Turnitin has introduced an AI writing detection feature to help educators and institutions identify content that may have been generated or assisted by artificial intelligence tools like ChatGPT , Gemini , or Claude .
Here’s how to use the AI detector on Turnitin effectively in 2025 to ensure originality and uphold academic standards.
Step 1: Submit or Access the Paper in Turnitin
To use the AI detector:
- Log in to your Turnitin Feedback Studio , GradeScope , or LMS-integrated Turnitin account (e.g., Canvas, Blackboard)
- Navigate to the assignment where the student paper was submitted
- Open the submission to view the Similarity Report
Note: The AI detection feature is available only for institutions with eligible licenses. Contact your admin if you don’t see the option.
Step 2: Locate the AI Writing Detection Section
Once inside the Similarity Report , look for the AI Writing indicator — usually displayed at the top of the report alongside the overall similarity score.
What You’ll See:
- A percentage from 0% to 100% , estimating how much of the paper was likely written by AI
- Highlighted sections within the text marked in yellow or orange , indicating possible AI involvement
Step 3: Understand the AI Detection Report
Turnitin’s AI checker does not provide a definitive yes/no answer but gives a probability score based on linguistic patterns commonly found in AI-generated text.
Key Elements:
- AI Writing Percentage : Shows the estimated portion of the paper that may be AI-generated
- Highlighted Text : Specific paragraphs or sentences flagged for AI-like structure and fluency
- Reasons for Detection : Includes analysis of sentence complexity, repetition, and vocabulary consistency
The system currently works best with English-language submissions , though support for other languages is expanding.
Step 4: Review Results Critically
While Turnitin’s AI detection tool is powerful, it should be used as a supportive resource , not the sole determinant of misconduct.
Best Practices:
- Read the full paper and consider context before making judgments
- Combine with the plagiarism report for a complete picture of originality
- Talk to the student to assess their understanding and writing style
- Set clear policies about AI use in your course before submitting work
Limitations of Turnitin AI Detection
It’s important to understand what the AI checker can and cannot do:
| Flag text with high probability of being AI-generated | Confirm 100% whether AI was used |
| Analyze large volumes of text quickly | Detect paraphrased or edited AI content reliably |
| Provide breakdowns of AI-generated sections | Identify which AI tool was used |
Also, some AI-assisted or heavily edited content may go undetected.
