It is more the rule than the exception that any service using AIs are less usable than the previous solution. That is, unless you think about how usable they are to extract money from gullible investors or for making laughing stock of their users and/or developers.
In fact I while I'm certain they exist I cannot right now come up with a single product that I use for anything other than fun or creativity (games, painting) that have been improved by recent AI additions.
Thinking of it maybe maybe Google Translate qualifies, but that depends on how you define recent.
Oh, and by the way maybe there is something that qualifies as AI in some of the new translation web applications I've seen recently.
