Direct answer
An article plagiarism check compares your draft against published papers, web pages, and other student submissions, then returns a similarity report that shows exactly which passages matched and where they came from. Turnitin's Similarity Report is the version most universities use, and it highlights matches by source type rather than issuing a verdict on your work [1]. That distinction matters: the report is diagnostic evidence you read and act on, not a score that decides your grade by itself [1]. For students finishing an article, essay, or dissertation chapter, running a check before the deadline is the cheapest way to catch a missing citation while you can still fix it.

An article plagiarism check compares your draft against published papers, web pages, and other student submissions, then returns a similarity report that shows exactly which passages matched and where they came from. Turnitin's Similarity Report is the version most universities use, and it highlights matches by source type rather than issuing a verdict on your work [1]. That distinction matters: the report is diagnostic evidence you read and act on, not a score that decides your grade by itself [1]. For students finishing an article, essay, or dissertation chapter, running a check before the deadline is the cheapest way to catch a missing citation while you can still fix it.
How Do I Run a Plagiarism Check on My Article Before Submitting It?
In most institutions, you cannot simply log into Turnitin and check your own draft — your instructor creates the assignment, sets the repository options, and controls whether students can view or resubmit the report [2]. That is why many students use an independent pre-submission check: you upload your .docx, .pdf, or .txt file, and you get back the same two reports your professor would see — a similarity report and an AI writing report — without touching your official submission slot [2].
The practical workflow is short. Finish your draft, remove any tracked changes, confirm your references are formatted, then upload the file for checking. When the report arrives, read it in order: start with the overall similarity score, then open each highlighted match and ask whether the passage is properly quoted and cited [2]. Turnitin's own guidance recommends exactly this review step, because the report is designed to surface missing quotation marks, over-long paraphrases, and citation errors before they reach a marker [2].
Turnitin also lets you exclude quotes, bibliography, and small matches so the remaining number reflects the prose you actually need to rewrite [2]. If a match points to a source you genuinely used, the fix is usually a citation, not a rewrite; if it points to something you never read, the fix is to rephrase the idea in your own words [2]. Either way, you are editing with evidence rather than guessing.
What Does the Similarity Score in a Plagiarism Report Actually Mean?
The similarity score is the percentage of your submission's text that matched sources in the comparison database — it is a measure of textual overlap, not a plagiarism percentage, and it is not a judgment about intent [3]. Turnitin explicitly states that it does not set a "safe" similarity percentage, because no universal threshold exists; a low score does not guarantee originality, and a high score does not prove misconduct [3].
Context decides everything. A 20% score can be entirely legitimate if the matched text is quoted material with correct citations, a common phrase, or a reference list that a reviewer chose not to exclude [3]. Conversely, a 6% score can contain a single copied paragraph that matters far more than the number suggests. Reviewers are trained to look at source type, match length, and whether the passage is attributed, not at the headline figure alone [3].
This is why a plagiarism report is best read source by source. Open each match, check the highlighted span, and confirm the citation is present and accurate [3]. Once you have done that, the score becomes a checklist of specific edits rather than an anxiety-inducing statistic — and you will know precisely which sentences to revise before you submit.
Is It Safe to Check My Article With a Third-Party Plagiarism Checker?
Safety comes down to one question: does the check add your file to a student paper repository? Whether a submission is stored depends on the repository setting the instructor chose for the assignment, and stored drafts can later match your own final submission and inflate your similarity score [4]. A non-repository check avoids that trap entirely — the file is not added to the student paper database, and the resulting reports are not shared with third-party databases [4].
Before uploading anything, read the service's data policy and look for three things: non-repository checking, a clear statement that reports stay private, and the ability to delete your file from your account afterwards [4]. If a checker cannot tell you where your document goes, treat that as a no. Privacy hygiene matters more than saving a few minutes, especially for unpublished research or coursework you have not yet submitted [4].
It also helps to check the same draft more than once if you make substantial edits after a report. Because a repository-stored draft can create a self-match later, students who plan to check early and often should prefer a non-repository service so their own earlier version never becomes a source in their own report [4]. Used that way, a pre-submission plagiarism check is a low-risk, high-information step in your writing process.
If you want the same similarity and AI writing reports your professor sees — before your official submission slot is used up — turnitin0 gives you that preview in minutes, with non-repository checking and downloadable PDFs you can keep.

FAQ
Does a high similarity score mean I plagiarized?
No. The similarity score measures textual overlap with sources in the database, and Turnitin states it is not a plagiarism percentage [3]. A high score often reflects correctly quoted material, common phrasing, or a reference list that was not excluded [3].
Can I check my article in Turnitin before I submit it?
Usually not through your institution's account, because your instructor creates the assignment and controls repository and viewing settings [2]. Independent pre-submission checks exist precisely to fill that gap, returning the same report types your professor would see [2].
What similarity percentage is safe to submit?
There is no universal safe threshold — Turnitin does not publish one, and a low score does not guarantee originality [3]. Read the report match by match and confirm every highlighted passage is properly quoted or cited [3].
Will checking my draft get stored in the student paper database?
It depends on the repository setting used for the check. Non-repository checks do not add your file to Turnitin's student paper database and do not share reports with third-party databases [4].
Can my own earlier draft show up as a match?
Yes, if the earlier version was stored in a repository. Stored submissions can later match your own final file and raise your similarity score, which is why non-repository checking is preferable for drafts [4].
