The ACAD WRITE Plagiarism Detector

Run an automatic plagiarism check on your bachelor’s thesismaster’s thesis or dissertation – ACAD WRITE’s plagiarism detector allows you to check your thesis and academic papers for plagiarism.

It’s crucial in academia to clearly point out which ideas are your own and which ones have been taken from other sources. Even if you were very careful to mark all citations correctly, missing a mere quotation mark might be enough for your paper to be suspected of plagiarism. You can avoid this risk with a professional plagiarism check.

We use the external provider PlagScan (, used by many colleges and universities, for our plagiarism check. All data that you entrust us with for the scan will be handled in the strictest confidence and will be deleted once the plagiarism check has been completed. More information about the plagiarism checker and a guide for interpreting the results are available here.

Please contact our service agents if you have questions regarding our plagiarism detector. We are happy to help.

How to interpret the Plagiarism Report

The PlagScan report breaks its results down into three different sections, each providing specific details of the plagiarism check.

Section 1: Summary

The summary on top of the report provides an overview of the plagiarism level. This score indicates how much of the text also occurs in other sources. A result below 5 per cent is usually innocuous. PlagScan will identify three consecutive words that appear somewhere else as plagiarism. The algorithm is geared towards ignoring popular combinations of words. For example, most papers will contain standard phrases such as “this study investigates…” Most of these combinations will be ignored by PlagScan. However, coincidentally, identical combinations of words can occasionally be identified as plagiarism. A result of 0 per cent is therefore practically impossible.

Section 2: List Of References

In this section, the reports list all online sources that contain matching text passages. In some cases, the list may appear extremely long, which is not problematic per se. This is because PlagScan does not differentiate between quotes and plagiarism. It is up to the user to check if all passages copied from secondary sources have been correctly identified as quotes. Of course, certain quotes may have been copied from the original source numerous times, which is why the list of allegedly plagiarized sources can be very long. For example, R.W. Emerson’s exclamation, “To think is to act” has been quoted countless times; therefore, PlagScan will list many references if the quote occurs in the evaluated paper.

Section 3: Detail Analysis

The detailed analysis highlights all potential incidents of plagiarism in the text. This allows for manually checking whether the respective passages are plagiarism or quotes. Passages highlighted in red can be seen as problematic if they do not contain references and are not marked as quotes. Passages highlighted in green indicate direct quotes available in an online source. They will also appear if the respective passages have been correctly identified as quotes.

General Notes

It is never possible to guarantee that all text passages in a paper do not occur anywhere else. Every plagiarism software must make a preselection of the sources it scans because a full-text comparison with every available online source is practically impossible. PlagScan uses a similar method as most search engines and narrows the selections down to thematically relevant texts. Theoretically, some documents can be overlooked in this process. Also, search engines do not have a hit rate of 100 per cent. PlagScan accesses digital archives, which have been subjected to a thematic preselection. The report then contains a list of all sources analyzed. Please note that only the paper’s text will be checked for plagiarism, adopted tables and graphs will not be identified.
