Where to find new features

Hi all. New here!

I’ve been a pro subscriber for more than a year since I need it a lot for IT help.

Recently i read about all kinds of new features, like it responding with voice and so creating real-like conversations, and also about the memory feature.

I don’t see anything in the webapp like this however. I also can 't find a windows desktop app.

How can I use these features?

Regards,
S.
