Home / Blog / 15 Words That Instantly Make Your Text Sound Like AI

Here is a party trick: paste almost any AI-generated article into a document, search for the word "delve," and watch it light up like a Christmas tree. AI models have favorite words — vocabulary they reach for far more often than any human would. A single one is harmless. A cluster of them is a flashing sign that says "a robot wrote this."

Below are the 15 worst offenders, each with a natural replacement you can use instead. Keep this list next to you while editing AI drafts, and your writing will instantly sound more human.

The 15 words (and what to say instead)

• 1. Delve — AI's all-time favorite verb. Real people almost never say "let's delve into this topic." Say instead: "explore," "look at," or "dig into."
• 2. Furthermore — Stiff and formal; humans in 2026 rarely use it outside legal documents. Say instead: "also," "and," or just start the sentence.
• 3. Moreover — "Furthermore's" twin. Same problem, same fix. Say instead: delete it, or use "plus."
• 4. Tapestry — "A rich tapestry of cultures." AI adores this metaphor; humans almost never use it sincerely. Say instead: "mix," "blend," or describe what you actually mean.
• 5. Landscape — "The digital landscape is evolving." Vague corporate filler. Say instead: "industry," "field," "world," or name the actual thing.
• 6. Realm — "In the realm of marketing…" Nobody talks like this at lunch. Say instead: "in marketing," "for marketers."
• 7. Leverage (as a verb) — "Leverage our platform to…" A business-jargon import AI overuses. Say instead: "use," or "take advantage of" when you need the nuance.
• 8. Robust — "A robust solution." AI's favorite adjective for anything sturdy. Say instead: "strong," "solid," "reliable" — or say why it is strong.
• 9. Seamless — "A seamless experience." Appears in nearly every AI-written product description. Say instead: "smooth," "effortless," or describe the actual experience.
• 10. Utilize — The poster child of needless formality. Say instead: "use." Always just "use."
• 11. Pivotal — "A pivotal moment." Dramatic, overused, and usually unearned. Say instead: "key," "crucial," or "turning point" — but only if it truly was one.
• 12. Comprehensive — "This comprehensive guide…" Fine once; AI uses it for everything. Say instead: "complete," "thorough," "full" — or let the content prove it.
• 13. "In today's fast-paced world" — The most clichéd AI opening ever written. It says nothing and wastes your first impression. Say instead: delete it entirely, or start with your actual point.
• 14. "It's important to note" — If it is important, just say it. This throat-clearing phrase adds nothing. Say instead: delete it, or "note that" if you must.
• 15. "In conclusion" — The classic AI essay ending. Real articles end with a final point, a question, or a call to action — not an announcement that they are ending. Say instead: just make your final point.

Why these words are a problem

It is not that these words are wrong — most are perfectly good English. The problem is density and predictability. Language models learned them from formal training data (academic papers, corporate writing, Wikipedia), so they reach for them by default. When five or six appear in one article, the pattern becomes visible: to readers, who feel the stiffness, and to AI detectors, which literally count how predictable each word choice is.

Think of it like an accent. One unusual word is a quirk. Fifteen is a dialect — and this particular dialect belongs to machines.

How to find and replace them in your drafts

1. Search, don't skim. Use Ctrl+F / Cmd+F on your draft and hunt each word from this list. Your eyes will miss them; search won't.
2. Delete first, replace second. Most of these words ("furthermore," "it's important to note," "in today's fast-paced world") can simply be removed. Try deletion before substitution.
3. Prefer the shorter word. "Use" beats "utilize." "Also" beats "furthermore." Shorter is almost always more human.
4. Add specifics instead of adjectives. Rather than calling something "robust" or "comprehensive," say what makes it so: "covers 40 topics," "handles 10,000 users."
5. Get a second pass. Paste your draft into a free tool like HumanWritr (no signup) to smooth out stiff AI phrasing, then do one final read-aloud to catch anything the tool missed.

One "delve" is a coincidence. Five is a confession. Search your draft before you publish.

FAQ

Should I never use these words at all?

You can — they are real words, and context matters. "Landscape" in a geography article is fine. The issue is the AI-style cluster: several of these words packed into formal, rhythmic prose. One in a natural-sounding piece harms nothing.

Will replacing these words fool AI detectors?

Partially. Vocabulary is one signal detectors use, alongside sentence rhythm and predictability. Swapping words helps, but pairing it with varied sentence lengths and real specifics is what truly moves the needle — because that is what makes writing genuinely human.

What if my natural writing style is formal?

Then keep your style — authenticity beats imitation. Formal human writing still has opinions, specifics, and varied rhythm. The goal is not to sound casual; it is to sound like you instead of a template.

Are there tools that do this automatically?

Yes. AI humanizers rewrite stiff, predictable phrasing into natural language. HumanWritr does this free with no signup — paste your text, click once, and review the result against this list as a final check.
