Direct answer
When a paper is submitted through Turnitin, instructors receive two documents that shape how the work is reviewed: the Similarity Report and the AI writing report. The Similarity Report matches text against a large database of published and student work, while the AI writing report estimates how much of a submission may have been generated by AI tools [1]. Together, these two outputs are commonly referred to as "Turnitin reports." Understanding what they show—and what they do not—is the first step to reading your own results accurately.
What Exactly Is a Turnitin Report and What Information Does It Contain?
A Turnitin AI writing report is produced for each submission when the feature is enabled, and it gives instructors a percentage plus sentence-level highlights of text judged to have been written by an AI tool [2]. Rather than a vague verdict, the report groups flagged content into categories such as AI writing, AI paraphrasing, and mixed human/AI patterns, so the reviewer can see which passages contributed to the overall score [2].
The second key component is the report's evidence view. Instructors can open flagged sentences to inspect the specific segments the model believes were machine-generated, which is why the report is designed as a starting point for discussion rather than a standalone accusation [2]. This distinction matters for students because a Turnitin report never declares "this paper was written by AI"—it identifies suspicious portions that require an instructor's judgment.
The Similarity Report works on a different principle: it measures textual overlap between your paper and Turnitin's index of web pages, academic publications, and previously submitted student work, then shows a similarity percentage with links to the matching sources. Where the AI writing report addresses authorship and generation, the similarity report addresses copying and unattributed reuse, and instructors typically review both side by side. Knowing which report answers which question prevents you from confusing a high similarity score with an AI detection flag.
How Does Turnitin Calculate and Display Similarity and AI Writing Scores?
Turnitin's AI detection model analyzes writing patterns that are statistically common in machine-generated text, such as uniform sentence structure and predictable phrasing, and it returns a percentage representing the portion of the submission it believes was AI-written [3]. The same score carries a confidence indicator so instructors understand whether the model's assessment is strong enough to act on or merely suggestive [3].
One display rule frequently surprises students: in the AI writing report, any score below 20 percent is displayed as an asterisk (*%) rather than as a concrete number such as 3% or 12% [3]. The only low numeric value a student typically sees is an explicit 0%; otherwise the asterisk bucket is used, which is why "below 20%" and "0%" are the two outcomes most often discussed in student communities. Similarity scores use their own color-coded bands—blue for no matches, then green, yellow, orange, and red as the percentage climbs—so both reports rely on ranges and indicators rather than raw numbers alone.
These calculation and display rules apply consistently because the same report your instructor opens is the same report you can preview before submitting. That consistency is what makes pre-submission checking useful: if your own report shows an asterisk score or flagged sentences, the institutional copy your professor receives reflects the same model output [3]. Scores are reproducible outputs of one detection system used across institutions, not arbitrary judgments.
Can Students Check Their Own Turnitin Reports Before Submitting to Their Institution?
Whether students can check their own reports depends entirely on how their institution has configured Turnitin. Some universities enable draft assignments that generate reports before the final submission deadline, while others restrict reports to instructors only, leaving students unable to preview their own results [4]. That is why so many students look for an independent way to see the exact report their instructor will receive.
Checking before submission matters because both reports feed directly into academic-integrity decisions. A student who reviews their AI writing report early can see which passages were flagged and decide whether to revise, rewrite, or discuss the flagged text with their instructor before the final grade is affected [4]. Early visibility turns a report from a surprise into an actionable preview.
In practice, a pre-submission check only helps if it reproduces the institutional view: the same scoring model, the same percentage display rules, and the same flagging behavior. When students use a checking service that mirrors what professors see in their academic systems, the report they review is the report that will be evaluated, eliminating the gap between preparation and outcome [4].
The fastest way to see exactly what your instructor will see is to generate a real Turnitin report for your draft before you submit. turnitin0 delivers genuine Turnitin similarity and AI writing reports—with the same cover, percentage display, and sentence-level flags used in institutional systems—so you can review your results with confidence instead of guessing.

FAQ
What is the difference between the similarity report and the AI writing report?
The similarity report measures how much of your text matches published or previously submitted sources, while the AI writing report estimates how much of your text may have been generated by AI tools [1]. One addresses copying and attribution; the other addresses authorship and generation.
Why does my Turnitin AI score show as *% instead of a number?
Turnitin displays any AI writing score below 20 percent as an asterisk (*%) rather than as a single-digit number such as 3% or 12% [3]. The only explicit low numeric score students typically see is 0%; otherwise the asterisk bucket is used.
Do instructors use the AI writing report as proof that a student cheated?
No. The report is intended as a starting point for discussion, because the detection model identifies portions that may have been AI-written and assigns a confidence indicator rather than a definitive verdict [2]. Instructors are expected to review flagged text and speak with the student before making a determination.
Can I check my draft and see the same report my instructor would receive?
Yes, if you use a service that runs the real Turnitin system and its display rules. Turnitin0 generates genuine Turnitin similarity and AI writing reports—the same cover, percentage display, and flags seen in institutional accounts—so the report you preview matches what your professor would see.
How long does it take to receive a Turnitin report after submitting a document?
With Turnitin0, reports are typically delivered within 5–10 minutes, and in the vast majority of cases delivery is guaranteed within 30 minutes. Your paper is not archived or sent to any third-party database, so checking a draft early is both fast and private.
