The Crucial Importance of Checking for Plagiarism in 2023

The Crucial Importance of Checking for Plagiarism in 2023

In this age of working from home, it is all too easy to plagiarize content.

Employees working from home can visit just about any webpage and steal the content without anybody noticing. In virtual classrooms, students don’t have teachers looking over their shoulders.

The rise of artificial intelligence has only aided this, with countless AI bots popping up all over the internet ready to write content for you.

But where does this content come from? AI bots scour the internet and stitch together pre-existing original content and repurpose it to fit your needs.

These AI bots, in combination with a society that is working from home, create an environment where plagiarism is all too common. It is now more important than ever to be checking content for unoriginal work.

Below, we’ll take a close look at the various methods and tools that you can use to check for plagiarism within Google Docs itself!

How to Check Plagiarism in Google Docs in 2023

Google Docs Plagiarism Checker Add-On

One of the most convenient ways to check for plagiarism in Google Docs is with a handy plagiarism checker add-on.

Whether it’s plagiarism detection by PlagiarismCheck.org, ProWritingAid, or Plagium (more on these below), adding a plagiarism checker to your Google Doc is easy and free! Just follow these simple steps:

  • Open your Google Doc
  • Click on the ‘Extensions’ tab
  • Click ‘Add-ons’, then ‘Get add-ons
  • Now just type ‘plagiarism checker’ into the search bar

Google Workspace Marketplace

From here, you can browse available plagiarism checkers and install your preferred choice.

Once it has been installed, select a passage of text that you want to be checked for plagiarism, click the ‘Add-ons’ tab, and use your newly installed checker.

Originality Report on Google Docs

For the school environment, one of the best picks for plagiarism checking is the Originality Reports on Google Docs.

This feature is available through Google Classroom, and once enabled, allows Google Docs users to check the ‘originality score’ for their work.

Once these Originality Reports have been enabled for an assignment by the teacher, you can run up to three plagiarism checks.

If you’re a teacher wanting to turn on Originality Reports in your Google Classroom, here is what to do:

  • Access your Google Classroom account as normal
  • Click the desired class, then access ‘Classwork
  • Find the assignment you want to turn Originally Reports on for, then click ‘More’
  • In the pop-up tab, click ‘Edit’
  • Find the ‘Check Plagiarism (Originality)’ box, and click it so that it is switched to ‘On’

If you’re a student wanting to run a plagiarism check on your work with an Originality Report, here’s how:

  • Access your Google Classroom account as normal
  • Click on your class, and then ‘Classwork
  • Find your assignment, then click ‘View assignment
  • Under ‘Your work’ upload or create your file
  • If your teacher has enabled this feature, an ‘Originality Report’ section will be displayed
  • Click the ‘run’ button next to ‘Originality Report
  • Finally, click ‘View Originality Report’ to see the report

Then, you’re done!
