Psi

About Psi

is an instant messaging application for Windows, Linux, and Mac OS X that connects to the free, open Jabber IM network (also known as XMPP).

Google Talk, LiveJournal, and Portugal Telecom are just a few of the groups that are actively using the Jabber network around the world — and many other companies and educational institutions are still joining in. Psi allows you to seamlessly chat with anyone connected to this global IM network through services like these.

Whether you use Windows, Linux, or a Mac, Psi is right at home on your desktop. From the system tray icon on Windows to the dock badges on Mac OS X, Psi takes advantage of each operating system’s unique features and appearance to provide a first-class IM experience on almost any computer.

And since Psi is designed to be fast and lightweight from the ground up, you’re free to enjoy all of its features without slowing down the rest of your system.
