Most interview tools are prep tools: mock questions before the call. Interview Copilot works during the real one. It listens to the interviewer through system audio - not your microphone - and answers technical questions in under a second. For live coding, screenshot the problem and get a working solution with the approach and time complexity, so you can explain the reasoning out loud. Native overlay: invisible on Zoom, Meet and Teams screen share. 16 languages. Free: 3 minutes + 2 screenshots
