This is a project designed to allow for the running of a website which will deliver information about account changes while livestreaming; it uses Google's YouTube, Gmail, and Live Streaming APIs (and eventually others) to access information about your account, and provide a web UI for presenting this information.
This is an alternative to software like Stream Warrior/tnotify.
The intent is to allow an extensible way to add additional alerting into this application for additional features, e.g. highlighting on hotwords in livestream chat, connecting to twitter, connecting to other features of videos, etc.
This tool is designed to replace StreamWarrior for some of its uses, but may still be useful with a combination of other tools.
This is not an official Google product.
