Microsoft Copilot can boost your writing in Word, Outlook, and OneNote — here's how

In the text entry box, you can refine the result by typing more prompts.

Although the Copilot sidebar offers more options for refining its rewritten text than it does for text it generates from scratch, it’s still underpowered compared to the Rewrite with Copilot panel. The best way to rewrite text with Copilot in Word is to use the Rewrite with Copilot panel.

Using the right-click menu in OneNote

Alternatively, in OneNote, you can right-click the top bar of a text field on a page. On the menu that opens, select Copilot and on the next menu, Rewrite.

Summarize long documents, notes, emails, or threads

You can have Copilot generate a brief summary of a long document in Word or a page in OneNote. For this to work well, Microsoft says the document or page should contain at least 300 words but no more than 20,000.

In Outlook, Copilot can summarize a long email and, even more useful, the conversation within an entire email thread.

Using the Copilot sidebar in Word and OneNote

With the document opened in Word or page opened in OneNote, highlight the text that you want summarized. (If you want a summary of the entire document or page, skip this step.)

Click the Copilot button on the Home tab of the ribbon toolbar to open the Copilot sidebar. Inside the text entry box, type summarize and click the arrow button.

Copilot will generate a summary and display it inside the sidebar.

Below the summary, there’s the familiar Copy button to copy the summary to your PC clipboard.

Below that, you can click References to see a list of citations within the document that Copilot used to generate this summary. Clicking a snippet of the cited text will show in the main window of the app where in the document or page these words are. Clicking the down arrow to the right of a citation will show the passage that Copilot used as a citation.

Summarizing emails and threads in Outlook

This summary will be posted at the top of the email or thread. Thread summaries may include citations that Copilot used in generating the summary. Clicking a citation (denoted by a number) will scroll down the thread to the cited email for you to view.

If you have Copilot with a Microsoft 365 business plan, you can use Copilot to generate a summary of a Word document when you share it with your co-workers. This summary is inserted as a passage of text inside the message that your co-workers receive inviting them to collaborate on the document.

With the document open in Word, click the Share button toward the upper right. On the Share panel that opens, click the Copilot icon inside the lower right of the “Add a message” composition box. The AI will generate and insert the summary. You can edit the summary before you send out the invite.
