Copilot, Microsoft's assistant, has offered since October 15 more than 20 skills designed for lawyers, open to its customers in any country. In Word they help go over and write contracts, and in Cowork they keep count of deadlines, obligations and case chronologies. With them, partner plugins such as Harvey and Docusign are starting to appear, and Microsoft puts the edits made in Frontier at nearly 100,000.
Microsoft announced on Thursday, October 15, that more than 20 legal skills for Copilot, its AI assistant, are now generally available to its Copilot customers around the world. As legal plugins, they bring together what the company had earlier introduced under the name Legal Agent, its tool for reviewing contracts and marking up changes.
In Word, Copilot can check an agreement against a team's guidelines and suggest edits that Word applies as tracked changes while keeping the formatting, or draft a new contract from approved precedents stored in SharePoint. In Cowork, the space for handing off multi-step tasks, it can follow deadlines and obligations across contract portfolios, compare key clauses between agreements or put together case chronologies. Later this month, a Word feature for jumping between a document's defined terms and their definitions will enter preview.
From the same day, partner plugins covering legal research, document management, e-signature, legal AI and e-discovery are starting to arrive through Microsoft's plugin registry, among them Relativity, Harvey, Docusign and Bloomberg Law; more will follow over time.
According to Microsoft, since the tool opened to its Frontier early access program in April, users of the program, more than 1,800 of them, have produced nearly 100,000 edits and kept roughly seven in ten suggestions. The company stresses that legal teams stay in control at every step: Copilot only applies proposed changes once the user approves them, works solely with content each person can access and does not use documents or conversations to train the underlying foundation models. The announcement does not give pricing.
In five months, four big AI companies have launched a dedicated offering for the legal sector, as LawSites notes: Anthropic in May, Google in August, OpenAI in September and now Microsoft.
Why it matters · analysis and opinion
Microsoft's trump card is the place where lawyers already work: contracts are negotiated in Word, and the AI arrives in that same document without asking anyone to switch tools. For law firms and in-house legal teams that already pay for Copilot, the question is no longer whether to try AI but under what rules: which precedents and review guidelines it is given, and who validates each change before sending it to the other side. The partner plugins sketch out a market in which specialized legal tools connect to the big assistants instead of competing with them. Cost and performance outside the teams that have tested it are still to be seen. A small firm can start with low-risk contracts and measure how much time it really saves.
