Example of plagiarism detection

Our scoring system offers several features to help make your document the absolute best it can be. With all of these features, as well as color-coding to alert you to any problems, you’ll be able to quickly edit and correct your document with ease.

Similarity score

All reports are provided with a similarity score. This score shows how many similarities are in your documents.

Plagiarism risk score

This score shows you the risk of plagiarism in your document. The more similarities that are detected, the bigger the risk of plagiarism. Our research has shown that this feature detects the risk of plagiarism by 94%. This is but one of many reasons why users love our system.


This score alerts you to the number of paraphrases in your document. A high paraphrase score may signal plagiarism. Be aware of the high paraphrasing score.

Improper citations

This score shows how many improper citations there are in your document. While it’s acceptable to use citations, they should not comprise the majority of your document. It’s also wise to verify the source of any citations used, in order to avoid the risk of plagiarism.


This score shows the amount of “matched” parts in your document.

Example of highlight plagiarism

If any kind of plagiarism is found in your document, the data is highlighted for your review and correction. Our plagiarism checker system offers certain features to help you edit and correct your document – note, that good quotations will be highlighted in green, paraphrases in orange, and improper quotations in purple.

Our plagiarism checker will put links to the sources on the matched parts in your document. These links allow correct any improper quotations, words, and paraphrases in your document. If you are confident that the quotations are placed properly in your document, a simple verification on your part will allow you to proceed with your document review and download.

Plagiarism checker sources and matches

Some citations may be recognized as plagiarism by teachers so it is important to check the paper for correct citation in order to avoid any unpleasant consequences. Our plagiarism checker will let you know which citations are good – they will be marked green. It will also mark purple all the citations which are recognizable as plagiarism, so you will know what citations you should edit. This is the unique plagramme feature – no other plagiarism detection system offers such a feature.

Our system’s enhanced technology detects not only copy & paste plagiarism, but also paraphrased plagiarism. If you receive a high paraphrase score, it’s important to carefully and thoroughly review your document to avoid the risk of plagiarism.

Plagiarism checker citations

Even if your document is written in several different languages, our multilingual system is capable of detecting plagiarism. That’s why our plagiarism checker system is recognized as the national plagiarism detection system in several different countries.
