I use it to manage a media server. And use natural language to download movies and series. Also I use to for homeassistant so I csn use natural language for vacuuming the house and things like that. I do use it for a number of other tasks but those are the most partical.
Good use cases, but I do want to point out that you can do all of that with HA itself. Are you using skills to talk to *arr services?
