As its name suggests, UnDistracted is an addition to Google Chrome that will become an assistant to control the time spent daily in sites that consume a lot of time.

Developers of this extension claim to have identified parts of each of these sites that call our attention and recommend unlimited content throughout the day. So by installing the extension we can hide these sections or even block access to these sites by blocking them.
The settings for this extension will be synced to your Google Account, so we can install on multiple computers and enjoy the same experience. You will find the add-on icon at the top of the browser so that you specify the location you want and activate what you do not want to see in any of these sites

For example, if we take a YouTube, we can prevent comments from appearing in any video we see, or prevent the sidebar that we recommend to other videos from being viewed, and even ban YouTube and others.
