Direct answer
You can check your own document for plagiarism by running it through a similarity checker before you submit, and the two realistic routes are an instructor-enabled Turnitin draft folder or an independent pre-submission check that returns the same style of similarity report [1]. Turnitin's own student guidance confirms that self-checking depends on whether your institution has switched the option on, so many students never get access through their university account [2]. A similarity score is a match percentage, not a plagiarism verdict, so the useful output is the highlighted report rather than the headline number [3]. If your school has not enabled a draft submission, you can still obtain a real Turnitin-style similarity report on your draft from an independent service such as turnitin0 [4].
Can I check my own document for plagiarism before I submit it?
Yes, but only through routes that are actually open to you, and that is where most students get stuck. Turnitin's student quickstart lists two self-check paths: a draft assignment created by your instructor, or the standalone self-check tool where your institution has enabled it [1]. If neither exists in your account, you have no way to generate a report from inside the university system, no matter how early you start.
The reason is structural rather than technical. Turnitin's similarity checking is licensed to institutions, and the student-facing submission options are configured by the instructor or administrator, not by the student [2]. That is also why the repository setting matters: a paper submitted to the standard student paper database stays there, so if you later submit the same work to the real assignment it can match itself and inflate the score [2].
The practical consequence is that "check my document" splits into two different questions. One is can I access a checker at all, and the other is will the check contaminate my later submission. A non-repository check answers both, because the file is compared against the databases and then discarded rather than retained [2]. Ask which mode you are using before you upload anything, because the answer changes what the score means.
How do I read a Turnitin similarity report once I have it?
Start by treating the percentage as a measurement, not a judgement. Turnitin's interpretation guide is explicit that the similarity score reflects the proportion of your document's text that matches sources in the comparison databases, and it does not by itself indicate plagiarism [3]. A paper with heavy but correctly cited quotation can legitimately score high, while a paper with unattributed paraphrase can score lower and still be a serious problem.
The Match Overview is where the real information sits. It lists sources in descending order of how much text they match, so the top entry tells you where to look first, and clicking a source shows the exact highlighted passages [3]. Read the highlights rather than the number, and check each one against your citation practice — a missing quotation mark or a paraphrase that stayed too close to the original is the usual culprit.
Remember that the displayed figure is configurable. Instructors can exclude quoted material, the bibliography, and matches below a set length, which means the score you see in one context may not be the score recorded in another [3]. If your report shows a high percentage, look at what is being counted before you panic or, worse, before you start rewriting text that was already properly attributed.
How do I get a real Turnitin similarity report on my draft before the deadline?
Turnitin's originality checking works by comparing a submission against its internet, publication, and student paper databases and returning a report with highlighted matches and a source-type breakdown [4]. That comparison is the valuable part, because it tells you whether your overlap comes from web pages, journal articles, or other students' papers — three problems with three different fixes [4]. The obstacle is access: institutional licensing normally gates the check, which is exactly why students without an enabled draft folder search for another way in.
An independent pre-submission check closes that gap. You upload your .docx, .pdf, or .txt file, the document is compared without being added to Turnitin's student paper database, and you receive a downloadable similarity report alongside an AI detection report. Because the file is not retained in the repository, submitting the same work to your real assignment afterwards will not trigger a self-match, which is the failure mode that catches students who use a university draft folder carelessly [2].
For a document under 30,000 words, turnaround is typically under 15 minutes, so a check can realistically fit inside a final editing session rather than forcing you to plan days ahead. The report you get is the same style of artifact your instructor sees, including the match highlights and source list, so you can act on it directly: fix the unattributed paraphrase, add the missing quotation marks, and re-check if the overlap was substantial [3]. Reading the report is the skill; getting one on demand is what makes the skill usable.
If your university never switched on a draft folder, you are not out of options — you just need a checker that returns the report your instructor will actually see, without adding your file to the database you are about to submit into. turnitin0 was built for exactly that pre-submission moment: upload your draft, get the similarity and AI reports in minutes, and fix the highlighted matches while you still have time to fix them.

FAQ
Does a high similarity score mean I plagiarised?
No. The score is the share of your text that matches sources in the comparison databases, and Turnitin's own guidance separates that measurement from any plagiarism judgement [3]. Read the highlighted matches to see whether the overlap is cited quotation, common phrasing, or genuinely unattributed text.
Will checking my document add it to Turnitin's student paper database?
That depends entirely on the mode used. Standard repository submissions are retained and can later match your own work, while non-repository checks compare the file and do not keep it [2]. Confirm the setting before you upload, especially if you plan to submit the same document to your real assignment.
Why can't I find a self-check option in my Turnitin account?
Because the option is institution-controlled. Students can only self-check where the university has enabled it; otherwise an instructor has to create a draft assignment first [1]. If neither is present, an independent pre-submission check is the practical alternative.
What file types can I check?
Turnitin accepts common document formats such as.doc,.docx,.pdf,.txt, and.rtf [1]. An independent check typically asks for .docx, .pdf, or .txt, so export your draft accordingly before uploading.
How long does a pre-submission check take?
For a typical essay or dissertation chapter, an independent check usually returns within 15 minutes, which is short enough to fit into a final proofreading session. Plan for a re-check if your first report shows substantial overlap you need to rewrite [4].
