AI writing has a vocabulary. Once you notice it, you can't unsee it — the same handful of words and phrases turn up again and again. Avoiding them is one of the fastest ways to make text sound like a person wrote it. Here's the hit list, and what to use instead.
Overused AI words
These aren't bad words by themselves — they're just wildly overrepresented in AI text, so they read as machine-made:
- Delve → "look at," "dig into," "explore"
- Tapestry (as in "rich tapestry of") → just describe the thing
- Utilize → "use"
- Leverage → "use," "rely on"
- Facilitate → "help," "make easier"
- Robust → "strong," "solid"
- Realm → "area," "field"
- Showcase → "show," "highlight"
- Foster → "build," "encourage"
- Seamless / seamlessly → "smooth," or just cut it
- Multifaceted → "complex," or be specific
Stock AI phrases (the real giveaways)
Phrases are more telling than single words. These scream "AI wrote this":
- "In today's fast-paced world…"
- "In the ever-evolving landscape of…"
- "It's important to note that…"
- "When it comes to…"
- "Navigating the complexities of…"
- "Plays a crucial/pivotal role in…"
- "A testament to…"
- "Whether you're a beginner or an expert…"
- "In conclusion, …"
- "Unlock the potential of…"
Most of these add nothing. Delete them and the sentence usually gets stronger.
Filler transitions to cut
AI loves announcing every turn. Cut most of these and let ideas connect naturally:
- Furthermore, Moreover, Additionally
- However (when overused), Nevertheless
- Therefore, Thus, Hence
- Firstly, Secondly, Lastly
You don't need to ban them — just notice when every paragraph starts with one. That pattern is the tell.
The deeper fixes (beyond word-swapping)
Swapping words helps, but the biggest tells are structural:
- Uniform sentence length — vary it. Long, then short. (More in how to make AI text sound human.)
- No specifics — add a real example, number or detail.
- Everything hedged and neutral — take a clear position; have a voice.
The fast way to clean it up
Editing all of this by hand is doable but slow. Grade A Humanizer rewrites text to strip the stock phrases, swap over-formal words for plain ones, and vary the rhythm — handling the mechanical cleanup in one pass. Then you add your specifics and check it sounds like you. Tool for the grunt work, you for the voice.
The bottom line
AI text gives itself away with a predictable vocabulary. Cut the stock phrases, prefer plain words, drop the filler, and vary your sentences — and your writing stops sounding like a machine and starts sounding like you.
