Top Plagiarism Checkers and Tools of 2022 [Compared]

Although the rise of the Internet means we now have access to unlimited content, therefore increasing our chances of accidental plagiarism, the good news is that plagiarism checkers are here to help us. When used correctly, plagiarism checker software can help ensure that your work is original and plagiarism-free. 

In this article, we will take a look at some of the top plagiarism checkers of 2022, and how you can select the one most suitable for your needs.

The Benefits of Using Plagiarism Checkers

Besides offering you peace of mind in knowing that your work is 100% original (and alerting you when it is not), using plagiarism checkers has many advantages. Here are some of these benefits:

1. Can search a wide range of databases in no time! 

Top plagiarism checker tools are able to access a variety of databases quickly and simultaneously in order to search for content. They can take a trip around the entire web in a matter of seconds: the user simply inputs a piece of work into the plagiarism software checker, and almost instantly learns whether or not their content is original. 

2. Point users toward original texts 

With good plagiarism checkers, users are supplied with links to the original plagiarized text(s). They can then see, for example, exactly which sections were directly lifted from the source text, or which were poorly paraphrased or wrongly cited.

3. Act as an educational tool

Educators can use plagiarism checkers to teach students how to cite properly, and how to deliver original content while still demonstrating the research they have done. Moreover, such tools can eventually discourage students from intentionally plagiarizing material in the first place.

4. Suitable for various formats

Top plagiarism checkers can check content in a variety of formats, ranging from Word and excel documents to pdfs and Google docs. This means that users have the option of uploading complete files rather than just copying and pasting sections of content to check. 

5. Act as ethical guides

Plagiarism checker tools help writers remain ethical by allowing them to produce work that is authentic. Users can utilize them to ensure they are on the right track, thus protecting their own integrity and keeping themselves out of trouble.

How to Select the Best Plagiarism Checkers

The Internet hosts a wide variety of plagiarism detectors, which means it can sometimes be difficult to know how to choose the one best suited for your needs. So before we delve into our list of top plagiarism checkers, here are some key factors to consider when deciding which one is right for you.  

1. Scope 

Whether you are a high school student, an author working on your latest novel, or an educational institution, choosing a plagiarism checker will largely depend on the tool’s scope and how that corresponds to your needs. 

For instance, a student might be content with a tool that provides basic plagiarism reports, whereas an educational institution, such as a university, would probably require a more comprehensive tool with higher security features. Nevertheless, the best plagiarism checkers will have access to a large database against which your work can be checked.

2. Cost 

Some plagiarism checkers are free to use, while others either have a fixed price or are priced according to a user’s needs (word count, page count, etc.). Some plagiarism checker tools require users to pay for additional features such as more advanced plagiarism reports, or proofreading and editorial services. Deciding whether or not to pay for certain premium packages depends on the level of advancement a user requires. 

3. Compatibility

A good plagiarism checker should be compatible with different file formats (such as .doc, .pdf, .xls, etc.). Some plagiarism checkers are also able to detect various languages, which can come in handy for users working with multilingual sources. However, if a user knows they are only handling English sources and using Word documents, then there is no need for them to actively seek a plagiarism tool that caters to other languages and file formats. 

4. Accessibility 

It is useful to choose a plagiarism detector that offers a user-friendly interface. However, some plagiarism checkers can appear to be more complicated than others, especially if they host various different features. Depending on their needs, some users might sacrifice ease of access if that means they will in turn receive more advanced services.

The best plagiarism checkers should be able to accurately detect the largest possible percentage of plagiarism—and that includes uncited paraphrasing (i.e. not just straight copying of material).

Armed with this knowledge, they can then confidently examine the list of top plagiarism checkers and select that which best suits their needs.
