Want to make sure your work is truly yours? The similarity checker in Word highlights what's unique in your document and makes it easier to add citations. You can focus on your writing, knowing that your original ideas stand out and your sources are properly credited.

  1. On the Home tab, choose Editor.

  2. On the Home tab, select Editor. In the Editor pane that appears, scroll down to Similarity and select Check for similarity.

    When the check is complete, Editor shows you how much of your content matches text that it found online (indicated as a percent), and the number of distinct passages in the document for you to review.

  3. If Editor finds similarities, click or tap Similarities reviewed. In each section, you'll have the option to insert a citation. A link to the original content can help you decide if you should add a citation. If you feel a citation isn't necessary, select Ignore.

When Editor reviews a passage, it's underlined with a dotted line. To revisit a source or add a citation, click the passage.

Inserting citations

Inserting a citation adds it right after the text, with quotation marks added by Editor, as needed. Remove any marks you don’t need.

For bibliographies or works cited, use Copy full citation to paste into your document.
