Google Wave is a new tool for communication and collaboration on the web, coming later this year. Google Wave introduces a new platform built around hosted conversations called wave. With the Google Wave APIs, developers can take advantage of this collaborative system by building on the Google Wave platform, and allowing people to communicate and work together in new and more effective ways. The service seems to combine Gmail and Google Docs into an interesting free-form workspace that could be used to write documents collaboratively, plan events, play games or discuss a recent news.
