No. It’s for IPTV channels that already exist. It lets you organize them and then make them available in Plex or Jellyfin.

If you’re looking to make your own channel from content you already downloaded, that’s what ErsatzTV and dizqueTV do.

If you’re looking to stream torrents without downloading them first, I’m pretty sure that can be done with Streamio and plugins, but I haven’t tried it.

I’ve tried Dispatcharr and was pleased.
