There are three main activities you can do within Pearltrees: organize, share and discover.
Easily organize what you've found on the web. The simple and intuitive interface makes sorting your interests, your passions and your ideas easy. Pearltrees allows you to give a precise meaning to the content you've archived making retrieval and reuse a pleasure.
You can also instantly share the content you've organized. In Pearltrees, everything is public. All other users can see what you've organized and you can see everything that others have collected. This lets you easily find users with common interests and when you do, you can team up with them and curate a topic together.
Pearltrees also lets you discover a web organized by others. Do you like discovering a city with a friend who already lives there? With Pearltrees, you can enjoy a similar though digital experience and learn about a new topic, a newsworthy issue or anything else that captures your attention, all curated by other people just like you.
