Based on the LANChat application built for Windows devices, Chatter allows you to chat with anyone else, over multiple networks!
SATChat is a chat extension to allow users to talk with other people around the world. Inspired by Ham Radio, the extension connects to a open-source IRC server, allowing people to talk across town, around the world, and (technically) into space. The servers set language is English, but international keyboards are supported. Works for any device running the Chrome browser, including Windows, Mac, ChromeOS, Android, etc.
