The demo looks good.
I have some feedback and questions.
On the first read, I thought AI-Doctor is a doctor on AI field. So the title was a bit misleading. Not a problem, but if you want to share the video again perhaps you find a better title.
Then I was thinking at the character from the video. I wonder if it’s a good idea to use a human-like AI character which acts as a doctor.
I’m not sure if it’s okay or not. I just thought that as a patient I wouldn’t like to talk with a robot which looks like a human. This is somewhat strange.
What is this 
?
The conversation seemed sort of long (many tokens). How did you do it?
