Ah, thanks. Probably not something I'd use, but I can totally see how that would be a handy feature.
To my knowledge, there isn't anything like that on Android, sorry.
Swiftkey is a 3rd Party Keyboard for Android and iOS:

The autocorrect is great and it learns what you type so can make pretty good predictions about what your next words are going to be. If I start a conversation with my other half, my first question is commonly centred around our daughter so if type "Hey Sweetie", Swiftkey makes the assumption that my next few words will be "how's the little madam doing" so I wouldn't need to type it. All I do is press the space key to confirm its prediction. Does that make sense?
You can link it to your facebook/email accounts so it will learn from them too (although it's not something I've done).
They have a feature called Swiftkey Cloud which syncs your predictions & dictionary across devices and platforms so you get the same predictions on multiple devices.
It's not ideal/exactly what you're looking for, but it's the closest I can think of.
How big a deal breaker is this?
