Feature request : can the keydoard be smarter?

One feature that would be awesome, and I think it is very easy to implement :

Could the keyboard memorize the language for each conversation ? So we don’t have to switch all the time.
Sometimes I talk simultaneously to many persons with different languages and I always have to switch languages.

Also am I the only one that find the keyboard dumb ? At least in french. It sometimes corrects words that exists to words that don’t exist. And it doesn’t seem to know very basic grammatical or conjugation rules. I feel like I’m loosing more time typing with the automatic correction. I’ll try to post screenshot here to show you what I mean
