Turnitin: How the plagiarism detection tool claims to identify ChatGPT-generated texts

Turnitin has become a key player in the academic world, offering institutions a way to uphold integrity in student work. As universities face new challenges brought on by AI, Turnitin now claims to detect content generated by tools like ChatGPT. But how exactly does this tool work, and why has it become such a crucial part of academic life?

How Turnitin detects plagiarism and AI-generated text

Turnitin works by comparing submitted documents against an enormous database of academic and online content, including books, articles, student papers, and web pages. If similarities are found, the system generates a similarity report that helps educators assess potential plagiarism.

The platform has evolved over the years, integrating tools like Feedback Studio and Turnitin Originality. These services combine plagiarism detection with tools for grading and commenting, streamlining the evaluation process while promoting better student writing.

Since 2014, Turnitin has invested in artificial intelligence to refine its capabilities. With the rise of generative AI, the company now claims its tools can flag text that shows patterns consistent with AI generation, particularly from models like ChatGPT. This is done through proprietary algorithms that analyze phrasing, structure, and predictability.

Why Turnitin matters more than ever

Academic institutions are under pressure to maintain rigorous standards, especially as students increasingly turn to AI tools. Turnitin provides a safeguard against misuse, helping educators detect unoriginal or AI-written content that undermines learning and critical thinking.

By combining similarity checking with AI detection, Turnitin positions itself as a defender of academic honesty in the digital age. Its tools aim not just to catch rule-breakers, but to encourage better habits in research and writing.
