Microsoft Introduces Legal Agent AI Tool for Contract Review in Word

Microsoft has launched Legal Agent, a new AI tool for Microsoft Word, aimed at improving contract reviews and legal workflows. The company announced that Legal Agent uses agent-based AI to handle structured and repeatable legal tasks with greater consistency and accuracy. This tool is designed specifically for legal professionals and operates on predefined workflows, reflecting how legal teams review agreements.

Key Highlights

• Microsoft launches Legal Agent AI tool for contract review in Word.
• Legal Agent analyzes contracts clause by clause and compares versions.
• Tool integrates with Microsoft 365 and is available through the Frontier program.

Key Features of Legal Agent

Legal Agent performs clause-by-clause analysis of contracts, comparing them against internal playbooks. It helps users identify risks, compare different contract versions, and highlight obligations. The tool links its recommendations directly to the source text, making verification easier for legal teams.

Legal Agent can also generate negotiation-ready edits with tracked changes. This allows lawyers to draft precise revisions while maintaining the original document’s formatting. The tool supports documents that have already been edited, ensuring compatibility with ongoing legal work.

Technical Capabilities and Integration

Microsoft states that Legal Agent uses a specialized engine that understands the structure of Word documents. It recognizes elements such as tables, lists, and formatting, not just visible text. This capability enables the tool to make consistent edits and reduces reliance on traditional large language model outputs for each change.

The tool works within the Microsoft 365 environment, ensuring that legal workflows remain protected by enterprise-grade governance controls. Legal Agent integrates directly with Word and can be accessed through Copilot, Microsoft’s AI assistant.

Availability and Feedback

Currently, Legal Agent is available only to users in the United States through Microsoft’s Frontier program. Microsoft plans to gather feedback from legal professionals before expanding its availability. The company emphasizes that the tool is intended to support, not replace, the work of legal teams.
