About

PhishGuard – AI Email Threat Analyzer

PhishGuard helps you identify phishing and suspicious emails directly in Gmail.

The extension analyzes the currently opened email and explains why something might be risky, helping users understand common phishing techniques.

What PhishGuard detects

• Sender domain mismatches
• Suspicious or shortened links
• Hosted content phishing pages
• Urgent or coercive language
• Social engineering patterns used in phishing scams

How it works

PhishGuard scans the currently opened Gmail message.

It extracts security signals such as sender domains and links.

Local detection rules analyze common phishing indicators.

AI provides a contextual explanation and risk score.

Instead of simply labeling emails as "phishing", PhishGuard explains the reasoning behind the analysis so users can learn how phishing attacks work.

Privacy-first design

PhishGuard is designed to minimize sensitive data exposure.

• Email content is processed locally when possible
• Personal information such as emails, phone numbers, and addresses are removed before analysis
• Only anonymized patterns and security signals are sent to the analysis server

PhishGuard does not store or sell user email data.
