Introduction:

You know about the Interview Coder guy who made invisible AI window? 🫠🫠🫠 I don't like the fact that he taking advantage of poor job market and rip off poor students 😐😐. I rather make a fair game for everyone. I reverse engineering it and his whole thing was based on one functionality: setContentProtection from electron https://www.electronjs.org/docs/latest/api/browser-window This project is an improved version of the Open Interview Coder, an invisible desktop application that helps with technical interviews. It provides features like screenshot capture, AI-powered analysis, and solution generation without requiring login or authentication.

Open Interview Coder is an opensource invisible desktop application designed to help you succeed in technical coding interviews. It provides a discreet way to capture, analyze, and solve coding problems during interviews without being detected by most screen sharing and recording software.

The application works by creating an invisible window that can be toggled on and off with keyboard shortcuts. When visible, you can take screenshots of coding problems, get AI-powered analysis and solutions, and manage the application window.

Installation

Prerequisites

• Node.js (v18.19.0 or higher)
• OpenAI API Key

• Ensure the application has screen recording permissions
• On macOS: System Preferences > Security & Privacy > Privacy > Screen Recording
• On Windows: No special permissions needed
• On Linux: May require xhost access depending on your distribution

OpenAI API Errors

• Check your internet connection
• Ensure your OpenAI account has available credits

Window Not Invisible in Screen Sharing

• Some newer versions of screen sharing software may detect the window
• Try positioning the window in a less noticeable area of the screen
• Use the keyboard shortcuts to hide the window when not in use
