KingPhisher - Email Phishing Detector

Analyzes emails in your browser for phishing attempts. 100% local analysis - your data never leaves your device.

KingPhisher is a browser extension that helps you spot phishing emails. It works directly in Gmail, Outlook, Yahoo Mail, Yandex Mail, and Proton Mail. When you open an email in a chrome-derived browser, KingPhisher analyzes it and gives you a risk score from 0 to 100, along with a breakdown of what it found suspicious. Think of KingPhisher as a second pair of eyes, not a judge. It doesn't make decisions for you. It shows you what to look at so you can make better decisions yourself. Privacy. KingPhisher runs entirely on your computer. Your emails, sender addresses, subjects, and content never leave your browser. There is no server, no cloud storage, and no data collection. The only external communication is checking for extension updates through the Chrome Web Store.
