You mean autocorrect and voice to text stuff and not AI, right? Because this is one area I find the AI to actually be good at while the non-AI versions are just garbage.
Predictive typing/autocorrect has a nasty habit of changing correct words to entirely different words that do not in any way fit with the context. And I know they look at context, since it will sometimes change a word I wrote 4 words ago when I no longer even notice because I'm looking where I am writing and not 4 words ago.
