What are some good quality AI integrations right now? The chat apps and the IDEs are sort of separate environments. A lot of "AI assistants" in other apps so far have been clunky/useless.

I don't even think Google has particularly good integration and they make Gemini. Although it was early when I was still using my Android phone, I went back to the old google assistant instead of letting Gemini take over because it didn't add anything of value for the basic functions that I need from a voice assistant. Hopefully that's changed and I'm simply uninformed, but I doubt it.
