What is an interview copilot?

An interview copilot is a real-time assistant that runs alongside a live interview. While you and the interviewer talk, it listens to the audio, converts speech into text, and uses a large language model to draft suggested answers, follow-up points, or code hints you can glance at while replying.

The goal is not to script you word for word. A copilot reduces blanking, jogs your memory on technical concepts, and helps you structure answers to behavioral or system-design questions, while you stay in control of what you actually say. Good copilots also read context you supply in advance, such as your resume and the job description, so suggestions refer to your real experience instead of generic filler.

SubcueAI is one example of this category. How it compares with other tools is on the best AI interview assistant page.

You are right to ask how a copilot hears the interview before you trust one, because the capture method decides what the other side can see and what can go wrong. This section answers that question: four approaches are in use, and each draws a different line.

• Meeting bot: a virtual participant joins the Zoom, Google Meet, or Microsoft Teams call and records audio on a server. Everyone on the call sees it in the participant list.
• Desktop dual audio capture: a native app on macOS or Windows reads the system output (the interviewer) and your microphone (you) directly from the operating system, without joining the call.
• Browser tab capture: an extension captures the audio of the tab running a browser call. It hears the interviewer but not your microphone.
• Second-device listening: a phone placed next to the computer hears the call through its own microphone while the call's speaker is on.

SubcueAI ships the last three and never the first. Its desktop app uses dual audio capture with a floating local overlay; its Chrome/Edge extension does live assist from a side panel for browser-tab calls (the Firefox build is mock-practice only); and its iPhone app's Listen mode hears an interview playing on another device, then drafts an answer when you tap. No bot joins the call and nothing is injected into the meeting page. Setup steps are in the tutorial.

Copilots tend to be most useful for:

• Behavioral questions where you want a quick STAR-style scaffold
• System-design rounds where reminders of trade-offs matter
• Technical phone screens with a lot of definitions and terminology
• Live coding when you need a hint on syntax or an algorithm

A backend engineer preparing for a technical phone screen is a typical case. She takes the call on her laptop, loads her resume into the copilot beforehand, and uses the suggested outline to answer a question about database indexing in her own words rather than reading it aloud.

Copilots are not a universal solution. An interview copilot cannot help, and may be visible, in these settings:

• Interviews where you share your entire screen
• Sessions that are recorded or run under proctoring software
• Company-managed devices where you cannot install third-party apps
• In-person or whiteboard interviews
• A call taken on the same iPhone the copilot runs on, which iOS never lets another app hear

We are upfront about these limits on the security page.

When comparing tools, the practical questions are usually:

• Does it join the call as a visible bot, or listen without joining?
• Which devices does it run on: macOS, Windows, a browser, a phone?
• Does it hear both you and the interviewer, or only one side?
• How are your audio and transcripts handled, and can you delete them?
• What does it cost per interview, and is there a free tier?

For SubcueAI specifics, see pricing and about. If you would rather rehearse first, the AI mock interview runs the same kind of questions without a live call.
