Coding Interview Copilot: Invisible, real time AI that helps you solve, debug, and explain code

Most coding interviews today take place entirely in your web browser (HackerRank, CoderPad, CodeSignal, Codility, etc.). Modern browsers are deliberately designed as secure sandboxes: code running in one tab is strictly isolated from everything else on your computer. This isolation is not a bug or an oversight — it's a fundamental security feature enforced by both the browser and the operating system.

Because of this sandboxing, interview platforms cannot reliably detect the following activities:
- Which app you switched to: When the browser tab loses focus (the "blur" event), the website receives no information about what other application became active.
- What other programs are running: Websites have zero access to the list of running processes on your computer. This is a core OS-level security boundary that browsers cannot bypass.
- Reading memory of other applications: Accessing another program's memory is strictly prohibited by the operating system for security reasons — not even native applications can do this to each other without elevated privileges.
- System-wide keystrokes or mouse clicks: The platform can only see input that occurs inside its own tab. It has no visibility into anything you type or click elsewhere on your computer.
- Hidden native windows during screen sharing: Applications specifically designed to remain invisible (e.g., Linkjob AI, overlay-style helpers) simply do not appear in screen shares, screenshots, or recordings when properly implemented.

In short: the browser tab is a sealed bubble. It can see only what happens inside itself — nothing more. Any claim that these platforms can "detect ChatGPT" or similar tools by watching your screen/activity outside the tab is technically inaccurate. They cannot.

Coding Interview Copilot is a discreet AI assistant that provides real-time debugging, logical reasoning, and problem-solving support during technical interviews, remaining invisible when the screen is shared.

Currently, the coding interview copilot only supports desktop applications. This is to maximize discretion and convenience for your use

LeetCode and HackerRank are coding practice platforms, whereas our Coding Interview Copilot is your real-time, invisible AI assistant during your formal interviews. It provides invisible support, reasoning, and debugging assistance, making it ideal for various technical interviews
