Plagiarism is taking someone else’s content and passing it off as your own. It doesn’t matter if you do it intentionally or not. Writers, college students, and researchers all need to be very careful to avoid plagiarism. You can prevent plagiarism issues by learning how to check for plagiarism in Google Docs.

Educators use various apps and add-ons to make sure their student’s work is plagiarism-free. But that doesn’t mean you can’t use someone else’s words to express an idea or a thought. You just need to know how to use citations properly. You can even paraphrase and rewrite the text, as long as you cite your sources.

    That being said, here are the best ways to check a Google Doc for plagiarized content.

    Originality Report will automatically compare your Google Docs against all books and webpages on the internet. You can run up to 5 reports on one assignment, and the document must not be bigger than 2MB. Your teacher won’t be able to see the Originality Reports you run, and you won’t be able to see the reports they run.

    Here is how to use Grammarly to check for plagiarism:

    1. Open the Google Docs document you want to check.

    2. Go to File, then Download, and choose a suitable format, typically it should be docx.
