How to rewrite AI text into living prose: an editor's checklist

A machine draft almost always reads the same way: smooth, even, and about nothing. That's not a disaster, it's raw material. The problem isn't that it's full of mistakes; it's the opposite. There are almost no mistakes, and that's exactly why the text feels as sterile as a vacuum-cleaner manual. I rewrite paragraphs like this every day, and over a few years I've built a short checklist. Here it is, along with how to rewrite AI text so a human shows up in it again.

How to spot that a paragraph was written by a machine

Before you fix anything, learn to see the tells. Almost every draft has a few of these:

  • Empty adjectives. Words like "stunning" or "striking" that show nothing: they slap a rating on the scene instead of giving you the picture.
  • Even rhythm. All sentences roughly the same length, so the text rocks like a metronome.
  • A named emotion instead of a shown one. "She was sad," instead of dropped shoulders and an unfinished cup of tea.
  • Over-polite dialogue. Everyone phrases their thought in full sentences and nobody interrupts.
  • A summary sentence. At the end of a paragraph, AI loves to explain what happened and what it meant.

If you spot three out of five, you're looking at a typical machine blank. That's fine. Now you have to bring it to life.

The steps: how to rewrite AI text

I work in this order, from coarse to fine.

  1. Read it aloud. Wherever you stumble or get bored, that's what to fix. The ear catches machine-ness faster than the eye.
  2. Cut every second "very / so very / extremely." Intensifiers dilute. Leave one per paragraph, replace the rest with an action.
  3. Break up even sentences. Set a short, clipped line next to a long one. Rhythm comes alive on contrast.
  4. Swap a named emotion for a shown one. Not "he was angry," but what he did with his hand, his voice, his eyes.
  5. Give the character their vocabulary back. A teenager doesn't say "exceedingly distressing." Snape doesn't say "buddy." Give each their own words, their own sentence length, their own favorite pauses.
  6. Delete the summary sentence. If the scene is clear, the explanation at the end is dead weight. Let the reader put it together; they're smarter than the machine assumes.

Don't try to do it all in one pass. I usually go twice: the first time, a rough clean-up (intensifiers, rhythm); the second, voice and detail. That way you miss fewer tells, because the eye gets used to the text fast.

A full before/after on one paragraph

Here's the raw output from a generator:

Hermione was very upset. She felt that Ron didn't understand her, and this caused in her a strong feeling of loneliness. She thought that maybe they should talk about their feelings openly. It was a difficult and very emotional moment for them both.

Four even sentences, the emotion named three times, a closing summary. A metronome. Now after a human hand:

Hermione read the paragraph a third time and still didn't understand a word of it. Ron was saying something about Quidditch. "Mm-hm," she said. The book lay open, but she was looking through it. She should tell him. Only, how to start? "Listen, I don't think you really…" No, it'd come out like an accusation.

The same loneliness, but through the paragraph read three times, the tossed-off "mm-hm," and the broken-off line. Not a single "very." The emotion isn't named. It's visible. And notice the rhythm: a long sentence, then three short ones, then a long one again. That swing is exactly what a reader feels as living speech.

The hardest tell is evenness

Empty adjectives and named emotions show up at once, so they're easy. The most insidious tell is the one that doesn't catch your eye: evenness. The machine writes as if every sentence came off the same lathe. No sharp stops, no unexpected short line, no spot where the author suddenly let themselves exhale. The text is technically correct, and that's exactly why it's dead.

You fix this with rhythm, not vocabulary. A few moves I use every time:

  • Put a period where the model put a comma. One long sentence is often better split into two: the short one hits harder.
  • Allow yourself an incomplete sentence. "Silence. The same silence again." That's normal living prose, not an error.
  • Read the paragraph and ask: where would I pause if I were reading aloud? That's where the break in rhythm belongs.

The moment a paragraph gets even one such swing, it stops sounding like a machine, even if the rest of the words barely changed. It's the cheapest edit of all in terms of effort: you're not inventing new images, only moving periods and commas around, and the effect is as if you'd rewritten the paragraph from scratch.

An honest caveat

AI gives you even but bland text, and that's the whole point of editing. The machine will never slip in the way you need it to: it won't cut a sentence off where a character runs out of breath, won't drop in the out-of-place joke that's exactly what makes a scene alive. Evenness isn't quality. Taste, rhythm, and the right kind of break β€” those are yours, and you can't hand them to a generator.

FAQ

How much do I need to rewrite?

It depends on how close the draft is to your voice. Usually the first pass is 30–50% of the text: intensifiers, rhythm, named emotions. If a paragraph no longer trips you up after a read-aloud, leave it. Don't rewrite for the sake of rewriting; the goal isn't "not a single machine word," it's that the text sounds like yours.

How do I keep a character's voice?

First, spell out for yourself how they talk: which words they like, what they'd never say, where they're being ironic. Then go through the dialogue and throw out everything that sounds the same in everyone's mouth. A useful trick is to start from a precise prompt where you described the character's manner directly: then the draft is closer to what you want, and there's less to fix.

If a blank screen scares you more than editing does, generate a draft and start from there. Try a Harry Potter chapter, or see how others hold drama together. AI takes away the fear of the first line, and the voice stays yours.
