It is used by professionals and educational institutions across the globe to identify any potential plagiarism issues in written content. But how does Plagius compare with its competitors? In this post, we will compare Plagius Plagiarism Detector to its major competitors and take a closer look at the unique advantages and disadvantages of each tool.

Grammarly is a popular grammar and spelling checker that also includes a plagiarism checker. The plagiarism checking feature is primarily designed for students and teachers to spot plagiarism in their work. The tool is fast and reliable, and it can quickly identify any copied text from sources like websites, books, and documents. It also provides detailed feedback on any potential plagiarism issues and the original source where the content was copied from. The major disadvantage of Grammarly is that it doesn’t provide a full report of the plagiarism issues, so you may have to manually find and identify them yourself.

It has a comprehensive database of over 17 billion webpages and is able to quickly identify any duplicated content from the web. It also provides a detailed report of the plagiarism issues, including the source of the copied text.

Plagius – Interpreting Results

Plagius is a useful tool for detecting plagiarism, but it should be used in conjunction with manual review. The results of an automated system such as Plagius cannot confirm plagiarism on their own.

When interpreting the results, it’s important to pay attention to clusters of highlighted phrases in close proximity, as these may indicate plagiarism. Isolated highlighted phrases are less likely to be plagiarized.

Additionally, it’s important to keep in mind that quotes should be ignored when evaluating the results.

If plagiarism is suspected, the highlighted section should be compared to the original source for confirmation.


The percentage reported by Plagius is simply a statistical indicator of the number of sentences in the document that have been found on other websites. It should not be considered as a definitive measure of plagiarism, as the presence of a phrase on the internet does not necessarily indicate plagiarism.

For example, citations can artificially inflate the percentage of suspected plagiarism, even if they are properly referenced. Therefore, it’s important to keep in mind that the percentage of suspected plagiarism reported by Plagius should be used as a starting point for further investigation, rather than as a definitive conclusion. Additionally, it’s important to manually verify the text in question to ensure proper citation or to confirm if it is plagiarism.

Why it is a mistake to use percentage to measure plagiarism


I’ve been working with plagiarism detection for some time, and I’m often asked what percentage of plagiarism is acceptable.

My answer is quite straightforward: There is no acceptable plagiarism percentage!

I understand that a simply copied sentence, without properly mentioning the source or author, already can configure plagiarism.

Suppose a University decides that 1% suspected plagiarism, calculated by a plagiarism detector of your choice, is an acceptable index. Does it look low, right? Now imagine a 100-page work, where a whole page has been copied from the internet without the proper references. The software would probably detect 1% suspected plagiarism, but this is a full page copied – I can not imagine how this could be ignored. Obviously, this is an approximation, but it makes clear how fragile a percentage-based analysis is.

There are some programs or services of plagiarism detection slightly more sophisticated than others, but at the moment none can identify precise quotations, much less indirect quotations. Such feature would require a very advanced algorithm, certainly based on artificial intelligence.

Since no program can identify the quotations, this information will be summed to the percentage of suspected plagiarism, another factor that compromises the percentage computation.

So, what is the solution? In fact, it is still not possible to automate the whole process; a mechanical analysis, based only on percentages will be imprecise. Therefore, a manual review of the plagiarism analysis report of these tools is imperative.

Plagiarism detection programs are still great tools and, if well used, will save hours of work. That’s where I strive for the Plagius to stand out: the Plagius will not bring a magic and ready number, but it’s the tool that supports the reviewer’s work, makes it easy to check the sources, and allows the user to control what they consider relevant.

In summary: Leave the hard work for the Plagius, just take care of the review and stay in control!

First blog post

Written by the creator of the program Plagius this blog was created to publish tips, tutorials and relevant information about the Plagius program and detection of plagiarism in general.

The main purpose is to help those who need to detect plagiarism in their documents, always looking to assist with explanations focused on specific points, running away from the traditional (and boring) format of the user’s manual. 😉

Eventually posting with tips and tutorials can be updated, looking to follow the evolution of the Plagius program, thus preventing outdated information.

The first postings will be focused on answering common questions sent to the program support, in the future, posts with General issues (in the area of plagiarism) may arise..
