I wonder what exact features this would provide that the mobile app cannot. I don’t wanna carry another device with me all the time
And that's why this (and any other stand alone "AI device") is doomed to fail.
We solved this problem already in 2007. "An iPod. A phone. An internet communicator. Are you getting it? These are not three separate devices."
The industry has been chasing that high ever since, failing to stop and consider that maybe the smartphone is effectively peak consumer tech as a delivery vehicle for various services.
OpenAI is just upset that they don't get to own the delivery vehicle, Google and Apple do.
