Does your post sound like AI? The tells to fix before you hit post

People scroll past posts that sound like AI. Here are the giveaways our team spots in seconds, and how to fix them before you post.

The Big Idea

On episode 7 of The Visual Marketing Podcast, I put our photographer Billie to the test. Our copywriter Emily had prepared four short social posts about phone photography. Some were written by her, some by AI, and they got harder to pick as they went.

Billie can usually tell in about ten seconds. She picked three out of four.

The reason this matters is what Billie told me next. When she can tell a post was written by AI, she often scrolls past within two sentences. Not because it’s bad, but because it always sounds the same. All the effort that went into the idea behind it is lost.

And she’s not alone. Your customers are getting better at spotting it too.

If it doesn’t sound like something you’d say to a customer across the counter, change it until it does.

Run your next AI-written caption past this list before you post it. These are the tells Billie pointed out on the episode.

  • Emojis at both ends of the title. A camera at the start, sparkles at the end. People rarely write that way.
  • Writing in threes. "Natural light, thoughtful composition and consistent framing." AI loves a list of three. Cut one, or rewrite the sentence.
  • "It isn’t this. It’s this." AI often tells you what something isn’t before telling you what it is, even when nobody said it was. Just say the thing.
  • Stacks of short sentences. "Read that again." "You don’t." Short punchy lines one after the other are a classic giveaway.
  • The big finish. A short line at the end that doubles down, or a question tacked on to get comments. End where a real person would.
  • Buzzwords and borrowed accents. Leverage, elevate, unlock, fundamentals, simply. Swap them for the words you’d use out loud. Billie spotted the human-written post partly because it said "easy", a word Kiwis love.

One more you’ll hear about: dashes. They’ve become a famous tell, but plenty of people use them, so on their own they’re not proof. We leave them out anyway.

How to use AI and still sound like you

We use AI in almost every part of our process at C i Marketing. It makes our work faster and more efficient, and we help our clients use it better too. But we use it the way a hairdresser uses a pair of scissors. It’s a tool. A person is still directing it and checking everything it makes.

That’s the bit most people skip. Start with your own idea and your own story, let AI help you shape it, then read it back out loud. If it doesn’t sound like something you’d say to a customer across the counter, change it until it does.

Here’s something that surprised me. When Emily wrote the AI versions for our test, she had to tell ChatGPT to be more like AI and less like her, because it had learned her style so well. Paid business tools that learn from you can sound a lot more human. The free version with a one-line prompt usually doesn’t.

What’s Moving: AI comments on LinkedIn

A Pangram Labs analysis of 57,000 public LinkedIn posts, reported by Social Media Today in August, estimated about 30% of comments from April to June 2026 were entirely written by AI. The detection method hasn’t been published, so treat the number with some caution. At the same time, LinkedIn now orders comments by how relevant they are to each viewer, so a generic "Great insights, thanks for sharing" is unlikely to do you much good.

Is it wrong to use AI to write my social media posts?

Not at all. We love AI for making jobs quicker, and it can save a busy business owner heaps of time. Where people come unstuck is letting it do all the thinking, then posting whatever comes out.

You have to use it properly, and the result has to sound authentically human. That means your story, your words and your checking, every time.
