Always on screen. Off the share.
A native desktop overlay for macOS and Windows that sits on top of your interview and stays off screen share. Captures coding problems from your screen, streams real-time answers, and runs as a quiet background process.
See it in action
The demo above walks through a real Amazon SDE interview scenario — behavioral questions, a HackerRank coding challenge, and two system design problems. All handled by the desktop app running invisibly in the background.
Live behavioral coaching
The app listens to the interviewer's audio, detects the question, and streams a structured STAR-format answer grounded in your resume — before the interviewer finishes asking.
Coding problems from screen
Hit one shortcut and the app captures the coding problem from HackerRank, LeetCode, or any platform. A complete solution with time and space complexity appears in the overlay within seconds.
System design walkthroughs
For architecture questions, the copilot generates a full design walkthrough — requirements, API design, data model, high-level architecture, deep dives, and scaling considerations.
Built different from browser tools
Browser extensions can be detected, blocked, and disabled. The desktop app operates at the OS level — outside the browser's reach entirely.
Stays off screen share
The overlay doesn't appear in Zoom, Google Meet, Microsoft Teams, Webex, or any screen sharing tool we've tested. It uses OS-level window exclusion, not a browser hack. Your interviewer sees your desktop, not the copilot.
Runs as a background process
The app runs as "CoreServices", a lightweight background process. It won't appear in your dock, taskbar, Activity Monitor, or Task Manager.
Screen capture solves coding problems
One keyboard shortcut captures any coding problem on screen — LeetCode, HackerRank, CoderPad, CodeSignal, or a shared doc. Hoppers reads the problem, generates a complete solution with time and space complexity, and displays it in the overlay within seconds.
Click-through overlay
The answer panel sits on top of everything but doesn't block your mouse. Click through it to interact with your browser, IDE, or video call underneath. Resize and reposition it anywhere on screen. It stays exactly where you put it.
System audio capture — no extensions needed
The desktop app captures your interviewer's voice directly from system audio. No browser extensions, no mic routing, no virtual audio drivers to install. It just works — on macOS and Windows.
Global keyboard shortcuts
Customisable shortcuts for everything — toggle visibility, capture screen, mute mic, navigate between answers, dock the window. All shortcuts work globally, even when the app isn't focused. Remap any of them to fit your workflow.
Dock mode
Snap the overlay to the left or right edge of your screen with one shortcut. It resizes to a slim panel that stays out of your way while keeping answers visible. Perfect for split-screen setups during coding interviews.
Auto-detects your interview
The app monitors for Zoom, Google Meet, Microsoft Teams, and Webex. When it detects you've joined a call, it activates automatically. No manual start needed — just open the app and forget about it until your interview begins.
Stealth by design, not by accident
The app is designed to stay off every screen sharing tool we've tested: Zoom, Google Meet, Microsoft Teams, Webex, QuickTime, OBS. It doesn't show up in screen recordings either.
It won't appear in your dock, taskbar, Alt+Tab, Activity Monitor, or Task Manager. The app ships as "CoreServices" — a process name designed to blend in with your operating system.
The app auto-detects when you're in an interview (Zoom, Meet, Teams, Webex) and activates automatically. No setup, no configuration — just open it and start your call.
