Turnitin has introduced an AI writing detection feature to help educators 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 checker in Turnitin effectively to maintain academic integrity and understand the results it provides.
Accessing the AI Checker in Turnitin
The AI checker is integrated into the Turnitin Similarity Report , available for institutions using Turnitin Feedback Studio, GradeScope, or Similarity Report v2 .
Steps:
- Log in to your instructor account on Turnitin.com or through your LMS (e.g., Canvas, Blackboard).
- Open a student submission to view the Similarity Report .
- Look for the “AI Writing” percentage displayed at the top of the report.
- Click into the report to see highlighted sections where AI writing is detected.
Understanding the AI Detection Report
Turnitin’s AI checker does not provide a definitive yes/no answer but gives a probability score indicating how likely it is that a piece of text was generated by AI.
Key Elements:
- AI Writing Percentage : A score from 0% to 100%, estimating how much of the paper was likely AI-generated.
- Highlighted Sections : Text segments marked with yellow or orange shading indicate potential AI involvement.
- Reasons for Detection : Turnitin analyzes patterns such as sentence structure, vocabulary consistency, and fluency — traits common in AI-generated text.
Best Practices for Using the AI Checker
While Turnitin’s AI detection tool is powerful, it should be used as a supportive resource , not the sole determinant of misconduct.
Tips:
- Review Results Critically : Use the AI score as a starting point, not proof. Always read the paper and consider context.
- Combine with Plagiarism Report : Check both the Similarity Index and AI Writing Score for a full picture.
- Talk to Students : If AI use is suspected, discuss the work with the student to assess understanding and writing style.
- Set Clear Policies : Inform students about acceptable 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, the tool currently works best with English-language submissions and may have reduced accuracy with non-native writing styles.

Q1: Can Turnitin detect all AI-written content?
No. While Turnitin uses advanced models to detect AI-generated text, some AI-assisted or heavily edited content may go undetected.
Q2: Does Turnitin tell me if a student cheated?
Not directly. The AI checker identifies likelihoods, but educators must interpret the results alongside other evidence.
Q3: Is the AI checker available for all Turnitin users?
The AI writing detection feature is available to institutions with eligible licenses. Contact your Turnitin admin for access details.
