I use Assistant to add reminders or stuff to my calendar (saying "Add appointment for 22nd of December at 2pm take sleigh out of garage" is a lot faster than clicking around the calendar UI), a few months ago Gemini couldn't do these things, yesterday it offers to do so after I connect it to the Workspace apps (I'm using civilian Google). But asking it to list my reminders gives me a textual listing in its UI instead of loading the Tasks UI...

Getting a response to "Set alarm for 8am" is still a lot quicker in Assistant than in Gemini.
