I hate that I can’t write em dashes freely anymore without people accusing the writing of being AI generated.

Even though they are perfect for usage in writing down thoughts and notes.

One thing you can try⸺admittedly it's not quite correct⸺is replacing them with a two-em dash. I've never seen an AI use one, and it looks pretty funky.

I have nothing against em dashes. As long as your writing is human, experienced readers will be able to tell it's human. Only less experienced ones will use all or nothing rules. Em dashes just increase the likelihood that the text was LLM generated. They aren't proof.

Why do you care what others accuse you of?
