Does an AI interview assistant need a browser extension?

Browser extensions can only see what happens inside a browser tab. That creates real constraints for interview use:

• They only work when the interview runs in a browser tab — not in the Zoom or Microsoft Teams desktop apps that most candidates and recruiters actually use.
• They depend on the browser's permission model and can be disabled by enterprise policies or managed profiles.
• They are visible in the browser's extension list and may appear in shared-screen views if the toolbar is shown.
• They typically cannot capture system audio cleanly on macOS without extra workarounds.

For these reasons, a browser plugin is rarely the right architecture for a general-purpose interview assistant.

SubcueAI is a native desktop application for macOS and Windows. That design choice matters because it lets the assistant:

• Capture dual audio — both the interviewer's voice (system output) and your microphone — regardless of which meeting platform you use.
• Work the same way in Zoom, Google Meet, and Microsoft Teams, whether you join via desktop client or browser.
• Render a floating local overlay on your own screen, separate from the browser and the meeting window.
• Avoid joining the call as a meeting bot, so there is no extra participant on the attendee list.

You can read more about the architecture on the SubcueAI home page or the tutorial.

Choosing a native app over a browser extension solves capture and compatibility, but it does not make any assistant universally invisible. Be realistic about these scenarios:

• If you are asked to share your screen and the overlay is on that screen, it will be visible.
• If your interview is recorded on the interviewer's side, your spoken answers are recorded as usual.
• Proctored exams and company-managed devices with monitoring software are out of scope — do not try to use an assistant in those environments.

More detail on these boundaries lives on the security page.

When comparing tools, ask the following:

• Is it a native app or a browser extension? Native apps generally cover more meeting platforms.
• Does it join the meeting as a bot, or run locally on your machine? Local overlays do not appear in the participant list.
• Does it capture system audio as well as the microphone? Without both, the assistant cannot follow the interviewer.
• Does it work with the desktop clients of Zoom, Google Meet, and Microsoft Teams, not just their web versions?
