Turnitin has an AI writing indicator included in the Similarity Report. It shows an overall percentage of the document that AI writing tools, such as ChatGPT, may have generated. The indicator further links to a report which highlights the text segments that the Turnitin model predicts were written by AI. The model is trained on a representative sample of data spread over a period of time, that includes both AI generated and authentic academic writing. Please note, only instructors are able to see the indicator.
Turnitin does not make a determination of misconduct, rather it provides data for the educators to make an informed decision based on their academic and institutional policies. The percentage on the AI writing indicator should not be used as the sole basis for action or a definitive grading measure by instructors.
