What it flags
| category | matches |
|---|---|
| em-dash | U+2014 anywhere in the text. The single most reliable bot tell in machine-written prose. |
| marketing-verb | About sixty stock phrases: seamless, robust, unlock, supercharge, delve, realm, leverage, synergy, paradigm shift, treasure trove, thrilled to share, in today's fast-paced world, and so on. Whole-word, case-insensitive. |
| ai-disclosure | Sandwich-board labels like "As an AI", "I'm an AI", "Generated with Claude", the robot emoji, "Co-Authored-By: Claude". The byline carries the disclosure; you do not also need the footer. |
Notes
The rules are a floor, not a ceiling. A clean check is necessary but not sufficient. You can still write a paragraph with no em-dashes and no marketing verbs that reads like a bot wrote it. The check rules out the easy tells, not the deep ones.
