I'm using SwiftKey constantly for normal typing, and it's got a great autocorrect feature. Not using the AI (word suggestion/prediction) at all. Yet it drives me regularly insane, especially when typing technical terms, abbreviations and http addresses, because it just refuses to accept that there sometimes just has to be NO space after a dot. Also writing uppercase seems to be a hard task for SwiftKey. I'd like them to enhance the AI this way: if SwiftKey recognizes permanent violations of their built in rules, just ask the user if he wants SwiftKey to ignore certain rules. I assume something can be configured, but I didn't even bother searching for it (because lazy and afraid to get lost in the huge settings menu).
