TechScreen is a desktop application built around a single promise: giving candidates real-time answers during interviews without the interviewer knowing. It works for coding rounds, system design, and behavioral interviews, accepting questions either typed in or captured from your system audio, which means it can pick up what an interviewer is saying on a call and surface an answer almost immediately.
The core technical claim is that invisibility comes from the operating system rather than a visual workaround. The app window is excluded from screen capture at the platform level, so when you share your screen on Zoom, Microsoft Teams, Google Meet, Webex, Amazon Chime, CoderPad, Codility, HackerRank, or similar tools, your audience sees the interview question but not the assistant's answer. The site notes that Zoom 6.16+ requires enabling window-filtering in the screen-share settings, and states that platform compatibility is re-checked daily.
The interface is designed around keyboard shortcuts so nothing on screen hints that help is being requested. Screenshots, conversation mode, sending answers, hiding the window, and repositioning it are all bound to hotkeys, and the window floats above your IDE, browser, and call. Users can configure programming language, spoken language, role, and custom prompts, and the vendor advertises that no user has been detected to date.
