TechScreen

TechScreen is a desktop application designed to be an invisible co-pilot during technical job interviews. It runs on your computer during live coding sessions on platforms like Zoom, Google Meet, CoderPad, and HackerRank. Its core function is to listen to the interviewer's questions—via your system audio or microphone—and provide you with instant, accurate answers and hints directly on your screen, all without the interviewer seeing it. It aims to help candidates navigate tough questions and perform with more confidence.

What makes TechScreen stand out is its claimed invisibility. The tool states it does not appear in screen shares, recordings, or screenshots, which is its primary selling point for use in a monitored interview setting. It works as an overlay on your active window, so you don't need to switch applications. It supports multi-input analysis, processing audio and on-screen content, and can provide assistance for a variety of programming languages, from Python and Java to C++ and JavaScript.

This tool is built for job seekers who are deep in the technical interview grind, particularly those who may struggle with live problem-solving under pressure. The real-world use case is clear: you have a coding interview in an hour, you install TechScreen, and during the session, you get discreet, real-time support to help explain concepts, debug code, or understand a tricky algorithm question. It's a high-stakes tool for a very specific, stressful moment in a developer's career path.
