Direct Answer
Turnitin's AI detector is not a tool that students can launch independently—it is an automated feature built into Turnitin's Similarity Report that activates when a paper is submitted through an instructor-created assignment in an LMS like Canvas, Moodle, or Blackboard. To use it as a student, you submit your document to an assignment that has AI writing detection enabled by your instructor. Once processed, the AI Writing Report displays an overall percentage and highlights text segments the model predicts were AI-generated, using cyan for direct AI generation and purple for AI-paraphrased content. Whether you can view the report before your instructor depends entirely on your instructor's visibility settings; many instructors choose to keep the AI indicator hidden until after the due date or grading [1].
What Steps Do Students Need To Follow To Access And Submit To The Turnitin AI Detector?
The first step is understanding that Turnitin's AI detection is not a standalone student portal. When your instructor creates a Turnitin-enabled assignment in your institution's LMS—whether Canvas, Moodle, Blackboard, or another system—they can enable AI writing detection in the assignment settings. From a student's perspective, you submit your paper the same way you would for any Turnitin Similarity check: log in to your LMS, navigate to the assignment, and upload your file in a supported format (.docx,.pdf,.txt, or.rtf). The AI detection model then processes your submission automatically alongside the Similarity check [2].
Once submitted, Turnitin's system breaks your document into segments of roughly a few hundred words, overlapping them to capture each sentence in context. Each segment is scored between 0 and 1 for AI likelihood, and the overall prediction is calculated from the average of all segment scores [1]. The model requires at least 300 words of prose text in a long-form writing format—poetry, bullet points, code, and annotated bibliographies are not reliably detected. Files must be under 100 MB and not exceed 30,000 words [2].
After processing, your instructor sees an AI writing indicator appear in the Similarity Report sidebar. This indicator displays the overall percentage of qualifying text the model predicts was generated by an AI tool. If your instructor has enabled student visibility, you may also see the AI writing report by opening your submission and clicking the AI tab or icon next to the Similarity Report. You cannot manually "run" the AI detector on a draft outside of an official Turnitin assignment unless your institution provides alternative tools like Turnitin Draft Coach [2].
How Does Turnitin's AI Writing Report Display Scores And Highlight Flagged Content?
The AI Writing Report presents its findings through a clear percentage score at the top of the report, followed by a visual submission breakdown that categorizes detected text into two distinct groups. The first category, "AI-generated only," appears in cyan and highlights text that the model believes was produced directly by a large language model such as GPT-4, Claude, Gemini, or LLaMA. The second category, "AI-generated text that was AI-paraphrased," appears in purple and flags content that was likely AI-generated and then passed through a paraphrasing tool like Quillbot [2].
An important design feature of the report is how it handles low-confidence scores. Turnitin's testing has found a higher incidence of false positives when the detection percentage falls between 0 and 19 percent. To reduce the risk of misinterpretation, any score below 20 percent displays as an asterisk (%) rather than a specific number. This means that as a student, if you see % on your report, it could mean either 0 percent detected or a low single-digit result that the system treats as inconclusive. Only scores of 20 percent or higher appear as exact percentages [2].
The report also includes an interactive submission breakdown bar that gives a page-by-page visual overview of where AI-generated and AI-paraphrased text appears in your document. You can click on each colored segment to jump directly to the corresponding page and passage. It is critical to note that the AI writing detection percentage is independent of the Similarity score—a paper can have a high AI percentage and a low similarity percentage, or vice versa, because the two models analyze entirely different characteristics of the text [1]. Turnitin emphasizes that the AI indicator should not be used as the sole basis for any academic judgment, and it provides the data only as a starting point for instructors to have informed conversations with students [3].
Can Students Check Their Turnitin AI Score Before Their Instructor Sees The Report?
This is one of the most common questions students ask, and the answer depends entirely on your instructor's configuration of the assignment. Within Turnitin's standard assignment workflow, students generally cannot self-initiate an AI check on a draft without submitting it to an official assignment. The AI writing detection report becomes available only after your paper has been uploaded and processed by Turnitin through an instructor-created assignment that has AI detection enabled [1].
Your instructor has full control over when—or if—the AI writing report becomes visible to you. In the assignment settings, they can choose to make the report available immediately after submission, after the due date, after grading, or never. Some instructors set up practice or draft assignments specifically to allow students to see their AI and similarity scores before the final deadline. If your instructor has enabled this, you will see the AI indicator and report when you open your submission in Feedback Studio. If they have not, you will only see the Similarity Score without any AI detection information [2].
For students who want to preview their AI score before submission, a practical alternative exists outside the institutional system. Services like Turnitin0.com provide official-level Turnitin AI and similarity reports that match what professors see in their academic systems. This allows you to check your document beforehand, understand how much of your writing appears AI-generated to Turnitin, and make informed adjustments before submitting to your actual assignment. Turnitin's own documentation notes that students cannot self-check within Turnitin without an instructor-created assignment, making third-party preview services a valuable option for proactive academic planning [4].
After previewing your AI score independently, you can walk into your actual Turnitin assignment with confidence—knowing exactly what your professor will see and having already addressed any flagged sections.

FAQ
Q1: Do I need to install any software to use Turnitin's AI detector as a student?
No. Turnitin's AI writing detection works entirely within your institution's LMS. You submit your document through a standard Turnitin assignment link provided by your instructor, and the detection runs automatically on Turnitin's servers. No downloads or browser extensions are required [1].
Q2: What file types can I submit for AI detection?
Turnitin accepts.docx,.pdf,.txt, and.rtf files for AI writing detection. The document must contain at least 300 words of prose text in a long-form writing format and be under 100 MB in size. Documents exceeding 30,000 words or consisting primarily of bullet points, tables, or code will not generate a reliable AI report [2].
Q3: Can my instructor see my AI score before I can?
Yes. By default, the AI writing indicator is visible only to instructors and administrators. Your instructor chooses whether to make the AI report available to you—and when. They may enable student visibility immediately, after the due date, after grading, or not at all. This is an important factor to clarify with your instructor early in the semester [1].
Q4: What does it mean if my AI score shows *% instead of a number?
An asterisk score (*%) means the detection percentage is below 20 percent. Turnitin displays this asterisk to reduce misinterpretation of low-confidence scores, as false positives are more likely in the 0–19 percent range. Your paper may have 0 percent AI-detected text, or a low single-digit result. Only scores of 20 percent or higher appear as exact percentages [2].
Q5: If I rewrite my essay after seeing the AI report, will the score change?
Yes. The AI writing detection model analyzes the text that is currently submitted. If you revise your document—rewriting flagged passages in your own voice, restructuring sentences, or adding original analysis—and resubmit (if your assignment allows resubmissions), the AI detection will reprocess the new text and generate an updated score. Turnitin Classic assignments allow up to 3 immediate resubmissions, with a 24-hour wait for subsequent attempts [4].
