Is this just a list of words to avoid?
No. Word-lists go stale fast (the book explains why “delve” already backfires). It teaches the underlying habits, structure, rhythm, specificity, stance, so your writing reads human even as the models change.
Field guide
The Complete Encyclopedia of AI Writing Tells. 150+ ways machine-written text gives itself away, each one paired with the specific fix. Independently fact-checked, current to 2026, and written for people whose work has to read human, not machine.

The problem
The internet is drowning in AI slop. The em-dashes. The “in today’s fast-paced world.” The rule of three, every single time. The tells are real, but the guides that list them are usually written by AI, half the “facts” are made up, and the words they warn you about changed six months ago. This is the opposite: a working field guide where every tell comes with a fix, and every number comes with a real source.
What is inside
Why trust it
Most “spot the AI” content is itself AI, unsourced, and already out of date. This edition is the opposite. Every empirical claim was verified before it shipped. Where a popular tell stat could not be traced to a real source, it was cut. Where the research was real, it is cited and linked. That is the difference between this and the free listicles: you can trust what is in it.
Every statistic sourced or cut
Current to the 2026 model lineup
Honest about the limits: no single tell is proof
Who it is for
Ghostwriters and freelancers who cannot afford to read like a template. Editors and content leads auditing a team’s output. Marketers who want copy that converts because it sounds like a person. Anyone tired of their own drafts reading like a press release.

No. Word-lists go stale fast (the book explains why “delve” already backfires). It teaches the underlying habits, structure, rhythm, specificity, stance, so your writing reads human even as the models change.
It helps you write like a human, which is the only durable answer. Read the detector chapter first: it explains, with sources, why detectors are unreliable and why no score is ever proof.
The first draft was, and that is the point. It was then torn apart and independently fact-checked: fabricated stats cut, real citations added, brought current to 2026. The audit trail is part of what you are buying.
