolbar and can trigger visible permission prompts (microphone/camera access) that a shared screen would reveal.
- Desktop apps that run outside the browser window are generally not captured by a standard browser tab or window screen-share unless the presenter is sharing their entire screen rather than a single window or tab.
Comparison table
| Delivery method | Visibility during screen share | Typical setup |
|---|---|---|
| Browser extension | Visible toolbar icon; visible if entire screen is shared | Quick install, no separate app needed |
| Desktop app (window-share scenario) | Lower visibility if interviewer shares one tab/window, not full screen | Separate install required |
| Desktop app (full-screen share) | Same visibility risk as any other open app | Same as above |
Step-by-step: reducing visibility risk (if you choose to use live AI assist)
- Check whether your video call platform shares your entire screen or a single window/tab by default — this determines whether a background app is even visible.
- Close or minimize unrelated toolbar extensions before a call, regardless of which AI tool you use, to reduce visible icons.
- Test your specific setup in a mock call with a friend watching your shared screen to see exactly what's visible.
- Understand that no method guarantees invisibility — "stealth" claims describe typical configurations, not guarantees against every screen-share setting or every interviewer's setup.
FAQ
Are browser extensions always more visible than desktop apps? In most documented cases, yes — a visible toolbar icon and permission prompts are inherent to how browser extensions work, while desktop apps outside the browser window aren't captured unless the full screen is shared.
Does a stealth desktop app guarantee an interviewer won't see it? No — if the interviewer requests a full-screen share instead of a single window or tab, any open desktop app becomes visible regardless of stealth claims.
Which delivery method does InterviewBoost use? InterviewBoost supports desktop and mobile use; check current product documentation for the exact delivery method and any visibility-related settings.
Is using a stealth AI tool during an interview against the rules? Policies vary by employer and interview format — some explicitly prohibit any AI assistance, others don't address it. When in doubt, ask directly or default to using AI tools for practice and prep rather than live assistance.
