Microsoft adds legal skills and plugins to Copilot

Microsoft says its legal capabilities are generally available worldwide to Microsoft Copilot customers.[2] Its Support page specifies that the legal plugins are available in Copilot in Word and Cowork for commercial Microsoft 365 Copilot subscribers.[3] The distinction matters for purchasing and rollout decisions: the broad availability statement and the plugin-specific subscription requirement describe different parts of the offering. Microsoft says partner-built plugins are beginning to roll out through its plugin registry, with more to come over time.[1]

Microsoft says the capabilities build on Legal Agent and now come together as legal plugins in Copilot.[1] The listed tasks include reviewing agreements against playbooks, identifying terms needing attention and proposing tracked edits.[1] Other capabilities extract commitments, deadlines and triggers, then trace related agreements to determine which terms remain in force.[1] The tools can also compare key terms across agreements, build case chronologies, and surface dates and open questions from meeting materials.[1] For teams, these examples point to assistance across document review and matter organization, rather than a single contract-review workflow.

Microsoft says the legal capabilities support deeper document work in Word and multi-file, multi-step work in Cowork.[1] In Word, an edit is applied as a native tracked change and preserves the document’s formatting.[1] Copilot can draw on approved SharePoint precedents and use Word content controls for structured placeholders.[1] Microsoft also describes turning approved precedents and templates into new agreements or structured legal memos.[1] These features could help legal teams keep drafting closer to their existing document practices, while Cowork is positioned for work that spans files and steps.

Microsoft says that since the Frontier release in April, more than 1,800 users generated nearly 100,000 edits, and users chose to keep roughly seven in ten suggestions.[1] It also reports evaluation results of more than 90% fluency, more than 95% conciseness and more than 85% relevance.[1] Microsoft says its own legal organization is an early proving ground for the experiences.[1] LawNext describes Microsoft as the fourth major AI company to introduce a dedicated legal offering in five months, after Anthropic, Google and OpenAI, and says Word could distinguish Microsoft’s product because lawyers already work in it.[2]
