On 16 July, Turnitin will upgrade its AI writing detection feature to include a new paraphrasing detection capability. This enhancement will help identify instances where paraphrasing tools have been used to modify AI-generated text in student submissions. The detection will run automatically for all assessments submitted to Turnitin LTI assignments. Therefore, there is no need to update your reassessment submission points to have access to the AI paraphrasing detection tool.
How does it work?
Student-submitted content that may have been modified using an AI paraphrasing tool will be flagged as likely AI-generated in the AI writing report. The report will highlight text that Turnitin’s model predicts was likely written by an AI tool in a different colour from content that was likely AI-written and subsequently modified using an AI paraphrasing tool, to distinguish between them.
Turnitin will not differentiate between likely AI-paraphrased matches and likely AI-generated text in the AI writing report. However, as Turnitin continues to develop and improve this feature, their aim is to include such differentiation in the future.
Will it detect grammar-checking tools?
Turnitin’s paraphrasing detection tool is not designed to target grammar-checking tools like Grammarly, which modify spelling, grammar, and punctuation, but rather other AI content written by large language models (LLMs) such as GPT-3.5.
Information for students
The University has produced guidance that has been made available to students about Contract Cheating, Academic Integrity, and Using AI at University. Furthermore, it is important to reassure students that ‘Turnitin evidence is always interpreted by academics and used in context, to supplement judgement rather than to replace it’ (Turnitin’s artificial intelligence detector tool).
