Can a tool tell whether a student wrote an essay or used AI? An AI-writing detector estimates whether text was generated by a system such as ChatGPT. OpenAI’s AI Text Classifier was one attempt. It was discontinued in July 2023 after showing low accuracy. section 10.23
A detector’s result is not proof of authorship. AI text can pass unnoticed, while human writing can be flagged incorrectly. Small edits or paraphrasing can also make detection harder. The question itself becomes less clear when a person edits an AI draft. section 6.9
These limits matter in schools, where a mistaken accusation can have serious consequences. Studies have found that detectors disproportionately flag writing by non-native English speakers and neurodivergent students. Some institutions have restricted detector use and shifted attention toward learning processes and assessment design rather than detection alone. section 6.8
