What words make writing sound like ChatGPT?
The most recognizable AI words are delve, leverage, utilize, furthermore, moreover, seamless, robust, tapestry, plethora, myriad, pivotal, and game-changer. Combined with heavy em-dash use and openers like "In today's fast-paced world," they form a statistical fingerprint that both readers and AI detectors recognize instantly.
No single word convicts you. The density of them does.
Tier 1 — The dead giveaways
These words went from "normal English" to "AI fingerprint" in under three years. One of them raises an eyebrow; three in one article is a verdict.
| AI word | Write instead |
|---|---|
| Delve / delve into | dig into, look at, explore |
| Tapestry | mix, blend, combination |
| Plethora / myriad | plenty, lots, a bunch |
| Leverage (as a verb) | use |
| Utilize | use |
| Furthermore / Moreover | Plus, Also, And |
| Seamless / seamlessly | smooth, easily — or cut it |
| Robust | solid, strong |
| Game-changer | name the actual benefit |
| Elevate | improve, raise |
| Embark (on a journey) | start, begin |
| Unlock / unleash | get, access |
Tier 2 — The corporate padding
These are less famous but do the same damage: they add syllables without adding information, which is exactly how a model trained to sound "professional" behaves.
| AI word | Write instead |
|---|---|
| Pivotal / paramount | key, critical |
| Crucial | important, key |
| Facilitate | help, make easier |
| Foster | build, encourage |
| Holistic | complete, full |
| Synergy | teamwork — or delete |
| Cutting-edge / state-of-the-art | modern, new |
| Revolutionize / transformative | change, improve |
| Comprehensive | complete, full |
| Notably / Importantly | delete — just say the thing |
| In the realm of | in |
| Navigate the complexities of | handle, deal with |
Tier 3 — The phrases and structures
Single words are only half the fingerprint. AI also has favorite sentence skeletons, and these are harder to unsee once you know them:
⚠️ Density is the real tell
The fastest way to strip them all
You could hunt these manually with find-and-replace. Or paste your draft into the free ClickWise AI Text Humanizer — it swaps 100+ AI-tell words and patterns, fixes em-dashes and curly quotes, adds natural contractions, and shows a before/after AI-pattern score. It runs entirely in your browser, so nothing you paste ever leaves your device.
Then do the part no tool can: read it out loud, chop a few sentences short, and add one detail only you could know. That combination — mechanical cleanup plus human edits — is the full workflow we break down in how to humanize AI text.
