Whether you are a teacher, editor or recruiter, spotting AI text matters. Here is how to do it well, and where the traps are.

Method 1 — Detection tools

Run the text through GPTZero, Originality.ai or ZeroGPT. They score perplexity and burstiness — how predictable and evenly paced the text is. Use the score as a hint, not proof.

Method 2 — Read like a human (more reliable)

AI writing has tells:

  • Generic structure: identical paragraph lengths, five-point lists, ‘In conclusion’ closers.
  • No specifics: claims without names, numbers or examples.
  • Flat voice: smooth but forgettable, no strong opinion.
  • Weasel hedging: ‘It is important to note…’ with nothing at stake.
  • Fact drift: confident but wrong details.

Pair this with our guide to spotting AI content.

Method 3 — The conversation test

Ask the writer to explain a key claim or show their drafts. A human who wrote it can; a copy-paste bot cannot.

The limits

  • Edited or paraphrased AI text fools detectors.
  • Non-native English and careful humans get false positives.
  • No tool is admissible as proof.

FAQ

Are detectors accurate? About 80–95% on clean text; much lower on edited or translated text.

What is the best signal? A human conversation about the work — more reliable than any score.

Should schools ban AI? Better to teach its use and verify understanding than to police blindly.

Verdict

Detecting AI text is a human skill backed by tools, not a tool alone. Score it, then read it, then talk to the author. That triple check beats any single detector.
