Instead of grinding practice problems, you launch the app before the call, keep it running in the background, and capture any question that appears in the shared editor or video chat. The app then produces a solution in the language of your choice, plus optimization notes and a short talk track you can read aloud. The design goal is discretion. There is no floating overlay and no window that shifts focus, so nothing appears in a screen share. It works alongside common interview platforms such as CoderPad, CodeSignal, HackerRank, and LeetCode, and it can answer in the same language you wrote your prompt in. Supported languages include Python, JavaScript, TypeScript, Java, Kotlin, Swift, Dart, C#, C++, Go, Rust, Ruby, PHP, SQL, R, HTML/CSS, Bash, Perl, Julia, Scala, and MATLAB. It is a paid desktop product with a free demo mode, an internet connection requirement, and macOS/Windows builds. Because it is explicitly built for use during a proctored or live evaluation, the ethical and contractual responsibility for using it rests entirely with the candidate and the rules of the hiring process. **Pricing & Plans:** Free demo mode to test the workflow, then subscription tiers: $79.99 per month or $199.99 for three months (roughly 15% savings). No credit card is required to start the free version. - **Screen-share safe operation:** Runs without overlays, dock icons, or focus-stealing windows so it does not show up visibly during a shared screen. - **Solution plus talk track:** Returns a complete working solution together with complexity analysis and explanation points you can say out loud. - **20+ language coverage:** Handles Python, Java, C++, Go, Rust, TypeScript, SQL, and many more, with responses in the language you prompt in. - **One-hotkey capture:** Screenshot any question from any editor or chat window and get an answer back in seconds during the round. - **System design and optimization help:** Goes beyond passing tests by suggesting better data structures, lower complexity, and follow-up improvements. **Strengths:** Purpose-built for live rounds rather than practice, so the workflow is optimized for speed; No overlay and no focus shifts, which reduces the risk of an obvious visual giveaway; Answers arrive with explanation points, not just code, which helps you keep talking; Supports a very wide set of programming languages in one desktop app **Limitations:** Requires an internet connection, so it cannot be used offline or on locked-down machines; No student pricing and no free tier beyond a limited demo mode; Using assistive tools during proctored interviews may violate employer or platform rules, so risk sits with the user [Profile (Markdown)](https://openaitools.app/tool/ghost-engineer.md) ## TechScreen 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. **Pricing & Plans:** TechScreen offers a free trial that does not charge a card, after which you pick a subscription plan. The company states every plan includes the full app, there are no hidden fees and no $1,000-plus tiers, and you can change or cancel at any time. Check the official pricing page for current amounts. - **Screen-share invisibility:** The app window is excluded from screen capture by the operating system, so it does not appear in Zoom, Teams, Meet, or session recordings. - **Typed and audio question capture:** Reads questions from typed text or live system audio, so answers appear as soon as the interviewer finishes asking. - **Keyboard-only control:** Show, hide, move, and send responses entirely through keyboard shortcuts, with no mouse movement that could give it away. - **Custom prompts and profiles:** Set your programming language, spoken language, role, and custom prompts so answers match the interview you are walking into. - **Multi-format interview support:** Covers software engineering, product, and other roles across programming and behavioral formats, with no visible app icon in the dock or tray. **Strengths:** Invisibility is implemented at the OS level, so it survives screen shares and recordings.; Reads live system audio, letting it react to spoken questions quickly.; Keyboard-only operation keeps the workflow discreet during a call.; Supports coding, system design, and behavioral rounds across languages and roles. **Limitations:** Only macOS 13+ and Windows 10+ are supported; no Linux build is listed.; On Zoom 6.16+ users must manually enable the window-filtering screen-capture setting for invisibility to hold.; Using an interview assistant raises genuine ethical and policy questions with employers and interview platforms.; Effectiveness still depends on the candidate explaining answers convincingly rather than just reading them.
