How to make AI writing sound human

Nine edits that change how AI-assisted writing reads, in order of how much difference they make. No humanizer tools, no promises about detectors.

Updated September 25, 2026

How this was tested

The ordering of these nine edits is a claim, so it is falsifiable: on the checker’s built-in AI-style sample, the mechanical dash pass moves the pattern score from 96 to 68 and no further — vocabulary, rhythm and specificity are what the remaining 40 points are made of, and they are edits 1, 2 and 5 below. Reproduce it with npm run measure:tells in the site’s public repository.

The short version

  • The biggest wins are specifics and sentence-length variation. Everything else is polish.
  • Cut the opening that restates the question and the closing that restates the piece. Generated drafts almost always have both.
  • Do the mechanical punctuation pass first, so you are editing prose rather than dashes.
  • Read it aloud. If you would not say a sentence to a colleague, rewrite it.

Everything here is editing advice that happened to become urgent because of AI. None of it is a trick, and none of it will fool a detector, because detectors are not reading for these things. They are reading for how predictable your word choices are.

What these nine edits change is how the text lands with a person. That is the actual goal, and it is achievable in an afternoon.

1. Add specifics only you could know

Generated text stays unfalsifiable because being specific is risky. Every date, figure, name and place you add does two things at once: it makes the writing better, and it makes it unmistakably informed by something outside the model.

Generic

Wait times improved significantly after the change.

Specific

Wait times fell from 14 minutes to 6 between March and June.

Aim for one checkable detail every 150 words or so. If you cannot supply one, that paragraph may not need to exist.

2. Break the sentence rhythm

This is the strongest structural fix and the one people skip, because it requires reading rather than replacing. Generated prose clusters around 15 to 22 words per sentence with very little spread. Human prose swings.

  • Put a sentence of four words next to one of thirty. Let the short one land the point.
  • Follow a long, subordinate clause with a fragment. It is fine.
  • Allow one paragraph to run to a single line. Not every paragraph is a unit of thought.
  • Read the passage aloud and mark where you run out of breath. Those are the sentences to split.

3. Cut the frame at the start and the summary at the end

Two habits appear in nearly every generated draft. The first sentence restates your question, and the last paragraph restates the piece. Both are scaffolding, and both are visible.

Typical opening

When it comes to choosing a database for a small team, there are several important factors to consider.

Direct opening

We moved 40 GB off Postgres in a weekend. Here is what broke.

Delete the first sentence of a generated draft and read it again. It usually improves. Do the same with the final paragraph.

4. Clear the punctuation tells first

Do this before editing prose, so the dashes are not quietly influencing your reading. The AI dash remover removes em dashes, en dashes, typed -- and the look-alike characters in a single pass, and the count it reports tells you how much the model leaned on the dash habit.

Know what this step buys, measured: on our AI-style sample it cuts the pattern score from 96 to 68 and then stops, because punctuation is the only layer a machine can fix for you. The remaining 40 points live in vocabulary, rhythm and specifics — the edits above and below. Anyone selling a one-click humanizer is selling the first 28 points and staying quiet about the rest.

Do the punctuation pass first

Clear every dash character in one click, then edit the prose you can actually see.

5. Replace the vocabulary

Work from the maintained list rather than instinct. For each hit, ask what number, name or date could replace it. Where nothing can, the word is decoration and should go.

  • leverage → use
  • utilize → use
  • seamless → say what the user does not have to do
  • robust → the number it survives
  • comprehensive → what is actually covered
  • navigate the complexities → the specific hard part

6. Add one digression

Human writing wanders. It mentions the thing that went wrong, the tangent that turned out to matter, the objection you dismissed. Generated text never does, because a digression reads as a defect under local fluency scoring. One relevant aside per few hundred words changes how the whole piece feels.

7. Take a position

The both-sides hedge is a reliable tell: "while X offers benefits, Y also has drawbacks". Real writers, asked to compare two things, end up recommending one. Say what you think and accept the small risk of being wrong.

Balanced to the point of saying nothing

Both approaches have merits, and the right choice depends on your needs.

A position

Use Postgres. Only move if you are above 500 GB or need per-tenant isolation.

8. Use contractions and plain verbs

In anything that is not a formal report, it is reads stiffer than it's, and utilise is never better than use. This is not about dumbing down. It is about removing the register that models default to when they have no information about the audience.

The exception is academic and legal writing, where the formal register is required. In those contexts the fix is specificity and rhythm, not contractions.

9. Reorder for emphasis

Generated paragraphs tend to run claim, support, restatement. Human paragraphs put the surprising thing last, or first, or wherever it does the most work. Moving one sentence is often the difference between a paragraph that reads and one that files.

  1. Find the single most interesting sentence in the paragraph.
  2. Decide whether it is stronger as the first sentence or the last.
  3. Move it. Then read the paragraph again and delete whatever now looks redundant.

If you want a count of what remains after all nine edits, run the draft through the local checker. It is not a detector and will not tell you it sounds human, but it will tell you which habits you missed.

Frequently asked questions

How do I make AI writing sound human?

In order of impact: add specific facts only you could know, vary sentence length sharply, cut the opening restatement and the closing summary, replace the overused vocabulary, take a position instead of hedging, and add one relevant digression. Do the punctuation pass first so it is not distracting you.

Do AI humanizer tools work?

Not in the way they are sold. Paraphrasing output changes surface wording without adding information, which is why it tends to produce text that reads differently and knows exactly as little. The edits that make writing sound human are the ones that add something the model did not have.

Will these edits make my text pass an AI detector?

Probably not, and that is the wrong target. Detectors score token predictability rather than the tells on this page. If you are handling a detector result, the useful route is a drafting record rather than a style edit.

What is the single biggest tell to fix first?

Low sentence-length variance. It is the hardest habit to fake consciously, it survives a vocabulary rewrite, and it is immediately noticeable to a reader once you start varying it.

Is it dishonest to edit AI-assisted writing so it does not look AI-written?

Editing is not deception. What would be dishonest is submitting generated claims, citations or figures without checking them, or passing off which parts are your own thinking. Fix the substance; the style is a separate question.

How long should the editing take?

About ten minutes per 500 words once the habit is in place, and most of it is the specifics and the rhythm passes. The punctuation and vocabulary passes are mechanical and take under a minute with the tools linked above.
