I've been "dogfooding" this for the past week, and I think it's actually kind of neat. It's way better than generically chatting with an LLM.
This repo includes a detailed setup wizard. You give it some info about yourself, which can include personal blogs/websites to scrape, github, mastodon, text documents, or just paragraphs you write off the top of your head. It builds a profile of you, and then builds _them_ off of that.
You invite your new friends to your group chat by selecting and possibly editing them in a TUI. Then you can just deploy to local Docker and forget about it. Too crepy? Drop the docker container and remove ~/.sudomake-friends.
I know this reeks of dystopian future, I get it. I think of it as a fun little toy, and I also kind of just want to see what the community feedback is.
