Stop turning everything into an antithesis

AI-generated marketing's reliance on contrasts like "It's not X, it's Y" constructions.

Hey there.

When it comes to AI usage in marketing, the cat is not just out of the bag, it’s halfway down the alley and starting a podcast (which I still think is a great idea for most companies, while we’re on the subject).

As a marketer who usually starts with the words behind it all, I use AI every day. For research. For outlines. For A/B testing ideas. For speeding up the parts of the job that don’t require a ton of taste or judgment. It’s a very helpful tool. It saves time and is getting better.

But it’s still very easy to spot the “AI did all the work” tells.

The most common culprit right now: antithesis built on negation. Some people call it contrastive reframing. Call it whatever you want.

How often do you read something like this?

  • It’s not a gym, it’s a movement.
  • It’s not a phone, it’s a paradigm shift.
  • It’s not a car, it’s a revolution.

This is the latest and easiest signal (the em dash was so 2025) that you’re letting ChatGPT, Gemini, Claude, or whichever tool you prefer do the heavy lifting.

What’s happening here

It’s a simple rhetorical combo:

  • Negation defines something by what it isn’t.
  • Antithesis sets up the dramatic contrast.

“It’s not X, it’s Y” checks both boxes. It sounds structured. It sounds authoritative. It feels persuasive.

And that’s exactly why AI uses it.

Large language models are probability machines. They predict the next most likely word based on patterns in their training data. Marketing copy — especially startup marketing copy — is filled with this kind of contrastive reframing. It’s a gym, but we say it’s a movement. It’s software, but we say it’s a platform. It’s a product, but we say it’s a category. The more we use that structure, the more it shows up in the data. The more it shows up in the data, the more AI gives it right back to us. It’s a loop, and not the good kind.

That structure shows up over and over again in decks, landing pages, press releases, and keynote slides. So when you ask AI to “make this more compelling,” it goes to the pattern that has historically signaled authority and persuasion. It’s pattern matching more than it is thinking.

And now we all sound the same.

What to do instead

If it’s a gym, call it a gym.

If it’s a phone, call it a phone.

If it’s a car, call it a car.

Then tell us why it’s better. Ideally evoke some emotion, and if you can’t, focus on the things people care about: Faster. Cheaper. Simpler. More durable. More useful.

When you say “It’s not a gym, it’s a movement,” what you’re often admitting is that you don’t have the conviction (or haven’t spent the time) to define the category clearly. So you try to float above it or blur the lines to appeal to investors.

Great positioning requires doing the opposite. Pick the box. Own the box. Improve the box. But don’t pretend the box doesn’t exist.

Negation is easy. Clarity is harder.

The bottom line

This isn’t about using AI or not using AI. It’s about not being used by AI.

If you want to stand out right now, here’s a simple tactic. Stop saying “It’s not an X. It’s a Y.”

Just tell us what it is.
