Muninn for Chrome is now available! Install it from the Chrome Web Store

Muninn watches pages. Yggdrasil remembers them.

Muninn is a browser extension that checks pages against Yggdrasil and uses AI to catch threats that aren't in the database yet. If something looks wrong, it warns you before you type passwords or payment details.

In the browser
  • • Flags suspicious websites.
  • • Lets you trust sites you know are safe.
  • • Trigger deeper scans when something feels off.
In Yggdrasil
  • • Public record of reported URLs.
  • • Urls clearly labeled: phishing / clean / pending.
  • • Logged-in users can submit suspicious URLs for review.

Free during beta. Create an account to unlock all features.

Not found doesn't mean safe—just not yet reported.
