"What if you could eliminate 80% of your busywork by this afternoon? Most people don't realize it's possible."

Human rewrite

"The question I kept asking in 2023 was the wrong question. I didn't realize that until 2025."

Model: ChatGPT / Open-source LLMs  ·  Frequency: Moderate

Structure

• Three or more consecutive sentences under 12 words
• Each sentence makes a distinct declarative claim
• Final sentence is the punchline or pivot

AI example

"Speed matters. Clarity matters more. Together, they are unstoppable."

Human rewrite

"Fast is fine. Clear is better. Both at once is genuinely rare."

Model: All models  ·  Frequency: High

Structure

• "This isn't just X." or "Don't have a problem with X."
• Reframe: "They have a problem with Y."
• Expansion of the real issue

AI example

"This isn't a time management problem. It's an energy management problem."

AI example

"The best investment you can make is in the people around you."

Human rewrite

What are AI sentence patterns?

AI sentence patterns are named cadence templates that appear at elevated rates in AI-generated text. They are distinct from vocabulary signals: a cadence pattern is identified by the repeating shape of a sentence or passage — its rhythm, structure, and progression — rather than specific words. The Bloomberry AI Sentence DNA corpus catalogs 12 structural cadence detectors alongside vocabulary markers, hook patterns, and phrase-level clichés.

Why do AI sentence patterns matter more than individual banned words?

Vocabulary bans address surface signals but leave deeper structural patterns intact. A piece of writing can avoid every word on a banned list and still feel AI-generated because the cadence — the rhythm and progression of sentences — follows the same structural blueprint. Pattern stacking is particularly diagnostic: when multiple cadences appear together in one post, the compound signal becomes hard to dismiss.

Are these patterns unique to AI writing?

No. Human writers use these patterns too, and AI writing avoidance systems cannot treat any single pattern as definitive. These patterns are diagnostic because they appear at statistically elevated frequencies in AI-generated text relative to equivalent human-authored content. They are writing signals, not authorship determinations.

How many sentence patterns does Bloomberry track?

The AI Sentence DNA corpus includes 12 named structural cadence detectors. These are separate from the 17 named hook patterns, the phrase-level cliché list, and the vocabulary marker list. Together, these four categories form the measurable signal taxonomy.
