What Are The Differences Between Various Plagiarism Checkers?

plagiarism checker

There is a widespread misunderstanding that all the plagiarism checkers are same. Many students and writers believe that all these software work in the same way. Not all programs work the same way or scan 100% of the databases. Not all are as accurate as the most reputed ones and the reports not equivalent. If you are going to choose the best plagiarism-checking software for academic or professional tasks, you shouldn’t take things for granted. Look for a plagiarism checker that is not limited in terms of the web content and databases it can check. Choose a program like Plagramme that goes beyond and covers everything and delivers consistent results without adding your work to the database without your knowledge.

a) Different Results

Different plagiarism checker software have different sizes of databases to compare your document with, thus showing different results. There could be several reasons for this, including:

  • The underlying reason could also be that some software cannot access protected files or access all the databases.
  • When you use a FREE plagiarism checker, there is another reason why it shows a different result every time. It works by incorporating each new user document into its database without the knowledge or permission of the user. So if you get a result of 30% plagiarism the first time, another search (even with a paid account) is going to show 100% plagiarism because your document is already a part of their database. This strategy is used by most of the Free and Paid services.

On the contrary, Plagramme doesn’t incorporate user’s uploaded document to its existing database like other plagiarism checkers. However, it uses Internet along with its own database to check for plagiarism. It scans the content thoroughly to give you the desired results. It’s among a few reasons that make Plagramme a trusted choice for plagiarism detection.

An advanced program like Plagramme can conduct more sophisticated detection, including:


Paraphrase Detection: It can detect even paraphrased plagiarism. When you notice a high paraphrase score, you should review the document to eliminate all risks of plagiarism.
Detecting Bad Citations: Certain citations may be considered as plagiarism. This software can detect and inform you quality citations (in green) and bad citations (in purple) so that you can edit and correct them. It is a feature that is specific to this program because of its advanced algorithm.

b) Different Comparative Databases

Different plagiarism checkers use different comparative databases for checking your documents. This is also a reason for so much variation in the results. The last thing you want is to put your career at risk because a plagiarism checking software doesn’t compare your work with all the sources.

Thus it’s necessary to choose the plagiarism detection software that proficiently covers all available databases, beyond just the internet content, whether its journal articles, e-books, online/offline subscription content, research articles, or conference proceedings. Apart from this, make sure that it’s efficient to scan the submitted content from scientific, medical and technical publishers as well.

Only an advanced system with special agreements and partnerships is capable of accessing such extensive content databases. Plagramme scans more than 14 trillion web pages, books, articles, and periodicals to check your documents. And it relies on an accurate detection algorithm that has been developed and refined over the years. All your documents remain secure, as it uses SSL browsing technology.

c) Variable Performance for Different Languages

Most plagiarism-detecting programs have limitations when it comes to comparing content in different languages. Plagramme is unique software in that it can detect any instance of plagiarism even when your work is done in multiple languages. It is used in different countries at academic, professional and even government levels. It is used extensively by Universities and colleges from different parts of the world, including Canada, Brazil, Portugal, Hong Kong, and in hundreds of other countries where different languages are used. Additionally, it can also be used with free licenses to check papers for plagiarism and to get the scores. You will be required to pay only for the extra services you want to avail.

d) Different Levels of Consistency in Results

Have you ever wondered why a different result appears every next time you upload the same document? This is a clear sign that you should look for a reliable plagiarism checker that delivers consistent results.


Plagramme uses a multi-featured scoring system that delivers multiple reports with consistency every time you check your documents. These reports include:

Similarity Score: Each report will have similarity score that remains consistent every time you run the software.
Plagiarism-risk Score: This report will tell you the plagiarism risk in your content. A higher score means more similarities have been detected.
Paraphrase Score: This is a unique feature that tells you the number of paraphrases in the content. The higher the score, the higher the risk of plagiarism.
Matches Score: This will tell you how much of the content in your document has been found ‘matched’.


As already mentioned above, this software also delivers a bad citations score. And every time you run the check on the same document, it will return a consistent report.

So make sure to choose a plagiarism checker that addresses all the limitations in other software and helps you detect genuine plagiarism. The web and the content volume are constantly evolving and Plagramme’s algorithm is also evolving to ensure that it keeps growing with it to provide a foolproof plagiarism-detection system.
