Checking the similarity of your essay before you submit is one of the smartest habits you can build, because the score your professor sees is generated the moment Turnitin runs your paper through its comparison engine [1]. Turnitin matches your writing against a vast database of web pages, academic publications, and previously submitted student papers, then returns a similarity percentage that highlights every matching passage [1]. That means the report you can generate now is the same kind of evidence your instructor will review later, so a pre-submission check turns an anxious submission into a confident one.
How Can I Check The Similarity Of My Essay Before Submitting It To Turnitin?
The most reliable way to check similarity is to run your finished essay through Turnitin itself, because only Turnitin's engine produces the exact percentage your instructor sees [2]. When you submit to an assignment that has the similarity report enabled, Turnitin scans the document against the sources in its databases and generates a report, usually within minutes. Whether you can view that report before the deadline is decided by your instructor's assignment settings, so access varies from course to course [1].
Turnitin's similarity workflow is built on the same databases that power institutional checks: internet content, scholarly journals, and the student paper repository [2]. This is why a generic plagiarism checker can show 0% while Turnitin flags a passage — the underlying repositories are not identical. For the most accurate preview, you want a check that uses Turnitin's own engine and its standard settings.
A practical tip is to check your essay only after it is complete and formatted, because Turnitin compares the submitted file as-is, including headings and references. Run the check, read every flagged source, and rewrite any passage that appears in another source before your final submission [2]. Checking early and checking again after edits reduces the risk of submitting an essay that looks copied even when it was written honestly.
What Does A Turnitin Similarity Report Show And What Is A Good Similarity Score?
A Turnitin similarity report shows a color-coded percentage and a side-by-side breakdown of every match, with the original source displayed next to your text [3]. The percentage reflects how much of your essay matches indexed content, while the report flags individual sentences and passages for closer review. Exclusion settings — such as removing quotes and the bibliography — can change the final number, so the same essay can show different scores depending on how the check is configured [3].
There is no universal "good" score, because the acceptable range depends on the assignment type, the discipline, and your instructor's expectations. A mathematics paper may legitimately sit lower than a literature review that quotes many sources. As a rule of thumb, most institutions treat scores below 15–25% as low risk, but the quality of the matches matters far more than the number itself [3].
Instead of chasing a single target number, read what the report actually tells you. Large blocks of identical text from one source are a red flag, while short, properly cited matches are normal academic practice. If your report highlights material you did not intend to copy, that is exactly what the pre-submission check is for — revise and re-check before your professor does [2].
How Can I Get An Official Turnitin Similarity Report For My Draft Before I Submit It?
Students often discover that their university only lets them see the similarity report after the first submission, which makes a genuine pre-submission check impossible through the usual workflow [4]. Whether students can check before submitting depends entirely on how the institution configures Turnitin, and many programs leave that option off. That is why a growing number of students use a service that mirrors the official Turnitin check before they ever upload the final draft [4].
The key is to use a real Turnitin report, not an imitation. Services such as turnitin0.com run your file through Turnitin's actual similarity and AI detection engines and return the same report format professors see — score, flags, and match highlights. With a genuine report in hand, you can decide whether to revise, rephrase, or cite properly before the official submission window closes.
Aim to run your check at the final drafting stage, after formatting is complete, and leave yourself time to act on the results. If the report comes back clean, submit with confidence; if it flags passages, address them and run a second check to confirm the fix [4]. This workflow turns the similarity report from a post-submission verdict into a preparation tool.
Seeing your own official Turnitin similarity report before your professor does is the difference between a nervous submission and a confident one. turnitin0 makes that possible: upload your essay and get the exact same AI and similarity reports your instructor would see, so you can fix flagged text and lower your score before it counts. Your real report, ready in minutes — no waiting on your university's settings.

FAQ
Is a 20% similarity score considered good?
For most university essays, a score under 20% is considered low risk, but there is no universal threshold because expectations vary by assignment and instructor. What matters more is whether the matches are properly cited and whether large passages come from a single source [3]. Always read the report rather than relying on the number alone.
Does Turnitin check my essay against other students' papers?
Yes, Turnitin compares your essay against its student paper repository, which contains previously submitted work from institutions worldwide [1]. That is why an essay can be flagged for matching a paper you have never seen. Instructors control which repositories are included in each assignment [2].
Can I check my essay's similarity before my professor does?
Whether you can see the report before the deadline depends on your instructor's assignment settings, and many courses restrict pre-submission access [4]. If your course does not allow it, you can use a service like turnitin0 to run the official Turnitin check on your own draft first.
What is the difference between a similarity score and an AI score?
The similarity score measures how much of your text matches other published or submitted sources, while the AI writing score estimates how much of the text was generated by AI tools. Both appear in the instructor's report, and both are worth checking before submission [1]. Turnitin0 delivers both reports from the same engine.
How long does a Turnitin similarity report take to generate?
Institutional reports typically generate within a few minutes of submission, and most checks complete in roughly 5–10 minutes [1]. That means you can check your draft, revise the flagged sections, and run a confirmation check without waiting days.
