Congrats an the Asistant App launch!
Seems more snappy than web - other than that can't see a difference. Please add a read aloud function to the Assistant, which makes the app more useful. The assistant app will mostly be used on the go, and being able to listen to the output is a big plus.
A "read aloud" or "listen" button is almost a must-have for mobile AI chat apps and brings a lot of value, as one is not distracted by reading the output on a small screen.
