How to Use Copilot in Word
Last updated: July 19, 2026
Quick answer
Copilot in Word does three jobs: Draft with Copilot writes a document from a plain-language brief (optionally grounded in your existing files), the margin Copilot icon rewrites or tightens any selected text, and the chat pane summarizes and answers questions about the open document with citations. You need Microsoft 365 Copilot (~$41 CAD/user/mo, business) or Copilot Pro (personal).
What Do You Need Before Starting?
- A Microsoft 365 Copilot license (business, ~$41 CAD/user/month) or Copilot Pro (personal). Plan comparison in our Copilot pricing guide.
- Word for Windows, Mac, or Word on the web, signed into the account that holds the license.
- If the icon is missing or greyed out: check File → Account for the right identity, update Office, and confirm your admin assigned the license.
How Do You Draft a Document From Scratch?
- Open a blank document — the Draft with Copilot prompt appears automatically (or click the ribbon icon).
- Write a real brief, not a topic: "A one-page proposal for janitorial services for a 40,000 sq ft office, professional tone, sections for scope, schedule, and pricing placeholders."
- Reference your own files with /filename so the draft pulls from existing content — past proposals, reports, notes.
- Choose Keep it, Regenerate, or type an adjustment ("add a testimonials section"). Then edit as you would any draft.
How Do You Rewrite Existing Text?
- Select the paragraph or section, then click the Copilot icon in the left margin.
- Choose Auto Rewrite for alternatives, or give a directive: "half the length," "plainer language," "more confident."
- Cycle the options and Replace or Insert below. The same menu converts selected text into a table.
How Do You Summarize or Question a Document?
Open the Copilot chat pane from the ribbon and ask directly: "summarize this document in five bullets," "list every deadline and who owns it," "what are the termination conditions in this contract?" Answers carry citations that jump to the source passage — verify anything contractual against the cited text before acting on it.
Frequently Asked Questions
Do I need a license to use Copilot in Word?
Yes. Copilot in Word requires either a Microsoft 365 Copilot add-on license (~$41 CAD/user/month on a qualifying business plan) or Copilot Pro for personal Microsoft 365 accounts. It works in Word for Windows, Mac, and Word on the web once the license is assigned.
How do I get Copilot to write a document in Word?
Open a blank document and the "Draft with Copilot" box appears (or press the Copilot icon in the ribbon). Describe the document — audience, purpose, key points, length — and Copilot generates a full draft. You can reference existing files ("base it on /Q2-report") so the draft uses your own content. Then Keep it, Regenerate, or refine with a follow-up instruction.
Can Copilot rewrite or shorten my existing text?
Yes. Select any text and choose the Copilot icon in the left margin → "Auto Rewrite" for alternatives, or give a specific instruction like "make this half the length" or "make it more formal." Copilot shows options you can insert, replace, or discard. You can also convert selected text into a table.
How do I summarize a long Word document with Copilot?
Open the Copilot chat pane (ribbon icon) and ask "summarize this document" — or more specifically, "give me the five key commitments in this contract with page references." Copilot answers with citations that jump to the relevant section. This works on documents up to very substantial lengths, making it the fastest way to triage long reports.
Why is Copilot greyed out in Word?
Almost always licensing or account: you are signed into a personal account while the license is on your work account (or vice versa), the admin has not assigned the Copilot license, or the app needs an update. Check File → Account for the signed-in identity and update Office; the Copilot icon appears once a licensed account is active.
