The fastest way to add Grammarly to Word

Install Grammarly's add-in directly from Microsoft's store, then sign in with your Grammarly account. The process takes about two minutes and works on both Windows and Mac versions of Word, as well as Word Online in your browser.

You do not need to buy Grammarly separately — if you already have a free Grammarly account, the add-in works with that. If you want Grammarly Premium features (like tone detection and plagiarism checking), you would need a Premium subscription, but the basic add-in installs the same way either way.

Key Takeaways

  • The Grammarly add-in installs from the Microsoft Store built into Word, not from Grammarly's website.
  • You need a Grammarly account (free or paid) to sign in after installation, but you can create one during the setup process.
  • After installation, Grammarly checks your writing in real time and shows suggestions directly in your Word document as you type.
  • The add-in works in Word on Windows, Word on Mac, and Word Online, but the steps differ slightly depending on which version you use.

Installing Grammarly on Word for Windows

Open Microsoft Word and start a new document or open an existing one. Click the Insert tab at the top of the screen, then look for Get Add-ins (it may also appear as a store icon). This opens the Microsoft Store window inside Word.

Search for "Grammarly" in the search box. The official Grammarly add-in will appear at the top of the results — it shows the Grammarly logo and is published by Grammarly, Inc. Click Add (or Get on some versions). Word will ask you to sign in to your Microsoft account if you are not already signed in. After you confirm, the add-in installs automatically.

Once installation finishes, a Grammarly panel opens on the right side of your Word window. Click Sign in and enter your Grammarly email and password. If you do not have a Grammarly account yet, click Create account instead and follow the prompts to set one up with your email address.

Installing Grammarly on Word for Mac

The Mac process is nearly identical. Open Word, click Insert in the menu bar, then select Get Add-ins. Search for "Grammarly" and click the official add-in when it appears. Click Add, and Word will prompt you to sign in to your Microsoft account.

After installation, the Grammarly panel appears on the right. Sign in with your Grammarly account credentials, or create a new account if you need one. On Mac, you may see a prompt asking Grammarly to access your documents — click Allow so the add-in can check your writing.

Installing Grammarly on Word Online

Word Online (the browser version you access at Office.com) uses a slightly different installation method. Open Word Online and create or open a document. Click the Insert tab, then select Get Add-ins.

Search for "Grammarly" and click the official add-in. Click Add, and you will be taken to a page asking you to sign in to your Microsoft account. After you sign in, Word Online will install the add-in. Return to your document — the Grammarly panel should now appear on the right side. Sign in with your Grammarly account to start using it.

What happens after you sign in

Once you are signed in, Grammarly begins checking your document automatically. You will see underlines and highlights appear as you type — blue underlines typically mark grammar and spelling issues, while other colors may indicate style suggestions or tone feedback (depending on whether you have Premium).

Click any underlined word or phrase to see Grammarly's suggestion. A small menu appears with the correction and an explanation of the issue. Click the suggestion to accept it, or click the X to dismiss it. You can also click the Grammarly panel on the right to see a full list of all issues in your document at once.

Troubleshooting if the add-in does not appear

If you installed Grammarly but the panel does not show up, try closing Word completely and opening it again. Sometimes the add-in needs a restart to activate.

If restarting does not work, go to Insert > Get Add-ins and search for Grammarly again. Look for a button that says Manage My Add-ins (usually at the bottom of the store window). If Grammarly appears in your list of installed add-ins but is turned off, click it and select Turn on.

On Word for Mac, if Grammarly does not appear after installation, check that you have allowed it permission to run. Go to Word > Preferences > Security and make sure Grammarly is not blocked.

Understanding what Grammarly can and cannot do in Word

The Grammarly add-in checks grammar, spelling, and punctuation in real time as you write. With a free account, you get basic corrections. With Grammarly Premium, you also get suggestions for tone, clarity, engagement, and plagiarism detection.

Grammarly does not rewrite your document for you — it flags issues and suggests changes, but you decide whether to accept each one. It also does not integrate with Word's built-in spell-check in a way that turns it off, so you may see both Grammarly and Word's own suggestions. You can ignore Word's suggestions if you prefer to use only Grammarly.

Frequently Asked Questions

Do I need to pay for Grammarly to use it in Word?

No. A free Grammarly account works with the Word add-in. Premium costs money and adds features like tone detection and plagiarism checking, but basic grammar and spelling checks work with the free version.

Can I use Grammarly in Word on my phone or tablet?

The Grammarly add-in does not work in Word on mobile devices. However, you can use the standalone Grammarly app on your phone or tablet, or copy and paste text into Grammarly.com to check it there.

Will Grammarly slow down Word?

Most users do not notice a slowdown, but on older computers or with very long documents, the add-in may cause slight delays as it checks your text. If you experience performance issues, you can turn off the add-in temporarily by going to Insert > Get Add-ins > Manage My Add-ins and clicking the toggle next to Grammarly.

What if I want to uninstall Grammarly from Word?

Go to Insert > Get Add-ins > Manage My Add-ins. Find Grammarly in the list, click the three dots next to it, and select Remove. The add-in will be uninstalled, though your Grammarly account remains active if you want to use it elsewhere.
