On July 23, 2026, Microsoft’s Corporate, External, and Legal Affairs (CELA) organization announced the internal deployment of Harvey’s AI platform. This adoption covers roughly 2,000 legal and compliance professionals, marking an important step in applying AI to enhance Microsoft’s internal legal operations. The announcement underscores Microsoft's commitment to streamlined, AI-aided workflows.
Harvey’s AI is integrated directly into Microsoft 365 Copilot and Copilot Cowork, enabling legal teams to use AI-assisted insights in familiar applications such as Word, Outlook, and Teams. This integration allows legal professionals to seamlessly access specialized legal intelligence without leaving their workflow.
The collaboration extends a relationship going back to December 2024, when Harvey connected its platform with Microsoft tools like SharePoint and Word, embedding advanced legal intelligence deeper into Microsoft’s ecosystem. According to coverage from LawNext, the partnership has since matured to include more operational uses and tighter integration.
Harvey’s AI platform provides a broad range of functions including legal research, contract and document analysis, deal management, fund formation, due diligence, and knowledge retrieval based on trusted sources. This array of tools aims to reduce manual workload and enable legal teams to concentrate on higher-value work, as noted by Antony Cook, Microsoft’s Corporate Vice President and Deputy General Counsel.
Winston Weinberg, CEO of Harvey, said the deepening alliance follows a long-standing collaboration and looks forward to growing their joint efforts globally.
