Hackathon Project Note

This extension was created as a demonstration for the HackHazards 25 hackathon and is not available on the Chrome Web Store. As such, it must be loaded as an "unpacked extension" in developer mode.

The focus of this project was to showcase the integration of browser extensions with AI services (particularly Groq API) to enhance web security.

HackHazards '25 Submission
