It's its s that's attached to it

Sometimes your keyboard also remembers when exactly you use certain words - like in the beginning of sentences, which most keyboards will capitalize by default.

I hate the whole "its" being converted to "it's" no matter what thing, but what I hate more is when I teach the keyboard a word, and it STILL won't let me use it. Taught my keyboard "that'd" and it would autocorrect it to "that's" every time. And unlike other words, if I went back and manually corrected it back, it wouldn't leave it, it'd force it back to "that's" again and refuse to let me change it. Come to think of it, it did that with "it'd" to "it's" too. Eventually I just switched to a different keyboard with much less aggressive autocorrect, since I still need the autocorrect to type with any semblance of speed due to minor coordination issues.

My old keyboard abruptly started autocorrecting more typos into what I was saying than it corrected toward the end anyway. Probably some shoddy attempt to implement AI auto correction.

I'm pretty sure I turned that off ~8-10 years ago and Google has just remembered it ever since

Also I use swipe typing so that probably helps too

Gboard does a pretty good job at highlighting your errors correctly in context. I'd guess it's iPhone users fucking up grammar that much.
