The number of online sources with free access has increased dramatically, and the rate in which they increase is only accelerating. That is why more and more people bow to the temptation to pass off someone else’s writing as their own. Once you start copy-pasting, it’s hard to get rid of the habit. But what if one day you are caught plagiarizing?
If you are a student, you should be aware of the serious consequences plagiarism brings. Low grades, re-submission of papers, or, even worse, suspension or expulsion from school. For writers or bloggers to be found guilty of plagiarism is not less risky, since they can lose high website rankings and ruin their reputations and their careers.
To keep from getting into trouble, you should use plagiarism detection tools. Here is a brief guide for seven plagiarism checkers that can help you avoid getting takedown notices and protect yourself from accidental plagiarism.
1. Unplag
This plagiarism detection tool is especially recommended to students, educators, writers and editors. With Unplag, you don’t need to install any extra equipment and programs to use the checker, as it operates online.

In order to identify even the smallest plagiarized passage, it checks your text against 16 billion pages and documents on Google and Bing. Unplag provides a plagiarism report after each scan is over.
