Solution 1Recommended

Verify Your Microsoft 365 Subscription and Sign-in Account

The Similarity Checker is a premium feature that requires an active Microsoft 365 subscription. Signing in with the wrong account will hide this feature.

Sometimes Word may log you out or switch to a free Microsoft account by default, which instantly disables premium Editor features and limits the panel to basic grammar and spelling checks.

1
Open Word Account Settings

Launch Microsoft Word and click on 'File' in the top-left corner. Then, select 'Account' from the menu on the bottom left.

2
Check User Information

Under 'User Information', look at the email address displayed. Confirm that this is the exact account linked to your paid Microsoft 365 subscription.

3
Verify Product Information

Under 'Product Information' on the right side, ensure it displays 'Subscription Product: Microsoft 365'. If it shows Office 2019 or 2021, the feature will not be available.

Verify Your Microsoft 365 Subscription and Sign-in Account
Standalone Versions Unsupported: Standalone desktop versions of Word (such as Office 2016, 2019, or 2021) do not include the Similarity Checker. It is an exclusive feature for Microsoft 365 subscribers.

Frequently Asked Questions

Why do I only see Corrections and Insights in the Microsoft Word Editor?

If your Editor pane only displays Corrections and Insights, you are likely either signed in with a free Microsoft account, using a non-subscription version of Office (like Office 2019/2021), or experiencing an account sync issue. The Similarity Checker requires a verified Microsoft 365 subscription.

Can I use the Similarity Checker in Word for Android or iOS?

No, the Similarity Checker is not currently available in mobile versions of Microsoft Word, including Word for Android and Word for iOS. To use this feature, you must access Word for Windows, Mac, or Word for the Web.

Is the Similarity Checker completely free to use?

No, the Similarity Checker is a premium feature tied to Microsoft 365 subscriptions (Personal, Family, Education, or Enterprise). Users with free Microsoft accounts do not have access to this tool.

Does the Similarity Checker check my entire document at once?

Yes, clicking on the Similarity Checker in the Editor pane will scan the entire text of your document against online sources, providing an overall percentage of similar text and highlighting areas that may need proper citations.
