Let’s talk about the em dash. Not the little innocent hyphen, not its slightly more confident cousin, the en dash. No, I’m talking about the ‘EM dash,’ that long, dramatic line that AI looooooves to drop in your sentences like it’s getting paid per dash. Seriously, it’s the AI version of jazz hands.

You may not notice it, but most everyone else does. It’s the dead giveaway that you’ve let your favorite robot sidekick dress your words up in AI drag, and just like a bad wig reveal in the third act of RuPaul’s Drag Race, it can be… a little too much. Let me set the scene: You’re writing a heartfelt email to your team. Something vulnerable, maybe even raw: “I’ve been thinking a lot about the way we work together — and how we can be better — not just as colleagues, but as humans.”

Except, wait. You didn’t write that sentence, AI did. You just wanted it to fix a typo and maybe zhuzh up the tone, but now it’s full of em dashes, introspective pacing and oddly placed poetic pauses. You’ve officially been “EM-marked.”

What is the em-mark for AI?

The em dash is that long horizontal line (—) that’s often used in place of commas, colons, parentheses or the occasional dramatic pause. It’s like the Swiss Army knife of punctuation, and AI LOVES it.
