Microsoft Editor runs in Word for the web to analyze your document and offer suggestions for spelling, grammar, and stylistic issues.
If you are signed in with your Microsoft 365 account, Editor also offers suggestions for refinements, like making sentences more concise, choosing simpler words, or writing with more formality.
To use Editor, on the Home tab choose Editor.
To focus on the issues you care most about, click a correction or refinement type, like Grammar or Clarity. Then, use the arrows on the suggestion card to step through each of that type of issue.
Select a suggestion to incorporate it into your document, or choose Ignore if you don't want to use the suggestion.
Note: If you change your mind about an issue you ignored, close and reopen the document, and go back to Editor. Editor will find the issue again.
Editor is running, even when the pane is closed
You might notice Editor’s red and blue underlines in your document even when the Editor pane is closed. That’s because Editor is always running in the background, checking for spelling, grammar, and some style issues.
Left-click the underlined text to see the suggestion. Use three-dot menu to:
Show or hide synonyms, to help you pick the right word for spelling errors.
Show or hide the context of the issue, in case the suggestions card is obscuring your text.
Note: In Word for the web, you can choose preferences for Editor settings by going to Review > Editor menu > Settings. These settings apply only when the Editor pane is closed.
Checking more than one language
Your document might be written in more than one language, or you might want to switch to another language for Editor to check.
To check text in another language, select the text, and go to Review > Editor menu > Set Proofing Language, and then choose your language.
Editor doesn’t check for the same issues in every language. When it’s checking more than one language, Editor lets you know which refinements are available for which languages.
Although Editor checks for grammar and refinements in more than 20 languages (and checks spelling in 89), the Editor pane is now available only in English, French, German, and Spanish. For information about the issues that Editor checks in various languages, see Editor's spelling, grammar, and refinement availability by language.
Editor in your browser
If you are running Editor as an extension in your browser while you are using Word on the web, the suggestions for your document are coming from Editor in Word, not the browser extension.
