Relevance – The Most Easiest Way To Organize Your Tabs

Relevance is a private, nonintrusive browser helper. Its goal is to help you quickly find relevant results on the web, without intruding on your privacy.

Relevance can learn about your browsing habits based on the domains you visit. It’s not based on cookies, but it does use the IP address to identify you, and so it does have the potential to share data with its third-party service providers.
