So instead of me having to go to find the magnet, and paste it in, this application monitors my shows, and when a new episode pops up, it picks up a release based on my criteria (quality, language, etc), sends it to qBittorrent, waits for the download, and puts it in a folder.
Radarr for movies, Bazarr for subs, Sonarr (mentioned above) for shows, and Prowlarr for search indexing.
Frankly the motivation that will finally make me build this is that my mom is complaining about the streaming service fragmentation... each of her favorite shows is on a different service with its own $20/month subscription, and that's on top of the $100/month for cable. For now she's just password sharing, but when that stops working I'll get around to setting this up for her so I can manage it remotely. Or maybe by then the services will figure out they'd be better off just streaming everything free on the internet and splicing ads into the streams. You know, like TV...
