Is there personal AI assistant yet

So something I was messing around on with normal ChatGPT is making some personalities. After a bit I was thinking to myself it would be cool if it could go on the internet and do things for me, and go out of it's way to do things.

​

Like do we have something like Jarvis from Ironman, but we can make our own personalities and maybe even voices for the AI?
