As showed in the "MY KARINA" video, i think it's a message/text application? Idk you tell me!

yes, it is very likely!

I thought maybe it was something related to their debut something like that ^-^

Probably! But i still reaaaally hope it's going to be available for everybody! Oh wait, din't SM just said the other day something about the AI's being available to chat with everybody or something like that? Idk, it's kinda of weird if you'd ask me.

SM app for us to interact with the A.Is

And that’s a fact!
