Why Check for Plagiarism in Google Docs?

Before diving into checking for plagiarism, it’s essential to understand why this is an important step in your work. Here are some reasons:

Ease of use

Checking for plagiarism in Google Docs is straightforward and user-friendly. By leveraging a plagiarism add-on, you can quickly scan your entire document without leaving the platform.


Unlike Microsoft Word, which requires downloading additional software to check plagiarism, Google Docs integrates with various plagiarism checkers via the extensions menu. This makes it an ideal tool for educators wanting to verify the originality of their students’ work quickly.

Comprehensive Reporting

A major advantage of using plagiarism add-ons in Google Docs is the ability to generate a full report. This gives detailed insights into the uniqueness of your writing and can be helpful when you’re creating a document or course.

Real-time checking

As you write or create content within Google Docs, the plagiarism checker scans your work simultaneously. This real-time feedback allows you to make immediate corrections and ensure the originality of your work.


The menu bar in Google Docs makes all functions, including the plagiarism checker, easily reachable. This accessibility fosters a more efficient writing process, especially for extensive documents.

Tips for Avoiding Plagiarism

While the tools and methods mentioned above – including plagiarism checker add-ons, Google’s Originality Check, and external anti-plagiarism websites – can effectively detect plagiarism in Google Docs, avoiding plagiarism should be the ultimate goal.

Here are some tips to help maintain your academic integrity:

Understand what constitutes plagiarism

Plagiarism isn’t just copying and pasting someone else’s work. It also includes paraphrasing without giving proper credit, using someone else’s ideas as your own, or reusing previous work (self-plagiarism).

Learn to cite correctly

Always give credit where credit is due. Use the appropriate citation style for your discipline and ensure you know how to cite in the body of your document and in the bibliography or reference list.

Use your own original words

Strive to express your understanding of the topic in your own words. This not only prevents plagiarism but also helps you to better understand and remember the material.

Use a plagiarism checker

Before submitting your work, use a plagiarism checker to scan your document. This allows you to spot any accidental plagiarism and rectify it before submission.

Make use of Google Docs’ features and add-ons

Utilize Google Doc’s built-in tools and add-ons to help you avoid plagiarism. Use the “Originality Check” feature or install a reputable plagiarism checker add-on from the add-ons menu.

Understand the limitations of plagiarism checkers

Keep in mind that no tool is perfect, and plagiarism checkers can sometimes miss instances of plagiarism or flag non-plagiarized content as copied. Always review the report carefully and cross-verify with a Google search or another tool if needed.

Final Thoughts

In conclusion, successfully checking for plagiarism in Google Docs involves a combination of diligence, the right tools, and understanding. Always strive to maintain academic integrity by using original words, giving proper citations, and understanding what constitutes plagiarism.

With these tools and guidelines at your disposal, ensuring your Google Docs are free from plagiarism becomes easier and more effective. It is always better to prevent plagiarism than to deal with its consequences. So continue to make good use of these tools and strategies, and foster a culture of respect for original work.
