MettleBox is a Chrome extension designed to enhance interview performance through AI-powered analysis. It allows users to record browser-based interviews, including those on platforms like Google Meet, Zoom, and Microsoft Teams. After each session, users receive a detailed performance report that includes predictions on outcomes, strengths, areas for improvement, and specific feedback on responses. The tool is tailored for job seekers, professionals, and career coaches who aim to refine their interviewing skills.

The extension operates discreetly, capturing audio from both the user and the interviewer without any noticeable disruption. Security is a priority, with all recordings encrypted and processed solely for feedback purposes. MettleBox is ideal for individuals looking to systematically improve their interview skills and is currently focused on product management and business interviews, with plans to expand into more domains in the future.
