ChatUnifier

ChatUnifier essentially bypasses normal ChatPlex servers, giving you the option to get YouTube chat without having to use the servers (Which are Patreon only!)

Overview

ChatUnifier allows you to add your own YouTube API key, bypassing normal ChatPlex servers. You use your own API key and secret from your Google Cloud Console, give the JSON secret to ChatUnifier through the web interface, and done!

Known issues

1. You have to click "Disconnect Youtube" and then reconnect in the WebUI in order to get it to load, if you don't start the stream before the game
   • Make this automatic, or a button in UI? (So we don't eat up our quota)
2. Sometimes messages duplicate after a while, will try to fix
