Direct answer
Direct Answer — A pre-submission check on Turnitin means uploading your draft before the official deadline to preview its Similarity and AI writing reports. This allows you to identify unintentional plagiarism, fix improper citations, and understand how your work will be evaluated—all before your instructor sees it. While Turnitin is typically accessed through instructor-created assignments, students can use Draft Coach, resubmission-enabled assignments, or third-party services to preview their reports ahead of time [1].
Why Should You Perform a Pre-Submission Check on Turnitin?
Running a pre-submission check gives you the opportunity to catch issues before they affect your grade. When you upload a draft, Turnitin scans your text against billions of web pages, academic journals, and previously submitted papers. Any matching passages are highlighted, and you can see exactly which sources they come from. This allows you to rephrase or add proper citations, turning a potential academic integrity flag into a learning moment [2].
A pre-submission check also reduces the anxiety that often accompanies final submission. Instead of wondering whether a passage is properly cited or whether your AI-assisted editing triggered a detection flag, you see the exact score your instructor will see. With that knowledge, you can revise with purpose and submit with genuine confidence [2].
Over time, using pre-submission checks as a regular part of your writing process builds stronger academic habits. You begin to internalize the difference between effective paraphrasing and text that is too close to the original. You learn which citation practices work best for your discipline, and you develop a more intuitive sense of what constitutes original academic writing [2].
What Does a Turnitin AI and Similarity Report Show You?
The Similarity Report displays an overall percentage indicating how much of your text matches existing sources in Turnitin's databases. A color-coded scale runs from blue (no matching text) through green, yellow, orange, and red (75% or higher), giving you an immediate visual read on your originality level. Clicking the percentage opens a detailed side-by-side view where each matching passage is linked directly to its original source [3].
Beyond the overall percentage, the report lets you drill into specifics. You can filter out small matches, exclude quoted material or bibliographies, and even remove specific sources to see how your score recalculates. This level of control helps you determine whether a high similarity score is driven by properly cited quotations or genuinely problematic overlap that needs rewriting [3].
The AI Writing Report, which appears alongside the Similarity Report in many Turnitin configurations, highlights sections that may have been generated by an AI tool. Each passage is evaluated and marked with an indicator showing the likelihood of AI origin. Together, these two reports give you a complete picture: one tells you where your writing overlaps with existing sources, and the other tells you whether your prose reads as authentically human [1].
Can Students Check Their Own Turnitin Score Before Submitting?
Whether you can check your score independently depends on your institution's Turnitin setup. Many students cannot simply log in and upload a paper for preview—you typically need an instructor-created assignment to submit to. However, if your institution offers Turnitin Draft Coach, you can run Similarity Reports directly inside Google Docs or Microsoft Word, checking your work before it ever reaches an official submission inbox [4].
When Draft Coach is unavailable, resubmission-enabled assignments offer an alternative. In classic standard assignments, the first three uploads generate a Similarity Report immediately; any attempt beyond three requires a 24-hour wait. In new standard assignments, you can resubmit up to three times per 24-hour period before the system locks further uploads until the next calendar day [4].
If your assignment does not allow resubmissions at all, your first upload is final. In this case, you can ask your instructor to create a separate practice assignment for pre-submission checks. Alternatively, some students turn to independent checking services that generate Turnitin-style reports, allowing them to preview their similarity and AI scores without relying on their institution's submission portal [4].
Not every instructor enables resubmissions or Draft Coach. When you cannot get a reliable preview through your institution's system, you need a way to check your Similarity and AI scores before you hit submit. Turnitin0.com lets you upload your draft and receive a full Turnitin AI report and Similarity report—the same format your instructor uses—so you never walk into a deadline blind. The process takes minutes, and the reports are yours to review, revise against, and learn from before you ever enter the official assignment portal.

FAQ
Is running a pre-submission check through Turnitin considered cheating?
No. Performing a pre-submission check is a responsible academic practice. It demonstrates that you care about originality and proper citation. Many instructors actively encourage students to review their Similarity Reports before final submission as part of the learning process [2].
Can I check my Turnitin score more than once?
Yes, if your assignment allows resubmissions. Classic assignments let you resubmit up to three times with immediate report generation; subsequent attempts require a 24-hour wait. New standard assignments limit you to three resubmissions per 24-hour period [4].
What is a good similarity percentage before submission?
There is no universal "acceptable" percentage because expectations vary by institution, discipline, and assignment type. However, a lower percentage generally indicates less overlapping text. More important than the number itself is ensuring that any matching text is properly cited and quoted where necessary [3].
Does the AI Writing Report appear in every pre-submission check?
Not always. Whether the AI Writing Report is available depends on your instructor's Turnitin license and assignment settings. When it is enabled, you will see separate percentage indicators for similarity and AI-generated writing alongside highlighted passages in each category [1].
What if my instructor does not allow resubmissions?
If resubmissions are disabled, ask your instructor whether they can set up a practice assignment specifically for pre-submission checks. Alternatively, you can use an independent Turnitin checking service to preview your scores before submitting to the actual assignment portal [4].
