I am trying to stay open-minded here.
As it is, I don’t see a usage that justify install a privacy nightmare on the system level, an app, or even a browser extension.
The only time I have been using any AI stuff lately is when Brave_Search/Copilot_on_Bing do a quick summary of the search results, and give me the link to the website. It don’t need to constantly see what I am doing for that.
I’ve made a couple fun Discord bots for my friends, like a MtG card generator where you give a title and it creates a full card + art from that.
Other than that, lately I’ve been setting up some stuff on my home server, and it’s been great for working with various config files. (Of course, I wouldn’t trust this if I didn’t already generally know what I was doing to catch insecure recommendations.)
A few other things, but that’s the bulk of it.
