PhishArmor

PhishArmor takes a different approach to email security. Rather than sitting at the network level or requiring IT department setup, it works as a lightweight browser extension that scans emails right where you read them. Click the extension on any suspicious email and it returns a clear scam score with a breakdown of exactly what triggered it — suspicious links, sender impersonation patterns, urgency tactics, and more.

Under the hood, PhishArmor uses Anthropic's Claude AI models to analyze email signals. The extension extracts only the relevant indicators — links, sender info, and text patterns — and sends them to the analysis engine. It never stores or transmits full email bodies, a privacy-first design that sets it apart from traditional email security tools that require full mailbox access.

The free tier gives you 10 manual scans per month, which is enough for spot-checking the emails that feel off. The Premium plan at $4.99/month unlocks unlimited scans, automatic scanning of incoming emails, and deeper analysis using Claude Sonnet for more nuanced threat detection. For individuals and small businesses without enterprise security infrastructure, PhishArmor fills a real gap — bringing AI-powered phishing protection to anyone with a browser.
