## Description

PhishGuard provides a powerful, multi-layered defense against modern phishing attacks. It uses a fast, local engine to instantly scan emails for known malicious patterns, sender anomalies, and brand impersonation. For high-risk threats, it can consult the OpenAI API for an expert-level analysis. The add-on is designed to empower users by explaining why an email is flagged, helping them learn to spot threats. With user consent, it also helps build an open, anonymized dataset of phishing tactics to benefit the entire security community.
