GoodChat is a Chrome Extension that automatically reduces spammy and repetitive messages in Youtube Chat, replacing it with a much more clear summary window instead!
In addition to its core function, GoodChat has a number of customization options, including the ability to use manual filters(including regex ones) in addition to automatic ones and a plethora of options to make the experience work for you.
This extension stores some message from the chat windows in which you participate, on your local computer only. This function may be disabled if you wish. This information is deleted afterwards. Your settings may be synced to Google Chrome's synchronization, if you allow this in your browser.
Your information is NOT collected, transmitted to or otherwise used by me or any other third-party.
