Also using this and have been for around a year now. I set it to pull thumbnails and descriptions off the videos and give it a specific folder in my main media drive so it’s easy to pick up in Plex. Worked great so far!

Worth noting too: you can set it up to monitor a playlist. I use this feature by making a public playlist and I add stuff to the playlist that I dont want to lose.

From purely a user perspective, because I haven’t dug into the tech behind either, I’d probably vote Matrix. Signal is nice but personally I find matrix easier to use for group chats and bigger rooms. I only have 4-5 people on signal and it’s useful for those moments but on Matrix I can find bigger chats to join and jump in and just talk with a handful of people.
