Plagiarism Test: Run a Professional Check on Your Academic Paper
Find out exactly where your paper stands before you submit. Our plagiarism test scans about 70 billion public sources (PlagAware's figure) and delivers a detailed PDF report in about 15 minutes, from $0.29/page.
The draft discusses the relationship between evidence and interpretation. It then considers how research questions shape an argument.
Illustrative example, not an actual report or vendor interface. Highlights distinguish source excerpts, not severity. Similarity is not a plagiarism verdict.
What Gets Revealed
A plagiarism test is more than a percentage; it's a map of your document's originality. Here's what the test uncovers:
Overall Similarity Score
The headline number: the percentage of your document that matches existing published sources. It is not a plagiarism verdict or a prediction of your institution's score.
Direct Copies
Passages copied verbatim from another public source, whether intentionally or accidentally. This includes your own earlier work if it's available online.
Paraphrased Content
Text that has been reworded from a source without citation. Lightly reworded passages are often caught. Heavily rewritten text is hard for any checker, so read your matches closely.
Source References
Every match is traced back to its origin, the specific webpage or publicly available document it came from, so you can verify whether it's a properly cited source or an oversight.
Highlighted Passages
Matching passages are highlighted in your text, each linked to its source. Highlight colors only tell the sources apart, so review each match yourself.
AI-Generation Patterns (Combo)
With the combo test, the report also measures AI-typical phrasing. The 0 to 100 score, with 50 neutral, is not an authorship probability and cannot identify a model.
How the Plagiarism Test Works
Submit, wait, review. Three simple steps to a professional result.
Upload Your Document
Submit your file in PDF, Word (.docx/.doc), or plain text (.txt) format, up to 50 MB. Use a text-based file with selectable text.
PlagAware Runs the Test
PlagAware's detection engine compares your text against about 70 billion publicly available texts, according to PlagAware. The test covers websites, news articles, open-access research, and freely available documents. It has no access to paywalled or subscription journals, and your document isn't added to a plagiarism pool.
Receive Your Report by Email
In about 15 minutes, you receive a comprehensive PDF report by email. It includes your similarity score, highlighted matches, and linked source references, everything you need to revise before submission.
How to Interpret Your Test Results
A high similarity score doesn't automatically mean you've plagiarised. Understanding what the number means, and what to do about it, is the key to using your test result effectively.
What the score includes
The similarity score counts all text that matches existing sources, including properly cited quotations, standard phrases, and methodology descriptions common to your field. Not all matches are problems.
What to look for in the report
- Large single-source matches: A high match against one specific source is a stronger warning sign than many small matches across different sources.
- Uncited matches: Borrowed ideas need attribution. Mark copied wording as a quotation and cite it, or write a genuine paraphrase with a citation.
- Self-plagiarism: Reusing your own earlier work without disclosure is flagged like any other match, but only if that work is publicly available online.
What to do next
For each flagged passage: verify attribution and quotation formatting, write a genuine paraphrase with a citation where appropriate, or confirm that the match is a standard phrase not requiring citation. Inspect each revised passage against its source. A lower score alone does not establish correct attribution or guarantee acceptance.

Our Test vs. Your University's Check
A check before you submit helps you fix problems early, though no outside tool reproduces your university's exact number.
Built for Pre-Checks
Our service uses PlagAware, which offers licenses for universities and schools. We offer it as a pay-per-scan pre-check for individual students. Your institution's own tool may search different sources, so treat our report as a way to find gaps early, not as a prediction of its result.
You Can Act on the Results
When you test your own paper first, you can revise before official submission. Whether you can revise after official submission depends on your institution's procedure.
Your Paper Stays Private
Your upload is not added to a plagiarism pool. PlagAware deletes the scan text after report creation. Separately, our upload download tokens expire after 48 hours, and expired files are cleaned up opportunistically. We do not promise physical deletion at the instant a token expires. Publicly available copies of your work can still be matched.

Plagiarism Test: FAQ
A plagiarism test compares your document against publicly available sources, about 70 billion texts according to PlagAware, such as websites and open-access publications, to identify passages that match existing content. It flags copied passages and many lightly reworded ones with a percentage similarity score and source references. It can't see paywalled or subscription journals.
