Find out exactly where your paper stands before you submit. Our plagiarism test scans 70 billion+ sources and delivers a detailed PDF report in under 15 minutes — from $0.29/page.
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. This is the figure your examiner will compare against your institution's threshold.
Direct Copies
Passages copied verbatim from another source, whether intentionally or accidentally — including material you may have taken from your own previous work.
Paraphrased Content
Text that has been reworded from a source but retains the same structure or meaning without citation. Advanced detection identifies these even when wording has been significantly changed.
Source References
Every match is traced back to its origin — the specific webpage, paper, book, or journal it came from — so you can verify whether it's a properly cited source or an oversight.
Section-Level Breakdown
See which chapters or sections of your document carry the highest similarity. Useful for prioritising your revision efforts efficiently.
AI-Generation Patterns (Combo)
With the combo test, the report also flags passages showing statistical patterns consistent with ChatGPT, Copilot, or other large language models.
Submit, wait, review. Three simple steps to a professional result.
Upload Your Document
Submit your file in PDF, Word (.docx/.doc), plain text (.txt), or OpenDocument (.odt) format. Any document length is accepted — from a short essay to a full dissertation.
PlagAware Runs the Test
PlagAware's detection engine compares your text against 70 billion+ sources. The test covers academic journals, open-access research, news articles, websites, digitised books, and student paper repositories.
Receive Your Report by Email
Within 15 minutes, you receive a comprehensive PDF report by email. It includes your similarity score, colour-coded highlights, and linked source references — everything you need to revise before submission.
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.
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.
For each flagged passage: verify whether a citation is present, add one if missing, rephrase if necessary, or confirm that the match is a standard phrase not requiring citation. Then re-test or calculate manually whether your revised score will fall within your institution's threshold.

Same Technology
Our service uses PlagAware — a detection engine actively deployed at European universities. The underlying algorithm and source database are equivalent to what many institutions use.
You Can Act on the Results
When you test your own paper first, you can revise before official submission. Once your institution runs its check, there is no opportunity to correct issues.
Your Paper Stays Private
Unlike some institutional systems, plagiarism-checker-online.net does not add your document to any database. Your paper cannot be flagged against future submissions by other students.

The largest academic and online database available for student use. Journals, books, theses, websites, Wikipedia, and student repositories — all checked in a single scan.

Even on the day before a deadline, there's time to test and revise. Results arrive in your inbox within 15 minutes — no waiting, no queues.
