10 Signs Your Text Sounds Like AI (and How to Fix Each) [2026]

AI writing has a texture. Once you learn to spot it, you see it everywhere — and so do readers and detection tools. Here are ten of the clearest tells, each with a fix you can apply in seconds.

1. Overused "AI words"

Certain words show up in machine writing at rates you rarely see from people: delve, tapestry, crucial, leverage, navigate, foster, robust, seamless, multifaceted, underscore. Fix: search your draft for them and replace each with a plainer, more direct word — or cut it.

2. Every sentence is the same length

Models tend to produce sentences of a similar, medium length, which creates a flat, even rhythm. Human writing is bursty. Fix: deliberately break the pattern. Cut one sentence to three or four words. Let another run long. Variation is the single biggest signal of natural writing.

3. No contractions

"Do not," "it is," "they are," "cannot" — all spelled out — makes text feel stiff and formal. Fix: contract them. "Don't," "it's," "they're," "can't." Instantly warmer.

4. Endless hedging

AI hedges everything to avoid being wrong: "it could be argued," "some may suggest," "there is evidence to indicate." Applied to obvious points, it reads as machine caution. Fix: state clear things plainly. Save hedging for claims that genuinely need it.

5. Transition-word overload

"Furthermore," "Moreover," "Additionally," "In conclusion" — starting sentence after sentence with a formal connector is a strong tell. Fix: delete most of them. Ideas usually connect fine on their own; if they don't, rewrite the sentence rather than bolting on a transition.

6. Generic examples

"A company saw improved results." "A student faced a challenge." These are placeholder examples — plausible but empty, because the model has no real experience to draw on. Fix: replace them with specifics — a real number, a name, a place, a concrete moment.

7. Suspiciously perfect structure

Topic sentence, three supporting sentences, tidy summary — every paragraph, exactly the same shape. Real writing is less mechanical. Fix: vary it. Start mid-thought. Drop a one-line paragraph. Let some paragraphs run short.

8. Uniform formality

AI holds the same formal register whether it is writing a legal memo or a birthday message. Fix: match the tone to the context. For casual writing, loosen up — use "you," ask questions, add a parenthetical aside, let a little personality through.

9. Repetitive vocabulary

Models often reuse the same handful of words rather than reaching for the variety a knowledgeable writer would. Fix: vary your word choice, and where a precise domain term fits, use it — it signals real expertise.

10. The "in conclusion" wrap-up

AI loves to end by announcing the ending: "In conclusion," "To summarize," "All in all." Fix: just make your final point. A strong last sentence closes a piece better than a label announcing that it is closing.

Fixing all ten at once

You can work through this list by hand — and doing it a few times will train your ear to catch machine rhythm on your own. When you want it done in seconds, a humanizer applies all ten fixes at once: it varies the rhythm, drops the AI phrasing, warms the tone, and restores a natural voice.

MakeItHuman does exactly this, with tone presets for essays, blogs, emails, and more, plus an honest estimate of how natural the result reads. As always, we call our score an estimate rather than a verdict — because no single tool should be the final word.

The bottom line

Text sounds like AI when it is too even, too formal, too hedged, and too fond of a handful of stock phrases. Fix those and your writing reads like a person's again. Learn the patterns by hand, or let MakeItHuman handle them for you.
