Everyone Can Smell AI Copy Now (Your Customers Included)

Can people tell your ads were written by AI?

Yes, and so can your customers. They will not call it out the way a Reddit thread does. They just scroll past while Meta keeps billing you for every impression. Vanilla AI produces the tells because it is a generalist winging it. The fix is not writing everything by hand, it is using AI that works like a real writer.

How can people spot AI writing so easily?

Over on r/PPC recently, a media buyer asked a genuinely good question: when does "let it learn" become "this campaign is dead"?

He never got an answer. The top reply was, roughly, "if you have a genuine question ask it in one paragraph without the story." The next one declared the whole site over if it could not deal with AI slop posts. Nobody touched the actual question. They were too busy pointing out that a robot had clearly written it.

Fair enough, honestly. The post had the lot. The tidy story arc. The "I have been thinking about this a lot lately" opener. Paragraphs so evenly sized they could have been cut with a ruler.

Here is the uncomfortable bit. Everyone can smell it now. You can. I can. A stranger on Reddit can do it in one paragraph, unpaid, at 8am, for fun. Your customers can too.

What does that cost you in your ad account?

Your customers are politer about it than Reddit. That is exactly the problem.

The people ignoring your ad in the feed do not leave a comment explaining why. They do not tell you the copy read like a machine. They just keep their thumb moving, and Meta keeps charging you for the impression anyway. You pay full price for attention you never earned, and the only signal you get back is a quietly disappointing set of numbers.

An ad that smells of AI is just a modern version of a boring ad. It does not stop the scroll, so it never gets the chance to sell.

Does the learning phase fix a bad ad?

This is where that media buyer's question actually gets answered.

"Let it learn" becomes "this campaign is dead" the moment you realise you are running a boring ad, because it was never alive to begin with. No learning phase fixes creative that people refuse to watch. The algorithm can only optimise towards attention that exists. If nobody is stopping, there is nothing to learn from, and no amount of patience or budget will conjure a result out of an ad that gets ignored.

So the instinct to wait it out, to give a flat campaign another few days to "settle", is usually just paying to discover something the creative already told you on day one.

So what actually fixes it?

The usual advice is to write everything by hand, like it is 2019. Lovely idea, except you have a business to run. The other option, spending your evenings hand-editing the robot out of every draft, is just writing it yourself with extra steps.

The problem was never AI. It is that vanilla AI is a generalist, and the tells are what winging it looks like on the page. A tool that has been taught to build an ad the way a real comedy writer builds one, step by step, does not produce those tells in the first place, because it is not guessing.

That is the whole difference. Not a cleverer prompt. A process. When the machine follows the same steps a skilled human would, what comes out reads like a human wrote it, and it stops the scroll instead of confirming everyone's worst suspicion about your brand.

Meet Brian

Brian is the world's only genuinely funny AI Marketer, and the reason he does not have the tells is that we spent months training them out of him. We broke down how our comedy writers actually build an ad, step by step, and taught Brian to work the same way.

We have seen that difference run to 2x and even 4x the click-through of the usual boring ads. Results vary, of course. We sell jokes, not miracles.

Take Brian for a spin and put ads in the feed that read like a person wrote them, because in every way that matters, one did.
