What is anti-plagiarism software

These tools, which are usually online, allow a text to be reviewed to check its originality and avoid plagiarism of other existing ones. An anti-plagiarism software compares in a few seconds the text that we select with millions of other texts published on the Internet to find matches.


Some of these tools are so precise that in addition to finding exact matches of entire passages, they can also identify word fragments from other texts indicating whether plagiarism exists.

Reasons to use an anti-plagiarism program

Plagiarism is a very common practice and it has become even easier to do with the arrival of the Internet and new technologies, but we must not forget that plagiarism devalues ​​the work and effort of another person when creating anything, not just texts.

These are the reasons why anti-plagiarism programs are frequently used:

  • For ethical reasons . As we mentioned before, the creation of a text requires time, effort and a person, not only in writing it, but in all the previous work of documentation and data verification. Plagiarism of an original text is a way of underestimating this effort, either due to lack of time or inexperience.
  • For credibility . When we provide data or make assessments based on real and verified information, we create texts in which people seek support or form an opinion trusting the experience of an expert. Practicing plagiarism will lose all credibility and may even lead to the closure of our website. 
  • By SEO . Google looks very closely at the content between some websites and others to penalize those that practice plagiarism when creating their content. The most common consequences are that Google will prevent your website from appearing in the first positions in searches, that the plagiarized content will be directly eliminated and that the keywords of your website will be seriously affected.
  • For profitability . In order to achieve economic profitability with a website that is not exclusively dedicated to the sale of services or products, it is vitally important to create completely unique and original content that users consider very relevant. Therefore, if we opt for plagiarism techniques, we will risk suffering the consequences imparted by Google that we mentioned earlier, as well as damaging our image.

What types of plagiarism exist

Plagiarism not only affects entire paragraphs of a text, but can manifest itself in multiple ways:

  • Cloning . These types of texts are usually delivered as an exact copy of another existing text with a 99% match. Some of these texts can be recognized by a characteristic shading that appears by preserving the formatting of the original text.
  • Copy and paste . This type of plagiarism is very similar to cloning, with the difference that only specific fragments of the text are copied and then literally pasted into another. They do not have to assume a high percentage of coincidence.
  • Replacement . These texts are characterized in that the content is the same as the original text, but with some changed words and expressions.
  • Mosaic . These texts are literally fragments of different sources making them fit and have coherence, without using references or citations.

Creating original content today can be quite a challenge, especially if we talk about specific topics that require specific training or experience.

It is important to be aware of how widespread the plagiarism technique is to create content, especially on the Internet, without the need to know a subject or have experience. However, it is a serious lack of respect for the people who work, train and inform themselves to create original and quality texts, in addition to being able to see the credibility of a web page or individual greatly affected if it is discovered that they plagiarize other sources.
