YouTube Comments History automatically saves links to all the public comments you’ve left across Youtube. Your public comments are visible to everyone but the Comments History can only be accessed by you.
Comments History also contains the link to the video where you’ve left the comment along with the date and time when the comment was made. Clicking on this link would open the video page with your comment highlighted at the top of the Comments section.
Comments History makes it a lot easier to locate, edit and delete your old YouTube comments and replies. YouTube also allows you to Export or Download this data in the .zip file format for offline viewing.
