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 will start thinking outside the box going forward, but for my job this year, I was asked to write several company communications, which I never normally have to, and it wrote both for me almost perfectly. Took me about 5 minutes to edit them after and that was it. If I did this on my own, it easily could have been over an hour for each, I really hate that stuff.
