Student or AI bot? New ChatGPT writing detectors can get it wrong.

After months of sounding the alarm about students using AI apps that can churn out essays and assignments, teachers are getting AI detection technology of their own. On April 4, Turnitin is activating the software I tested for some 10,700 institutions including the University of California, assigning "generated by AI" scores and sentence-by-sentence analysis to student work. It joins a handful of other free detectors already online. For many teachers, AI detection offers a weapon to deter a 21st-century form of cheating.
