This is a common headache for teachers around the globe as they are constantly on the lookout to detect plagiarism and find the culprit. But, the problem with plagiarism of various types is that not all of them are easily detectable.

Some can be found easily, while others require special assistance, which is a plagiarism checker. So, how should teachers look for plagiarism? Moreover, which tools should they be using? Since finding a good plagiarism checker is a challenge, are there any good free or premium ones?

In order to answer these questions, let’s dive in and analyze a few best plagiarism checkers for teachers in 2022.

What is a Plagiarism Checker?

The idea of checking plagiarism is to find any sort of duplicate or similar content. It’s to detect similar ideas or word-to-word copying of another original content. 

Now, a plagiarism checker is a tool that scans through the internet and other databases. It analyzes the content for any sort of plagiarism or duplicity. The primary ingredients of a plagiarism checker include:

  • Natural language processing
  • Artificial intelligence 
  • Avoiding specific URLs or keywords
  • Extensive checking abilities

A plagiarism checker needs to be able to scan not only the indexed websites on the internet but also other databases that include books or manuscripts.

How to pick a plagiarism checker?

Picking a plagiarism checker isn’t rocket science, but it’s not that easy, either. As a teacher, you need to ensure the plagiarism checker you pick has a few qualities, such as:

  • The ability to scour through databases quickly
  • Efficient plagiarism detection, including elusive types such as mosaic plagiarism
  • Free or extensive word count and affordable premium plans
  • Various upload options, i.e., computer upload, Google or Microsoft One Drive import

If you are looking to find a tool, then you need to ensure they have all these qualities. Since finding a free tool is always good, make sure the premium plans aren’t unaffordable, either.
