What is it?

In April 2023 Turnitin released an AI detector score that has been added to the current grading features (below the Similarity Report). At this time, only instructors can see the AI detection score; students do not see the score even if the instructor enables them to see the similarity report.

Advancements over time

Turnitin most likely will adjust the AI detector as advances are made in AI (such as with the popular ChatGPT), however, AI is developing at such a rapid pace that instructors should accept the AI detector score with some skepticism since false positive results are possible.

Please note that the first time you attempt to grade a submission Turnitin will prompt you with a pop-up “tour” of the product, but you may miss out on some valuable resources if you just dismiss it. Within the tour, Turnitin has references to the company’s own assignment checklist and rubric that some may find helpful for designing assignments that may deter the use of AI-generated submissions.

Finding the AI Score

You will view the AI score on the originality report in a new blue box. Remember, this is not visible to students.

AI Score in Turnitin

In addition to a score, which indicates the amount of qualifying text within the submission that Turnitin’s AI writing detection model determines was generated by AI, you will also see text highlighted; highlighted text indicates the parts of the document flagged as AI generated. This is similar to the Similarity Report which highlights text that is taken from other sources.
