Either KDE or GNOME. Nobody else has the ability to provide a similar level of desktop integration, especially in a post-x11 world.

I wouldn't expect a serious desktop Linux copilot offering until fully FOSS models are more commonplace and performant, anyways. You could easily make a half-assed tool that pipes it's output into the terminal (here's mine[0]) but it wouldn't be a very reliable or fast tool. There will be hundreds of "manage Linux with natural language" apps that just use OpenAI under the hood, but what you're really asking for is likely years away from being reality.
