As the owner of a 13 Mini; what’s that?

We didn’t get anything at all from 18.1. There is literally nothing on my phone to tell me that it exists.

However, I do have it on both of my Macs, and have yet to do anything with it. I’m not in any hurry to bother either.

18.1 has some minor things, but the big ones are in 18.2. You will probably still not use them, but until you update, you probably won’t see them.

No, Apple Intelligence simply does not exist on any iPhone below a 15 Pro.
