AI is always leaving fingerprints in online writing. The obvious tells change as models and prompts adapt, but the deeper texture is harder to disguise.

The three-line cold open

A common LinkedIn pattern begins with a broad observation, follows with a narrow reframe, and lands on a short declarative kicker. The conclusion arrives before the argument because the model is imitating the shape of authoritative writing rather than working its way toward an idea.

Perfect prose can feel lifeless

Another tell is writing where every transition lands, every paragraph resolves, and nothing feels accidental. It makes sense but leaves no residue. Real thinking often contains hesitation, a course correction, or a sentence that exists because the writer needed to discover the next one.

Human review is not optional

The goal is not to make AI output artificially messy. It is to have a person with judgment decide what is true, what matters, and whether the result sounds like something worth putting the organization’s name on. Readers notice when nobody who cared was involved.
