Use Microsoft Copilot for Document Research
Microsoft's official replacement for Smart Lookup is Copilot, which offers advanced AI-assisted research and definitions right inside Word.
As of January 1, 2025, Microsoft recommends using Copilot as the direct replacement for Smart Lookup. Note that unlike the previously free Smart Lookup tool, Copilot requires a paid Microsoft 365 subscription.
Click the Copilot icon located on the Home tab in the Word ribbon.
Type a prompt such as 'Define [word]' or 'Find information about [topic]' directly into the Copilot chat box.
Copilot will generate a summary, provide relevant definitions, and source information from the web.
Utilize Word's Built-in Thesaurus
For basic word synonyms and offline reference, you can still use the traditional proofing tools available in Microsoft Word.

Frequently Asked Questions
Why did Microsoft remove Smart Lookup from Word?
Microsoft discontinued Smart Lookup on January 1, 2025, to streamline its services and transition users toward their newer AI-driven tools, specifically Microsoft Copilot.
Can I get Smart Lookup back in older versions of Word?
No. Smart Lookup relied on cloud-based services powered by Bing. Because Microsoft deactivated the server-side functionality, it will no longer work even if you are using an older desktop version of Microsoft Word.
Is Microsoft Copilot free to use in Word?
No, integrating Copilot directly into the Microsoft Word interface requires a paid Microsoft 365 subscription and a Copilot Pro license. However, you can use the standalone Copilot web version for free in your browser.
How can I look up definitions in Word now?
You can use the built-in Thesaurus (Shift+F7) under the Review tab for synonyms. For comprehensive definitions or web searches, you will need to manually use a web browser or upgrade to a Copilot subscription.
