Google Wave is a unified communications tool that allows users to communicate with friends in real-time and foster collaboration, featuring outside functionalities like gadgets and robots, such as Twiliobot which turns phone numbers into click-to-call links. The platform is being released slowly to early adopters for testing purposes, and can be requested through an invitation. To learn more about Google Wave and its capabilities, users can visit the official documentation, developer resources, or join Twilio's developer community hub.
