Table of contents

Checking for plagiarism is an important step to ensure that the content of your article is original. There are many different ways to do this for free on the Internet. In this article we will show you the 10 best tools for a plagiarism check and also explain how to avoid plagiarism.

It is often not so easy to find out whether you have plagiarized something or not. Because the rules for citing can be very confusing, most of the time you won’t even know what you are still allowed to do and what not. That’s why you should still use a service that offers professional plagiarism checking, even if you have already checked your work for plagiarism yourself. This is the only way you can be sure that your work is actually free of plagiarism! Unfortunately, many plagiarism checks are not for free. However, we will show you what options you have to perform a plagiarism check free online.

Why is a plagiarism check important?

A professional plagiarism check is important because it can help you put your work to the test and see if you have actually created something new and original. If you simply copy someone else’s work, you probably won’t be able to receive credit for your work and rank high on search engines. A plagiarism check can also help you avoid being penalized for your work. 

For online content, this can help protect copyright. When an author publishes an article or other online content, they want to make sure that their content is not copied by someone else and passed off as their own. A plagiarism checker can help prevent this from happening. For a scientific paper, a plagiarism check is also relevant, as plagiarism can lead to the paper being rejected or the author being penalized.

A plagiarism scanner is a useful tool to check your own content or the content of others for plagiarism. There are many different plagiarism scanners that you can use for an online plagiarism check. As already mentioned, many of these scanners are unfortunately not cheap and have to be paid for, which is why we want to introduce you to free alternatives in this article. If you would like to get a more detailed insight into what a plagiarism scanner can do and how it works, you can have a look here. Otherwise, we have created a list of free online plagiarism checkers for you:
