🛡️ PhishGuard: A Full-Stack Phishing Detector

Yo, check out PhishGuard. It's this super cool app that's built to keep you safe from sketchy websites in real-time.
It's a Chrome extension, but it's got a Python-based FastAPI backend working behind the scenes.
It uses Google's Gemini API and Google Search Grounding to check out URLs and webpage content to find any hidden dangers.

🚀 What it Does

• Real-time Checks: Scans any webpage in a flash with just one click.
• AI-Powered Answers: An awesome AI gives you a straight-up "Phishing" or "Legitimate" verdict. No confusing stuff, lol.
• Smart Info: The AI's analysis gets a boost with real-time info from Google Search. It's way more accurate because of it.
• Super Secure: It keeps the frontend (the extension) separate from the backend (the FastAPI server) so your API key stays safe and sound.
