How to make AI-generated content not look like AI (the 7 tells to kill)

The 7 tells that flag AI content — and the prompt patterns, persona rules, and edit passes that kill each one.

Why AI content feels off

Most AI writing fails in the same 7 ways. Every tool — ChatGPT, Claude, Jasper, Copy.ai — has the same fingerprints because the base models were trained on overlapping data. Kill the fingerprints and the content reads as human.

Tell 1: hedge words everywhere

"It is worth noting that," "arguably," "in many cases," "can often," "tends to," "may." Models hedge because hedged claims are harder to prove wrong in training data. Humans who actually know the topic do not hedge.

Fix: Add every hedge word to your Persona Brief banned list. If a claim needs a hedge, either cut it or replace the hedge with a specific qualifier ("in the 4 cases I have tested").

Tell 2: the tricolon

"Fast, reliable, and scalable." "Easy to use, easy to learn, and easy to love." Three-item lists are a base-model reflex. Sprinkled occasionally they are fine. Three tricolons per paragraph is a dead giveaway.

Fix: Limit to one tricolon per 500 words. Rewrite the rest as two-item or four-item lists, or as a single punchy claim.

Tell 3: the "not just X, but Y" structure

"It is not just faster, it is fundamentally different." "This is not just a tool, it is a workflow." The X/Y escalation is the single most over-used AI sentence structure.

Fix: Ban the literal phrase "not just" in your Persona Brief.

Tell 4: over-uniform paragraph length

Models default to 3-4 sentence paragraphs because that is what Wikipedia and marketing copy look like. Human writing mixes 1-sentence punches with 6-sentence meanders.

Fix: On your edit pass, merge two adjacent short paragraphs, then split a long one. Vary length deliberately.

Tell 5: closing summary paragraphs

"In conclusion," "to summarize," "ultimately," "at the end of the day." Models close with a recap because their training data rewards it. Human writers usually close with a concrete line — a callback, a provocation, or a specific next action.

Fix: Delete any paragraph that starts with a summary word. Replace with one concrete sentence.

Tell 6: em-dash abuse

Models overuse em-dashes — like this — as a substitute for real sentence structure. Humans use em-dashes occasionally, usually for asides that would otherwise need parentheses.

Fix: Limit to 1 em-dash per 300 words. Convert the rest to periods, commas, or parentheses.

Tell 7: the "authoritative but vague" claim

"Studies show," "research suggests," "experts agree." No study, no citation, no expert. Models use this because it is a safe rhetorical pattern. It is also a giant red flag.

Fix: Every claim needs either a specific citation or a "this is my opinion, framed as my opinion" signal. No vague authority.

How Kompozy handles this automatically

Kompozy’s Persona Brief includes a banned-words list that ships with all 7 tells pre-blocked. Outputs that slip a banned phrase past the prompt-level constraint get rejected at the brand-safety gate and regenerated.

Frequently asked questions

Can AI detectors tell the difference between AI content and human writing?

Sometimes, but the results are unreliable. The bigger problem is not the detector — it is that readers feel the difference even when they cannot name it. Fix the human signal, not the detector score.

Does Google penalize AI-generated content?

Google penalizes unhelpful content, not AI content specifically. A well-edited AI-assisted post ranks fine. A thin, hedging, unsourced AI post does not, regardless of how it was written.

What is the fastest way to humanize AI output?

Cut every hedge word, vary sentence length, add one specific detail that only a human who lived the experience would know, and swap the closing summary for a concrete line.

Do I still need to edit AI content if I use a persona brief?

Yes, at least for the first 20 outputs. Every edit feeds back into the brief. After that, most outputs ship untouched.

The direct answer

AI content reads as AI because of 7 consistent tells: hedge words, tricolons, "not just X but Y" constructions, uniform paragraph length, closing summaries, em-dash overuse, and vague authority citations. Kill each one via Persona Brief banned-word lists plus a 5-minute manual edit pass per output.
