Microsoft Launches New Legal AI Agent in Word

Microsoft launched this week a new Legal Agent in Word designed to assist legal professionals working on legal documents. The new AI agent has been developed with legal engineers, and it’s available in early access in Word for Windows via Microsoft’s Frontier program.

This new Legal Agent in Word can draft edits in complex legal documents, inspecting citations, review tracked changes, and check contracts against internal playbooks. Microsoft says that legal teams remain in control of what the agent is doing, and they can review all edits and check comments created by the agent to explain suggested changes before applying them.

“Instead of relying on general AI models to interpret commands, the agent follows structured workflows shaped by real legal practice, managing clearly defined, repeatable tasks like reviewing contracts clause by clause against a playbook,” Microsoft explained. The new Legal Agent in Word also keeps sensitive workflows secure by being governed by the same Microsoft 365 security and compliance controls that organizations use for their legal documents.

To test this new Legal Agent in Word, organizations will need to join the Microsoft Frontier program from the Microsoft 365 Admin center and assign Microsoft 365 Copilot licenses to their users. Once enabled, the new AI agent will be available from the Copilot panel in Word for Windows.
