Direct answer
Submitting a paper to your university's Turnitin system without knowing what score you will receive can be a stressful gamble. A Turnitin pre submission check allows students to preview both their AI writing detection percentage and similarity score before the official submission reaches their instructor. This proactive step gives you the opportunity to identify flagged content, fix citation issues, and understand how the detection system works so you can submit with confidence. Rather than hoping for a clean report, a pre-submission check puts the data in your hands first [1].
What Is a Turnitin Pre Submission Check and How Does It Work for Students?
A Turnitin pre submission check is the process of running your draft through Turnitin's similarity and AI detection systems before the paper is submitted through your university's LMS (such as Canvas, Blackboard, or Moodle). In most institutional setups, students cannot directly submit papers to Turnitin — only instructors or administrators can trigger a check from within the learning management system [2]. This creates a gap: students often have no way to see what Turnitin will flag until after the paper is already graded.
A pre-submission check bridges this gap by allowing you to upload your document to a service that runs the paper through Turnitin's detection engines and returns both a Similarity Report (which checks against web pages, academic journals, and previously submitted papers) and an AI writing detection report (which estimates the percentage of the document that may have been generated by AI tools such as ChatGPT, Claude, or Gemini) [1]. The entire process typically takes just a few minutes, and you receive the same style of reports that instructors see on their end.
Turnitin's AI detection model breaks the document into segments of roughly five to ten sentences, overlaps those segments to preserve context, and scores each sentence between 0 (human-written) and 1 (AI-generated). The overall percentage reflects the average across all segments [1]. By checking your own paper first, you remove the uncertainty and can make informed adjustments.
What Types of Issues Can a Turnitin Pre Submission Check Detect in a Student Paper?
A Turnitin pre submission check reveals two distinct categories of issues that could affect your final grade: similarity concerns and AI writing detection flags. These are separate scores that function independently, but both carry significant weight in academic integrity reviews.
The Similarity Report detects text matches against Turnitin's vast database that includes billions of web pages, millions of published academic works, and a repository of student papers previously submitted across institutions worldwide [3]. The report highlights matched text segments and assigns an overall similarity percentage. A high similarity score may indicate insufficient paraphrasing, missing citations, or direct copying from sources — even if unintentional. The report also shows the original source for each match, so you can see exactly where your writing overlaps with existing material.
The AI writing detection report identifies segments of text that Turnitin's model predicts were generated by AI tools. This report highlights specific sentences and paragraphs in a distinct color, alongside the overall AI percentage [3]. Flags appear in the AI indicator: a green icon signals low concern, a clipped/yellow icon suggests moderate concern, and a red icon indicates a high percentage of potentially AI-generated text [1]. The AI report also now detects content that has been run through AI humanizers or paraphrasing tools, meaning simply running AI text through a rewording service is no longer a reliable bypass method [1].
Together, these two reports give you a complete picture. A paper might have low similarity yet high AI detection, or vice versa — and knowing both before your instructor runs the check is the entire value of a pre-submission scan [4].
How Can Students Perform a Turnitin Pre Submission Check Before Submitting Their Final Draft?
Since most universities restrict direct student access to Turnitin's submission portal, performing a true pre-submission check requires using a service that connects to Turnitin's detection engines on your behalf. The workflow is straightforward and takes under ten minutes.
First, prepare your document in a supported format — typically .docx, .pdf, or .txt. Undergraduate essays, research papers, reports, and even graduate theses all benefit from a pre-submission check. Upload the file to the checking service, and within 5 to 10 minutes in most cases, you will receive both the Similarity Report and the AI writing detection report [2].
When reviewing the results, start with the AI percentage displayed prominently in the report. Any score above 0% means Turnitin detected at least some segments that appear AI-generated. Next, look at the highlighted sections in the report — these show exactly which paragraphs were flagged. Cross-reference the flagged text with your actual writing to understand whether the detection relates to phrasing, structure, or patterns common in AI output [3]. On the similarity side, scan the matched sources to confirm that all quoted material is properly cited and paraphrased sections are sufficiently rewritten in your own voice.
If the report flags issues you were not expecting, you have the opportunity to revise before the paper is officially submitted. This is the core advantage of a pre-submission check: you see the same data your instructor will see, but while you still have time to fix it [4]. After making revisions, you can run the check again to confirm the scores have improved.
Running a Turnitin pre submission check through Turnitin0 gives you the exact same reports your university instructor will see, including the AI writing detection percentage, the similarity score, and highlighted flagged text — all before your paper is officially submitted. Turnitin0 processes your document through Turnitin's detection engines and returns both reports within minutes, so you can review, revise, and re-check as many times as you need.

FAQ
1. Can I run a Turnitin pre submission check more than once?
Yes. Most checking services allow you to upload, review, revise, and re-check your paper multiple times. Each run produces a fresh AI and similarity report, so you can track whether your revisions are effectively lowering the flagged percentages. This iterative process is one of the main advantages of pre-submission checks [2].
2. Will my instructor know that I did a Turnitin pre submission check?
No. When you use a third-party checking service that connects to Turnitin's detection engines, the report is delivered to you privately. Your paper is not stored in Turnitin's institutional database, nor is the instructor notified that a check was performed [1]. Only the submission made through the university's official LMS generates a record visible to your instructor.
3. What percentage on the AI detection report should concern me?
Any detectable AI percentage may raise an instructor's attention, though institutional policies vary. A score below 20% is displayed as an asterisk (*%) in Turnitin's AI writing report, meaning the detected AI content is minimal [1]. Scores above 20% will show a numeric percentage, and it is advisable to review and revise the flagged sections before submission.
4. Does a Turnitin pre submission check also detect plagiarism?
Yes. The Similarity Report that comes with a pre-submission check identifies text matches against academic journals, web content, and previously submitted student papers. This helps you catch missing citations, accidental plagiarism, or over-quoting before your instructor runs the official check [3].
5. How long does it take to get results from a Turnitin pre submission check?
In the vast majority of cases, results are delivered within 5 to 10 minutes. In rare instances, it may take up to 30 minutes. The check processes both the similarity scan and the AI detection analysis simultaneously, so you receive a complete report in a single delivery [1].
