Section 1
The premise
Tools like GPTZero and Turnitin's AI detector flag legitimate human writing as AI ~10-30% of the time, with worse rates for non-native English writers.
What AI does well here
- Flag clearly machine-generated boilerplate sometimes.
- Update as new models emerge — but always behind.
- Provide a probability score, not a verdict.
- Detect heavy paraphrasing of known training data occasionally.
What AI cannot do
- Reliably tell human from AI — error rates are too high to be actionable.
- Distinguish 'AI-assisted edit' from 'AI-written' meaningfully.
