GitHub kept recommending me the "interview-coder" repository for days. After finally checking it out, I discovered it was a paid service. While the concept was brilliant, I wanted a free and more customizable alternative. So I built Interview Corvus – an open-source, AI-powered assistant specifically designed for technical coding interviews.

What My Project Does

Interview Corvus is an AI-powered invisible assistant that helps with technical coding interviews. It:

• Captures and analyzes coding problems via screenshots
• Provides complete solutions with explanations using AI (OpenAI or Anthropic models)
• Analyzes time & space complexity of solutions
• Suggests optimizations and handles edge cases
• Works with multiple programming languages (Python, Java, JavaScript, C++, etc.)
• Supports customizable prompts and AI models in the interface

Built with Python and PyQt, it uses the OpenAI and Anthropic APIs for generating solutions. The application supports global hotkeys and works even when not in focus, making it perfect for interview scenarios.

Target Audience

This project is aimed at:

• Developers preparing for technical interviews
• CS students practicing algorithm problems
• Self-taught programmers learning data structures and algorithms
• Anyone who wants to understand complex coding problems better

While it's a tool that can assist during actual interviews, I built it primarily as a learning aid to help understand problem-solving approaches and algorithm complexity.

Comparison to Existing Alternatives

While the original "interview-coder" was my inspiration, Interview Corvus differs in several key ways:

• Completely free and open-source vs. paid subscription model
• Supports multiple AI models (both OpenAI and Anthropic) vs. single provider
• Fully customizable prompts that can be modified in the interface
• Screenshot-based problem analysis for quick problem capture
• Adjustable UI opacity for better integration with your workspace

The most significant difference is the flexibility - you can modify the prompts directly in the interface, connect to different AI models, and configure everything to your personal preferences.
