This is not one study or one anecdote. The evidence on AI detectors and ESL writers has piled up, and it points one way. Here is the data, the honest range in it, and what it means for you when your correct, human writing gets flagged as machine.
A detector calls your own academic writing AI. The problem is not your honesty. Formal academic conventions produce the exact predictability detectors punish. Here is the mechanism, and how to lower a false flag without erasing your voice.

ChatGPT outputs smoother English than you do. That feeling is real, and the math behind it is mechanical, not personal. The post explains why fluency was never the value you sold, and what was.
You wrote every word yourself. The detector says 94% AI. You're not imagining it, you're not doing anything wrong, and you're not alone — Stanford research shows non-native writers get flagged at over five times the rate native speakers do. Here's what's actually happening and what works.

Your writing sounds non-native and you can't figure out why. Here are 7 specific patterns that give it away — with real examples and simple fixes for each one.
