Similar to Google Scholar, Google Books is a useful tool for checking for plagiarism in written works, particularly books and published materials. You can search for unique phrases or sentences within the vast database of books available on the platform to detect any instances of plagiarism.

  1. Cross-check citations and references

Ensure that all the citations and references in your work are accurate and correctly attributed. Cross-check your work against the original sources to confirm that you have given proper credit to the authors and their ideas.

  1. Use free browser extensions

There are several free browser extensions available that can help you detect plagiarism as you write or edit your content. Examples of these extensions include:
