AI can draft a blog post in ten seconds. The problem is that most of what it produces reads like it was drafted by AI, and readers can feel it. The tells are specific and repeatable: a small set of words nobody says out loud, a few sentence shapes that show up again and again, and punctuation used the same way every time.

Here is the difference, in sentences you have definitely read before.

Sounds like a machine
  • "Our platform leverages cutting-edge technology to deliver seamless results."
  • "This is not just a tool, it is a game-changer."
  • "We are dedicated to excellence, ensuring a robust customer experience."
Sounds like a person
  • "It renders a 4K frame in two seconds."
  • "It does one thing: it flags the words that make you sound generic."
  • "Two of us built it. It has run for three years without a rewrite."

The left column could describe any company on earth, which is why it describes none of them. Paste your own text below and the checker highlights where you are doing it.

Why this matters beyond vanity

Generic copy costs you in two places. Readers trust it less, because it sounds like every other page they have skimmed. And AI answer engines like ChatGPT and Google’s AI Overviews are getting better at recognising low-effort, templated content, which is exactly the kind of writing that does not get quoted or recommended.

When you write with a clear point of view and specific facts, both audiences reward you: people stay on the page, and AI engines cite you as a real source. That is what writing for GEO, on top of classic SEO, is for.

The patterns the checker looks for

Words that expose you

A short list of words shows up far more in machine-generated text than in anything a person would say to a colleague: delve, seamless, robust, leverage, elevate, unlock, harness, showcase, tapestry, landscape, realm, testament, and a dozen more. None of them are banned in real writing. The tell is using them decoratively, where a plain word or a concrete fact would do more work.

Sentence formulas

  • Negative parallelism: "it’s not just a tool, it’s a movement." Say the actual thing plainly instead.
  • Significance tails: a sentence that ends with ", highlighting the importance of…" or ", ensuring a seamless experience." Cut the tail.
  • Rule-of-three padding: three adjectives or three examples stacked for rhythm rather than because there are three real things.
  • Filler transitions: "moreover", "furthermore", "it’s worth noting that." The next sentence usually connects fine on its own.

Punctuation habits

The biggest giveaway is the em dash used as the default pause, over and over. One in a page is fine. Four in a paragraph is a signature. The checker counts them so you can see when you have leaned on them too hard.

How we use this ourselves

Every word on this site runs through the same rules. When we build AI assistants or content systems for clients, we bake these checks in, so the output sounds like your business rather than a generic model. If you want AI working in your product without making everything read like a template, that is the kind of thing we build.
