Descrybe Legal Engine for Microsoft 365 Copilot
Bring source-grounded legal research into Microsoft 365 Copilot.
Use Descrybe Legal Engine as a Microsoft-published Source in Copilot Chat, Researcher, and Cowork. Descrybe is enabled by default for Microsoft 365 tenants unless an administrator disables it, so lawyers can connect from Copilot Sources without manually configuring an MCP connection.

Legal Research Toolkit
Research the law, then carry it into Microsoft 365 work product.
Descrybe provides the research capabilities. Copilot provides the environment where you ask, refine, and use the result.
Check what supports the answer
Resolve citations, retrieve focused source passages, verify quoted language, and inspect the authorities behind the analysis.
Review treatment and citing cases
Research how later courts have treated an authority and find the citing decisions that matter to the issue.
Legal workflow ideas
Ask for the outcome—not just a case search.
These examples show what becomes possible when the surrounding assistant or application combines its own reading, reasoning, and work-product capabilities with focused Descrybe tools. They are ideas for use rather than separate product modes; the exact sequence and available steps depend on the host, its settings, and the context you choose to provide.
Everyday idea
Research from Copilot Chat
Start in Copilot Chat or Researcher with a legal question. Copilot can clarify the facts and jurisdiction, search cases and non-case primary law with Descrybe, and organize the results for source review.

Review authorities from a Microsoft 365 document
Working from a brief the user can access in Microsoft 365, Cowork can organize a citation and quotation review with Descrybe and prepare the findings in Word. For a structured review report, use Descrybe Review in the Platform.

Check a proposition in a draft
Start with a proposition in a draft or internal practice note. Copilot can ask Descrybe for authority that supports, limits, distinguishes, or contradicts it and surface the differences a lawyer should examine.

How it fits your work
Move from legal research to work product in Microsoft 365.
- Use Descrybe from supported experiences including Copilot Chat, Researcher, and Cowork.
- Research and verify primary law before using the result in a memo, letter, or other work product.
- In Cowork, carry Descrybe-backed research into a Microsoft Word document in the same workflow.
A qualifying Microsoft 365 Copilot license is required and is separate from Descrybe access.
