I found myself on the receiving end of this product recently, and I felt like I was in a weird pseudo-uncanny valley. What would this AI understand? Would a person read it if it was unparseable by the current system? What if I wanted a little nuance in the conversation, something like, "What's best for me is 1pm on Monday, but if that's a hassle for the other party, I can make Thursday afternoon work"?

Human assistants can handle that just fine (and in fact, is a hugely valuable skill in good admin assistants), but I felt uncomfortable interacting with a system where I didn't know what was possible.

Since this is their whole business, I'd hope that you could talk to the service as though it is a person and have it be understood, whether by the AI or a human trainer (these are mentioned in their FAQ I think).

For all we know - there is someone who is sitting there - being a killer assistant to the beta users! Do things that don't scale :D

Well that's the new age @mattzito test the possibilities! We have still to receive this - we are patiently waiting
