44 Agents Tried to Break My Case Studies. Three Succeeded.
I reviewed my own five case studies and passed clean. Then 44 AI agents were told to refute the copy. They found 38 problems. Three would have embarrassed me.

Most copy that ships in 2026 has AI in it. That is not the problem. The problem is that AI introduces specific, recognizable patterns that your readers can clock in three seconds, and most writers can’t see those patterns in their own work because they wrote it. Here’s the checklist I run on every page before publishing. The same patterns also let a founder review an inbound deck or LinkedIn post and tell whether the operator pitching them is doing the work or just narrating from a model.
If you’ve ever read a piece of copy, gotten a vague “this feels off” reaction, and not been able to say why, it was probably one of the patterns below.
Most of these tells aren’t “wrong.” They’re just statistically over-represented in AI output. A real human writer might use one of them now and then. AI writers stack five of them in the same paragraph.
Em dashes aren’t banned in English. Real writers use them. AI uses them constantly, often in places where a period or comma would land harder. If your piece has an em dash in every other sentence, you wrote it with AI in the loop.
Example to fix:
“X, Y, and Z.” When three is the right number of things, list three things. When three is just rhythm, you’re imitating Steve Jobs’s keynote cadence and the reader feels it.
Example to fix:
The reversal feels balanced and wise but says very little. Cousin: “X, not Y.”
Example to fix:
Truly. Really. Actually. Literally. Simply. Absolutely. Fundamentally. Essentially. Ultimately. In many ways. None of these add information. They add a beat.
Example to fix:
Leverage. Utilize. Facilitate. Drive. Optimize for. Empower. Unlock. Unleash. Harness. These verbs were corporate clichés before AI showed up and they got worse from there. The replacement for “leverage” is “use.”
Robust. Comprehensive. Holistic. World-class. Best-in-class. Industry-leading. Transformative. Seamless. Scalable. Cutting-edge. Innovative. None of them mean anything specific. None of them help a reader picture what you do.
Three adjectives in a row before a noun. “A powerful, comprehensive, effective solution.” Pick one. If you can’t pick one because all three matter, the noun is probably wrong.
“In today’s fast-paced world.” “Imagine if.” “Have you ever wondered.” “Here’s the thing.” All of these are AI’s way of clearing its throat. Cut to the actual point.
“It’s important to note that.” “It’s worth mentioning.” “What’s interesting is.” If something is important, just say it. The preamble signals you weren’t sure if the next sentence would land on its own.
The sentence that takes a position then immediately balances it away. “Marketing is both an art and a science.” “It’s not about the destination, it’s about the journey.” “Success is a marathon, not a sprint.” These sentences sound profound and contain almost no information.
The variant that’s specifically AI-flavored: “X is not a Y problem, it’s a Z problem.” Real diagnosis is rarely that clean.
When every sentence in a paragraph has the same shape, it reads as a rhythm exercise rather than thought. Especially common in lists where every item starts with the same verb tense.
Example to fix:
(Same words. Different rhythm. The fragments break the AI-cadence.)
Phrases that have been used so many times in marketing copy they no longer mean anything. “Drive results.” “Deliver value.” “Exceed expectations.” “Tailored solutions.” “Vanity metrics.” “Real-world performance.” “Move the needle.” “Game-changer.”
Replace each with the specific thing you mean. “Drive results” becomes “double qualified leads in 90 days” or “cut spend 30 percent.” Specific beats sweeping every time.
Beyond individual phrases, watch for these structural patterns:
If you want this in printable form, the two-page Voice Audit Checklist has all twelve tells plus the three-step sweep on a single sheet. Free, no email.
Run this on any piece before publishing:
Step 1: The em dash sweep. Search your file for em dashes. Replace every one in user-facing copy. Use periods, commas, or rephrase. Code comments and developer-facing strings can keep them.
Step 2: The intensifier sweep. Search for: truly, really, actually, literally, simply, absolutely, fundamentally. For each match, decide if cutting the word changes the meaning. Almost always, no. Cut it.
Step 3: The triplet check. Find every “X, Y, and Z” pattern. For each, ask: does the reader need three things or am I padding for rhythm? If the third item is weaker than the first two, cut it.
That sweep alone removes most of the AI signature from a piece without forcing a full rewrite.
The patterns above are common AI tells. They aren’t banned in human writing. Don’t be paranoid:
The stakes aren’t aesthetic. They’re credibility. In 2026, founders and senior buyers are reading every piece of marketing copy with an AI filter on. They’re trained to spot the patterns above because they’ve seen them in 10,000 LinkedIn posts and inbox cold emails.
The moment a reader’s filter triggers, you go from “interesting consultant” to “another consultant who outsourced their writing to a chatbot.” You can’t unring that bell on the same page.
The fix isn’t to stop using writing tools. The fix is to use them as a draft engine and do the editing work yourself. The patterns above are your edit checklist.
The version of you that ships AI-flavored copy and the version that ships clean copy are reading the exact same writing. The difference is whether you’ve done the sweep.
If you want to see what the cleaned version looks like in practice, the rest of this site is run through this exact checklist. The free Google Ads Setup Checklist is the most extensively edited document on the site, 25 pages, multi-pass voice audit. Read it as a reference for what operator-direct voice reads like in the wild.
A version of this checklist runs as an automated linter inside the content engine I built for Emma Grace Home. Every one of its 16 draft posts went through the linter, and a draft that tripped it got rewritten before a person read it. That build is written up here.
