Direct answer
Turnitin is the originality and AI writing detection platform most universities run behind their assignment submission points. When you submit a paper, it produces two reports: a Similarity Report that matches your text against a large database of academic work, websites, and publications, and an AI writing report that estimates how much of your text was likely generated by AI tools [1]. Knowing what those reports show — and how to read your own results — is what separates students who submit prepared from students who submit blind.
Introduction
Turnitin is the originality and AI writing detection platform most universities run behind their assignment submission points. When you submit a paper, it produces two reports: a Similarity Report that matches your text against a large database of academic work, websites, and publications, and an AI writing report that estimates how much of your text was likely generated by AI tools [1]. Knowing what those reports show — and how to read your own results — is what separates students who submit prepared from students who submit blind.
What Does Turnitin Check in a Student's Paper and What Do the Reports Show?
Every submission is run through two independent checks. The similarity engine scans your paper against scholarly articles, student papers, and web content, then produces a color-coded Similarity Report that highlights matched passages and shows an overall percentage [2].
The second check is the AI writing report, which analyzes the text for patterns typical of ChatGPT, Claude, and other large language models. The report returns an overall percentage and highlights the sentences it believes were machine-generated, with per-sentence flags you can review line by line [2].
Neither score is a verdict on your integrity. Turnitin positions both reports as starting points for discussion — instructors decide how to interpret the numbers in the context of the assignment, your writing history, and your institution's policy.
One detail matters for students: in the AI writing report, any score below 20% is displayed as *%, not as a precise low number, so you should not expect to see a "3%" or "12%" figure in most cases. Only 0% appears as an explicit numeric low outcome.
Can Students Run a Turnitin Check on Their Draft Before the Final Submission?
In most institutions, students cannot log into Turnitin and check a paper whenever they want. Access is tied to your course's assignment submission point, and reports are typically generated after you submit — which is why many students never see their score until it is too late to change anything [3].
Some instructors enable multiple attempts or a draft mode, which lets you submit, read the report, revise, and resubmit before the due date. This is entirely at the instructor's discretion and varies from course to course, so the first step is checking your assignment settings [3].
A small number of universities run a separate self-check or similarity preview service for students. If yours does not, the practical alternative is an independent Turnitin check on your draft before you submit anything to your course.
How Can Students Get a Real Turnitin AI and Similarity Report on Their Draft Before Submitting?
The most reliable way to know what your instructor will see is to run your draft through the same engine that powers institutional checks — Turnitin itself — before submission. Academic integrity guidance consistently recommends that students review their own originality and AI indicators in advance rather than discovering flags after the fact [4].
A real pre-submission report gives you three numbers to read together: the similarity percentage, the AI writing percentage (or the *% bucket), and the location of flagged sentences. That combination tells you exactly which passages to revise, paraphrase, or rewrite before the final submission [4].
Once you know where the flags are, you can act: fix citation errors, rephrase borrowed text in your own voice, or humanize AI-generated sections so your final draft reflects your own work. Checking first turns a surprise score into a managed outcome.
Reading about reports is one thing; seeing your own is another. turnitin0 lets students run their draft through the real Turnitin AI and similarity engine before submitting, so you know exactly what your instructor will see — score, flags, and matched sources — while there is still time to act.

FAQ
Can students see the same Turnitin report their instructor sees?
Yes — a genuine Turnitin check produces the same Similarity and AI writing reports instructors access through their institutional system, which is why independent pre-submission checks mirror the official experience [1][2].
What does *% mean in a Turnitin AI report?
Any AI writing score below 20% is shown as % rather than a single-digit number, so a % result means your text is below the flagging threshold; 0% is the only explicit low numeric score you will typically see [2].
Can I check my paper with Turnitin before submitting it to my course?
Only if your instructor enables draft or resubmission modes. Otherwise, students can run an independent Turnitin check on their own draft before the final submission [3].
What should I do if my Turnitin AI score is high?
Start by reviewing the flagged sentences, then rewrite or humanize those sections in your own voice and re-check the draft before submitting [4].
Does checking my paper on turnitin0 put my work into a public database?
No — submitted papers are never archived and never sent to third-party databases, so your draft stays private.
