For those of us that aren't so technically inclined, here's the tool that I've been using to archive the YouTube videos.

Edit: For transparency, I know there's an self promotion asking you to upgrade on close, and if you think this is a valuable tool to help fight for Trump you should consider throwing them some money so they can keep developing this tool. Alternatively, if someone else has a known good freeware alternative, please respond to this post with that link. The main point of the OP is to make a tool that I'm using to archive YouTube videos more visible, not shill for the developers.

You should use whatever you feel most comfortable with.
