Direct Answer – Turnitin does not offer a public portal where students can look up their AI or similarity score by entering a submission ID or reference number alone. The submission ID or receipt number you receive after submitting an assignment is primarily a tracking identifier within your institution's learning management system (LMS). To view your Turnitin AI writing report and similarity score, you must access the assignment through your institution's LMS (such as Canvas, Blackboard, or Moodle), and your instructor must have made the report visible. For students who want the certainty of knowing their scores before submitting to the institution, third-party pre-checking services provide a practical alternative [1].
How Does Turnitin Generate an AI Score in Its Writing Report?
Turnitin's AI writing detection model evaluates submitted text by analyzing two key linguistic dimensions: perplexity and burstiness. Perplexity measures how predictable or surprising each word choice is—AI-generated text tends to be more predictable, with lower perplexity, while human writing typically shows greater variability. Burstiness captures the natural variation in sentence length and structure; human writing tends to alternate between longer, complex sentences and shorter ones, whereas AI-generated text is often more uniform [2].
The detection engine processes the document in segments, assigning each sentence or paragraph a "probability of AI generation" score. For the overall document, Turnitin displays a percentage: 0% indicates no detectable AI-written text, *% (asterisk) means the score is below 20% and is intentionally masked into a single low bucket, and scores from 20% to 100% are shown as exact percentages. Instructors also see highlighted segments in the AI writing report that indicate which passages are flagged as likely AI-generated, allowing them to review those sections in context [2].
It is important to understand that the AI detection score is probabilistic, not definitive. Turnitin itself advises instructors to use the score as one data point among many, and to exercise professional judgment before drawing conclusions about academic integrity. The model is trained on a large corpus of academic writing and AI-generated text, and while it is highly accurate, false positives or ambiguous results can still occur [2].
Can Students Access Turnitin AI Reports Using a Submission ID After Submitting to Their Institution?
Students do not have a standalone public portal where entering a submission ID or reference number retrieves their Turnitin AI report or similarity score. The submission ID you receive after uploading your file is used internally by Turnitin and your institution's LMS for tracking purposes—it is not a valid key for independent score lookup [3].
Instead, accessing your Turnitin reports requires logging into your institution's LMS (Canvas, Blackboard, Moodle, or others), navigating to the specific assignment, and opening the Turnitin submission tray. The AI writing report and similarity report become visible only if your instructor has configured the assignment to show them. In many cases, instructors may choose to keep the AI report hidden until after they have finished grading, or they may not enable the AI detection feature at all. If you cannot see a report, it does not necessarily mean there is no detection—it may simply mean the instructor has not yet released the results [3].
For students who want to see their scores with certainty, relying on post-submission LMS access can be frustrating. The lack of a direct submission-ID–based lookup means that once you hit "submit," you have limited control over when and how you receive your Turnitin feedback [3].
What Can Students Do If They Want to Check Their Turnitin AI Score Before Submitting to Their Institution?
Turnitin does not offer an official self-check portal where students can upload a draft and receive an AI or similarity score directly. The Turnitin detection and similarity reports are designed for institutional use, which means students typically only see them after submission and at the instructor's discretion. This creates a gap: students who want to know whether their work will be flagged before they formally turn it in have no official pre-check tool [4].
To bridge this gap, many students turn to pre-submission checking services that replicate the Turnitin institutional experience. These services allow students to upload their documents (.docx,.pdf, or.txt) and receive both a similarity/plagiarism report and an AI writing detection report—matching what professors see in institutional Turnitin systems. Results are typically delivered within minutes, and the report includes the overall AI percentage, highlighted flagged segments, and the similarity match breakdown [4].
Pre-checking your work serves two important purposes: it gives you an accurate preview of what your instructor will see, and it offers an opportunity to revise or cite any flagged content before final submission. Instead of waiting anxiously after submitting to your institution, you can know your scores in advance and make informed decisions about your draft. Services like Turnitin0 provide exactly this capability, with reports processed within 5–10 minutes in most cases [4].
Checking your Turnitin score before submitting to your institution gives you full control and peace of mind. With Turnitin0, you can preview the exact same AI writing report and similarity report that your professor would see—complete with an AI percentage score, flagged segments, and a full similarity breakdown—without waiting for your instructor to release results. No subscriptions, no long waits, just the real Turnitin reports you need to submit with confidence.

FAQ
1. Can I check my Turnitin score with just my submission ID?
No. Turnitin does not provide a public lookup portal where a submission ID alone retrieves your AI or similarity report. The submission ID is an internal tracking number; to view your scores you must log into your institution's LMS and access the assignment directly [1][3].
2. Why can't I see my AI report in Turnitin even though I submitted successfully?
Your instructor must have enabled the AI writing detection feature and configured the assignment to make the report visible to students. Some instructors choose to release reports only after grading, or may not use the AI detection feature at all [2][3].
3. What does the asterisk (*%) mean in my Turnitin AI score?
The asterisk (*%) indicates a Turnitin AI score below 20%. Turnitin intentionally masks single-digit scores (1%–19%) into this single bucket, meaning you only know it is under 20% but not the exact number. The only explicit low numeric score shown is 0% [1][2].
4. Can I get a Turnitin report before submitting to my university?
Turnitin does not offer an official pre-submission self-check tool for students. However, third-party services like Turnitin0 allow you to upload your document and receive the same institutional-style AI and similarity reports within minutes, giving you a reliable preview before your final submission [4].
5. If my Turnitin AI score shows *%, does that mean my paper is safe?
A score of *% (below 20%) suggests low probability of AI generation, but it is not a guarantee. Turnitin's AI detection is probabilistic, and instructors are trained to use the score along with other evidence. It is always wise to review any flagged segments and ensure proper attribution and original writing [1][2].
