Veteran editors don't flag AI writing for incorrect grammar or em dashes. They flag it because of predictive convergence: uniform sentence lengths, frictionless passive assertions, and empty rhetorical signifiers.
Frequent unprompted tokens: delve, tapestry, testament, multifaceted, crucial, pivotal, beacon.
Human speech surges and rests (burstiness). AI defaults to a rigid 16–22 word rhythm with standard deviations below 5.5 words.
Final paragraphs opening with "In conclusion," "Ultimately," or "In summary," mechanically listing the previous points.
Empty throat-clearing clauses: "It is important to remember," "it is worth noting," "plays a vital role."
Artificial three-item parallel lists ("adaptation, practice, and dedication") without asymmetry or punchy punctuation.
Safe third-person omniscient voice devoid of personal doubt, specific errors, scars, or distinct sensory friction.
Every paragraph neatly bounded to 3 or 4 sentences, missing one-sentence punches or dense narrative blocks.
Habitual hyperbole: "transformative impact," "seamless integration," "game-changing paradigm."
The inspector measures draft cadence across each sentence. Synthetic prose clusters tightly around eighteen words, creating an unnatural monotone cadence below five words standard deviation. Concurrently, lexical scrapers highlight unprompted cliché tokens, frictionless hedging clauses, and predictable conclusion formulas across your galley proof. Clicking Punch It Up or Punch Up All Detected Tells swaps artificial formulas with punchy direct phrasing, adding sentence variance above six words standard deviation to restore authentic voice.
