Grok Bot for Linux: Unofficial port of the official app (open source) (github.com)

I doubt that Elon would authorize a Linux port. There's nothing the ragtag band of Linux supporters could offer monetarily to the world's first trillionaire.

Elon is supposed to be a Windows guy anyway, and class solidarity with the other billionaires ideologically encourages him to only do a Windows port.
