Still a bit clunky but I self-host tubesync and it works pretty well:

I tried https://github.com/alexmerkel/archivetube but it was not a great experience.

I felt that keeping it in Jellyfin and grabbing metadata using https://github.com/ankenyr/jellyfin-youtube-metadata-plugin was nicer. Plus way more client support than just a web browser.

While we're on the topic, have a look at TubeArchivist

It'll get less clunky in the future when I get some time to fix a few bits and bobs, honest!
