Gmail AI Threat Scanner: An Open‑Source Security Layer for Your Inbox

Gmail AI Threat Scanner: An Open‑Source Security Layer for Your Inbox

Email remains the most common entry point for cyberattacks, yet most people rely entirely on whatever built‑in filtering their provider offers. I wanted something more transparent, more customizable, and more aligned with modern AI‑driven threat analysis.

What it Does

This project connects to your Gmail inbox, analyzes messages using AI-powered threat detection, and flags suspicious content - all while running locally so you stay in control.

• Scans Gmail messages using AI models for phishing, fraud, and social engineering indicators
• Highlights risky emails with clear explanations
• Works entirely client‑side using OAuth (no passwords, no server storage)
• Lets you review threats in a simple, readable interface

Why I Built It

I wanted a lightweight, open-source tool that gives users visibility into potential threats without requiring enterprise-grade infrastructure. Security shouldn’t be locked behind corporate paywalls - especially when AI can help individuals defend themselves.

Roadmap

• Add multi-model ensemble scoring
• Add attachment scanning
• Learning from False Positives
