AI Detector
Definition
Software that claims to tell whether writing was produced by AI. Most of these tools guess from writing style. They cannot see how much of the work a person did before asking a chatbot to polish, translate, or tidy the sentences. A high "AI" score is not proof of cheating. A low score is not proof a human wrote it.
Why It Matters
Schools and workplaces are treating these scores like a verdict. I would like the word to mean what it can actually do — which is guess — before anyone's paper or email gets waved away.
What does that look like in practice?
Your granddaughter writes the history paper herself, then asks a chatbot to fix the grammar because English is her second language. A detector flags it. Meanwhile a classmate who pasted a lazy AI draft and rewrote every sentence by hand might sail through. The tool saw style. It did not see the work.
What people actually mean when they say this
People say "the detector caught it" as if it were a fingerprint. Usually they mean a probability score from a guessing tool. They also mix this up with AI watermarking — a hidden mark some labs weave into generated text — which is a different, also-limited signal, not a lie detector either.
