Direct answer
"TurnitinTM" is simply the trademarked brand name of Turnitin, LLC written with the trademark symbol attached — it is not a separate product, tier, or tool [1]. The same company behind that name licenses similarity checking and AI writing detection to universities, and both features appear inside the instructor's Turnitin account [1]. So when your syllabus says "submitted via TurnitinTM," it means your work goes through Turnitin's licensed similarity and AI detection systems, not some distinct "TM edition" [1].
What Does TurnitinTM Actually Mean, and Is It the Same Turnitin My University Uses?
Yes — TurnitinTM and the Turnitin your instructor uses are the same service; the "TM" is a trademark notation, not a product variant [2]. The brand covers a family of features delivered under an institutional licence, including the Similarity Report and the AI writing indicator that sit inside the instructor's feedback studio [2].
The Similarity Report is the part most students recognise. It generates a percentage that reflects text matched against the institution's comparison sources, and that percentage is explicitly not a plagiarism verdict — it is a signal an instructor interprets [2]. Reports are tied to the institution's licence and to the specific assignment settings, so repository inclusion and exclusion rules can change what your report shows [2].
Because everything runs under one licence, the name you see printed in a policy document, a submission receipt, or a report footer all points back to the same Turnitin platform [2]. If a third-party site uses the Turnitin name, that is a separate commercial entity and not the institutional product itself [2].
What Does Turnitin's AI Writing Detection Actually Flag in a Student Paper?
The AI Writing Report presents an overall percentage alongside sentence-level highlighting of the passages the model judges likely AI-generated [3]. That highlighting is what instructors actually read, because it localises the suspected text rather than just naming a number [3].
Turnitin frames the output as a probability estimate rather than proof, and its own guidance says results should be interpreted with context and human judgement [3]. Reliability drops for short passages, heavily edited prose, and text that falls below the model's confidence threshold — in those low-confidence cases Turnitin displays an asterisk (*%) instead of a precise figure [3].
In practice this means two students can submit similar drafts and see different treatment, because the indicator responds to sentence-level patterns rather than to a single global rule [3]. The report is designed to open a conversation about authorship, not to close one automatically [3].
Can I See My Own Turnitin AI and Similarity Report Before I Submit?
Usually not through your university account. Turnitin's own guidance explains that the AI indicator is surfaced to instructors, and students generally cannot run a self-check inside the institutional Turnitin account [4]. Whether students may preview any part of a report is set by each institution's own policy, and many do not grant access to the AI report at all [4].
That gap is why pre-submission checking matters. Because the AI score is a probability estimate that shifts with wording, revision, and length, seeing your own draft's result before the graded deadline lets you rewrite flagged passages while you still can [4]. Waiting until after submission converts a fixable writing problem into an academic-integrity conversation [4].
Students who want that preview typically use an independent checking service that runs the same style of AI and similarity reports outside the institutional account, so they can review the flagged sentences and revise before the real submission [4]. The value is not the number itself — it is the chance to act on it early [4].
If you want to see what Turnitin would actually show before your deadline arrives, turnitin0 gives you the same style of AI and similarity reports on your own draft — so you can read the flagged sentences, fix them, and submit with confidence instead of hoping.

FAQ
Is TurnitinTM a different product from Turnitin?
No. The "TM" is the trademark symbol attached to the brand name Turnitin, so "TurnitinTM" and "Turnitin" refer to the same company and platform [1]. There is no separate "TM" edition, licence tier, or detector.
Does Turnitin's AI detector prove a paper was written by AI?
Turnitin describes its AI writing detection as a probability estimate, not proof, and instructs instructors to interpret it alongside context and human judgement [3]. That is why the report highlights individual sentences rather than issuing a verdict.
Why does my report sometimes show *% instead of a number?
When the text falls below Turnitin's confidence threshold, the report displays an asterisk instead of a precise AI percentage [3]. Short passages and heavily edited prose are the most common triggers for that low-confidence display.
Can my university see my AI score if I check my draft elsewhere?
An independent pre-submission check runs outside your institution's Turnitin account, so the report belongs to you and is not shared with your university [4]. Your institution only sees what is submitted through its own assignment.
Is the similarity percentage the same as a plagiarism ruling?
No. The Similarity Report percentage reflects matched text against comparison sources and is explicitly not a plagiarism verdict — it is a signal your instructor interprets [2].
