Which also integrates with ytdlp. I run an instance of metube. If I want to watch a longer video I throw the video there, it downloads it, strips the sponsor stuff and makes it available on Plex.

I tried Sponsorblock for a while, mainly for getting all the garbage out of LTT vids. But I ended up turning it off because it always seems to jump a little to soon and a little too far. So it will jump from mid sentence to mid another sentence seemingly out of nowhere, which got to be too disorienting for me. Now I just use it for the little green marker and skip manually.

Also useful for skipping intros and recaps. Saves time for hn lurking.
