I often edit things in Word — I have a document that I can alt-tab to and type things. It has spellcheck, etc. that my browser window does not, and I’m not at risk of losing if I refresh or something. Then copy-paste back.

Word converts any - into an em dash based on context. Guess who’s always accused of being a bot?

The thing is, AI learned to use these things because it is good typographical style represented in its training set.
