Using third party content for commercial purposes is a crime. Although it can be difficult to find plagiarized content manually, there are some free online tools that allow us to locate it simply by inserting it into a text box.

Even so, you can check it with the following programs, in which you can discover it for free or with a small payment.
If you want to know if a text is copied or not, there are several ways in which we can check it. Several websites that are capable of detecting it.
