Turnitin Feedback Studio is the assignment submission and feedback platform that most universities connect to their LMS, and it is where your similarity report and, when your institution enables it, your AI writing report are generated [1]. Understanding how the platform works lets you read your reports accurately, respond to instructor comments, and avoid score surprises before you hit submit. This guide explains what Feedback Studio does, how to interpret the similarity percentage, and whether you can check your Turnitin AI score before submitting.
What Does Turnitin Feedback Studio Do for Students and Instructors?
Feedback Studio is the workspace where students upload their papers through the LMS and receive automated originality and writing checks in one place. Instructors use the same screen to grade with inline comments, rubrics, and voice feedback, so submission, originality checking, and marking all happen inside a single workflow [2].
The originality check matches your text against Turnitin's large database of web pages, academic journals, and previously submitted student work, and it produces the similarity report that shows what percentage of your paper matches other sources [2]. When your institution has enabled AI detection, Feedback Studio also displays an AI writing indicator alongside the report, telling your instructor how much of the text may have been generated by AI tools.
For instructors, Feedback Studio provides the tools to act on those signals: they can open the AI writing report to review flagged sentences and discuss them with you rather than treating the indicator as an automatic verdict [2]. For students, that means the reports are a starting point for revision and conversation, not a final judgment on your academic work.
How Do You Read the Similarity Report in Feedback Studio and What Does the Percentage Mean?
The similarity percentage is the share of your paper that Turnitin matched to sources in its index, and it is shown on the report cover with a color-coded overview bar [3]. Blue indicates under 20% similarity, green 20–40%, yellow 40–60%, orange 60–80%, and red 80–100%, so the color gives you an instant sense of how much matching text is present [3].
The percentage is not a plagiarism score, and Turnitin does not decide whether your work is plagiarized; it simply flags matches for your instructor to judge in context [3]. A high percentage can come from correctly quoted material, a bibliography, or template language, while a low percentage can still hide unoriginal work that was simply reworded.
Use the Match Breakdown panel to see each matched source, and use filters and exclusions to remove quotes and bibliographies so you can see the true level of matching in your body text [3]. If matches look like accidental or unacknowledged copying, revise those sections before your instructor reviews the report.
Can You Check Your Turnitin AI Score Before Submitting Through Feedback Studio?
Whether you can see the AI writing indicator before submitting depends on how your institution has configured Feedback Studio, and Turnitin's guidance to students and instructors explains that draft-checking options vary by account [4]. In many setups, the AI writing report is generated only after you submit, which is why students often first see the score on the final report.
Turnitin's documentation recommends that students use the tools their institution provides to check drafts and understand AI indicators before a final submission, and it emphasizes that the AI report should be discussed with instructors rather than feared [4]. Because an AI score below 20% is displayed as *% rather than a single-digit number, you will typically see either 0% or the asterisk bucket on a clean draft [1].
The practical takeaway: if your institution does not give you a pre-submission view, you can still run your own check with a Turnitin-grade AI and similarity service before you upload, so you know where your paper stands [4]. Reviewing flagged sections and rewriting them before submission is the most reliable way to keep the report clean.
If you want to know exactly what your instructor will see before you submit — your similarity percentage and your AI score — turnitin0 lets you preview a real Turnitin AI and similarity report on your own draft. No guesswork and no surprises after submission: check your paper first, fix what gets flagged, and submit with confidence.

FAQ
Is the similarity percentage a plagiarism score?
No. The similarity report only shows how much of your paper matches existing sources, and it is up to your instructor to interpret the matches in context [3]. A high percentage is not an automatic accusation, and quoted or cited material can legitimately raise it.
Will I always see an AI writing indicator in Feedback Studio?
Only if your institution has enabled Turnitin's AI writing detection. The AI writing report appears alongside the similarity report when it is active, and instructors decide how to use the indicator [2].
What does the *% score in the AI writing report mean?
In the AI writing report, any score below 20% is shown as *% rather than a single-digit percentage such as 3% or 12% [1]. In practice, the only explicit low numeric outcome you typically see is 0%, so most clean drafts land in the asterisk bucket.
Can students check their AI score before submitting?
It depends on your institution's Feedback Studio settings. Some institutions only generate the AI writing report after submission, while Turnitin's guidance walks students and instructors through draft-checking options so you can understand the indicator before the final submission [4].
Does checking my paper with an AI detector before submitting affect my official report?
No. Running your own check does not change how Turnitin scores the paper you submit through Feedback Studio; the official similarity and AI reports are generated from the submitted file [4]. Use a pre-check to revise first, then submit the clean version.
