You know the sentence. “In today’s fast-paced digital landscape, it’s important to delve into the myriad ways businesses can leverage AI.” Nobody talks like that. Nobody thinks like that, actually. And yet AI text keeps producing it, paragraph after tidy paragraph, complete with the little summary at the end that nobody asked for.

This guide is about fixing that. Not tricking a detector, just making the writing read like an actual person sat down and typed it.

What you’ll be able to do

By the end of this you’ll be able to spot the tells that make AI text sound like AI text (em dashes everywhere, “delve”, suspiciously even sentence lengths, that closing paragraph that wraps everything up in a bow) and you’ll have a handful of methods to fix them. Some free, some quick, one or two that take a bit more effort. You’ll also know what these tools genuinely can’t do, which is just as useful.

Before you start

Here’s roughly what’s happening. Large language models are trained to predict likely next words, and across billions of examples, certain patterns come out looking “safe” and smooth. Even sentence lengths. Softening phrases. Neat transitions. A closing paragraph that restates the opening one. None of it is wrong exactly, it’s just… flat. Human writing wobbles. We write a nine-word sentence and then a thirty-word one that trails off a bit, and that’s normal, that’s just how people think out loud.

AI detectors exist because people wanted a way to catch this pattern automatically, schools especially. But they’re not reliable. False positives on genuinely human writing are well documented, meaning a student or a journalist can write something themselves and still get flagged. So the goal here isn’t “beat the detector”. It’s writing that a person would actually enjoy reading, which is a much better bar anyway. If you’re trying to sneak AI text past an assessed piece of work, this guide won’t help you with that, and honestly, that’s not what it’s for.

Get set up

Start with a proper check, not a guess. ScriptGrain, which is ours, has a free stylometric check at scriptgrain.com/ai-detect. It looks at measurable features rather than vibes: sentence-length variance, hedging language, punctuation habits, filler phrases, that sort of thing. Run your text through it and you get an actual sense of what’s making it read “AI-ish”, not just a score.

From there, ScriptGrain also has a humanise feature that revises the flagged text using those same measured features, and it goes a step further with voice profiles, so the output can sound like a specific person rather than just “generic human being writing a blog”. The free tier gives you one profile and one draft, which is enough to try it properly before deciding if you want more.

If you’d rather not use a dedicated tool, there are other routes. You can just tell ChatGPT or Claude directly what to stop doing, no em dashes, no “delve”, no tidy wrap-up paragraph, and that works fine within that session (it won’t remember for next time, so you’ll be repeating yourself a bit). Grammarly’s tone tools can help smooth things in a different direction, more about clarity and tone than “sounding human” specifically. And honestly, reading your draft aloud and editing by ear catches things no tool will, because your ear knows when a sentence doesn’t sound like something a person would say.

Try it yourself

Here are three prompts that each do something different. Copy them, tweak them, use them as a starting point.

This first one is a blunt instrument, good for a first pass on something an AI already wrote:

Rewrite the text below so it reads like a person wrote it, not an AI.
Rules: no em dashes, no "delve", "tapestry", "in today's fast-paced world",
or similar stock phrases. No neat summary paragraph at the end. Vary
sentence length noticeably, short and long mixed together. Use at least
one contraction. Include a mild opinion or aside if it fits naturally.

Text:
[paste your text here]

This second one is for when you’re generating something from scratch and want to head off the flat tone before it happens:

Write [describe the thing, e.g. "a 300-word explainer on how compound
interest works"] as if you're explaining it to a friend over coffee.
Use plain words. Keep some sentences short. Don't tie it up with a neat
concluding statement, just let it end when the point's made. Avoid
corporate-sounding phrases entirely.

And this third one is for spot-checking, useful once you’ve already got a draft and want the AI to interrogate its own output rather than rewrite it wholesale:

Read the text below and list every phrase or sentence that sounds
like typical AI writing (stock transitions, hedging, overly balanced
"not only X but also Y" constructions, a tidy closing summary). Don't
rewrite anything, just point out where it happens and why.

Text:
[paste your text here]

That third one’s useful because it teaches you to spot the patterns yourself, which matters more long-term than any single fix.

Check the result

Once you’ve had a go, test it properly rather than just eyeballing it.

Read it aloud. If you stumble over a sentence, or it sounds like something off a corporate slide, that’s your answer right there.

Count the sentence lengths in a paragraph. If they’re all landing between, say, fifteen and twenty-five words, that’s suspiciously even. Real writing bounces around, a short punchy line next to a longer rambling one.

Search for the obvious tells: “delve”, “tapestry”, “in today’s”, “it’s important to note”, “moreover”, “furthermore”. If any of these show up, that’s a giveaway, cut them.

Check the ending. Does the last paragraph just restate the first one in slightly different words? That’s the tidy-bow problem. Real writing tends to just stop, sometimes mid-thought, sometimes on a smaller point rather than a grand one.

Run it through ScriptGrain’s free check at scriptgrain.com/ai-detect and see what it flags specifically, then go back and fix those exact spots rather than rewriting the whole thing blind.

And ask yourself honestly: would I actually say this to a mate? If the answer’s no, it needs another pass.

If it doesn’t work

A few things to watch for.

First, privacy. Don’t paste anything sensitive into a public AI tool to get it “humanised”, that includes client work under NDA, medical information, anything with real names attached that shouldn’t be shared, financial details, unpublished research, that kind of thing. Most mainstream tools state in their own terms and privacy policies what they do with input data, and it varies, so check before you paste rather than after.

Second, don’t use any of this to fake authorship on something that’s meant to be assessed as your own work, a university essay, a professional certification, whatever it is. Humanising AI text doesn’t make it your writing. It just makes it read better. Those are different things, and worth being honest with yourself about which one you’re doing.

Third, and this one catches people out: sometimes no amount of humanising fixes flat source material. If the underlying content is thin, if there’s no actual insight or specific detail in there, all the sentence-length variation in the world won’t save it. You can smooth the surface all you like, but if there’s nothing underneath, readers notice. In that case the fix isn’t a better prompt, it’s going back and adding a real example, a specific number, an actual opinion, something only you would know or think.

Keep exploring

If you want the output to sound specifically like you rather than just “a human, generically”, have a look at “How to get AI to sound like me”. If it’s the editing side you need rather than generation from scratch, “How to get AI to edit my writing” covers that. And if you’re doing this for a business or a brand rather than yourself personally, “How to get AI to sound like my brand” is the one to read next.
