Signs of AI Writing: What Readers Actually Notice (and How to Sound Like You)

You've felt it before you could name it.

Three sentences into an email, a post, a landing page, and something goes flat. You're still reading the words, but you've stopped listening. There's nobody in there.

That feeling is the real AI detector. Not the software. You.

And it fires long before you consciously think "a machine wrote this." So if you write with AI (most people now do), the question worth answering isn't how do I beat a detection tool. It's what makes a human reader quietly check out?

Here's what they actually notice.

The signs of AI writing readers pick up on

Forget the tools for a second. These are the tells a real person feels, whether or not they can explain them.

Every sentence is the same length. AI writes in a smooth, even hum. Subject, verb, object. Subject, verb, object. No short punches. No long, winding ones that earn a hard stop at the end. Human writing has a heartbeat. Machine writing has a metronome. Read three paragraphs aloud and if your breath falls into a lazy, even rhythm, that's the tell.

It hedges on everything. "It's important to note." "There are several factors to consider." "This can often be a useful approach in many cases." That's a writer with no skin in the game, because there is no writer. A person who actually did the thing says the specific true thing and moves on.

It opens with throat-clearing. "In today's fast-paced digital landscape." "In an ever-evolving world of content." Nobody talks like this. These openers exist to fill the space before a point arrives. A human who has something to say leads with the thing.

It reaches for the same fancy words. Delve. Tapestry. Leverage. Landscape. Realm. Elevate. Seamless. Not wrong on their own, but stacked together they read like a model reaching for the statistically-safe word instead of the true one.

It loves the "it's not just X, it's Y" move. "This isn't just a tool, it's a philosophy." "It's not about the words, it's about the connection." One of those is a nice turn. Six in a row is a tic. Readers clock the pattern even when they can't name it.

Listicle-itis. Every idea broken into a tidy numbered list of exactly three, each with a bolded label and one supporting sentence. Clean. Scannable. Completely without a pulse.

Notice what's not on that list.

The em dash is not the tell

The internet has decided the em dash means a robot wrote it. As soon as some readers see one, they stop reading.

The writer Ann Handley had the best line on this. She described a CEO banning em dashes from company copy to avoid looking like AI, and called the whole panic what it is: reputational self-surveillance. Her analogy: Batman wears a cape, so by that logic anyone in a bath towel is Batman.

Punctuation is a terrible detector. Plenty of careful humans have used em dashes their whole lives. Plenty of AI slop uses none. Policing dashes just teaches good writers to pre-defend normal choices from imaginary accusations, and does nothing about the actual flatness.

(Full disclosure, our own house style skips the em dash. Not out of panic. We just like the rhythm of a hard stop. Your mileage can vary.)

So stop hunting the dash. Fix the real thing: the missing person.

How to put yourself back on the page

The fix for AI-sounding writing is not another tool that "humanizes" text. Running flat words through a second model gives you differently flat words. The fix is you.

Vary the rhythm on purpose. Follow a long sentence with a short one. A fragment. Like that. Read it aloud and let your own breath tell you where the metronome crept back in.

Trade hedges for specifics. Cut "this can often improve results" and name the result. The number, the moment, the thing that happened last Tuesday. A model invents plausible specifics; only you have the true ones.

Take a position. AI argues any side with equal, weightless conviction. Pick one. Say the thing you're a little worried is too strong. That worry is usually the sign it's yours.

Keep the aside only you would write. The joke, the tangent, the oddly specific reference. That's the fingerprint. It's the first thing a model sands off, so it's the first thing you should put back.

Read the whole thing out loud, last. The sentences you stumble over are the ones the machine flattened. Rewrite those in the words you'd actually say.

Where AI belongs (and where it doesn't)

We build an AI tool, so this is the honest part.

AI is genuinely good at the grunt work. The blank-page rough draft you'll mostly throw away. The outline. The tedious job of reshaping one thing you wrote into every format you need to publish it.

That last one is where Writeous lives. You write the piece in your own voice, one markdown file, then paste it in and get back a blog post, a newsletter, an X thread, and a LinkedIn post, each formatted right, in about a minute. It reshapes the words you already chose. It doesn't reach in and average out your point of view.

We'll name the limit too. When your blog runs on Ghost, Writeous re-syncs the published post in place, so editing your source updates what's already live. Social publishing through Typefully works, but a sent post can't be edited after it goes out, so that part is best-effort, not true sync.

The line to hold is simple. Hand AI the mechanics. Keep the thinking, the position, and the specifics for yourself.

The takeaway

The signs of AI writing aren't a font or a dash. They're the sound of nobody being home: even rhythm, endless hedging, borrowed openers, tidy lists with no pulse.

You fix it the same way you'd fix a boring conversation. Say the true, specific thing. Take a side. Sound like a person who cares.

Because the only writing that reads like a human is the writing a human actually showed up for.

Write once. Publish everywhere. Actually.
