One use case example:
We ask all customers how their experience was with us. If they respond and it's positive, we send them a link to ask for a review. If it's negative and/or they also have other points raised, we handle those.
If rules had an option to work like below it would be amazing:
OpenAI Query: If contents of email is positive and does not require any further action from us THEN reply with Email Template. If contents of email is negative, reply with Email Template 2 and Label it "To Action".
I'm sure there are many other ways AI in rules could be used, for example to triage support tickets by priority or by best User to respond etc.
