A.I. Texting Helper?

Would love to hear your thoughts on this idea

An app that serves an iOS keyboard with a built-in A.I. text writer

Say you want to text a boy/girl you like but don't know what to say, you know they love their dog though. So you type in "dog, ask out" somewhere and the bot would come up with something like "Date idea: your dog takes us for a walk"

Thoughts? Once the A.I. is working, the possibilities will be unlimited
