How Clifford Chance uses AI
Clifford Chance uses Microsoft-based AI across the firm. It built Clifford Chance Assist, a private generative AI tool on Azure OpenAI, deployed Copilot for Microsoft 365 to all staff in 2024, and in July 2026 launched an AI knowledge platform with Epiq and Microsoft. Its policy requires AI output for legal work to be checked by a qualified lawyer.

Tamarly Research conclusion
Clifford Chance has taken the platform route, building on Microsoft through Clifford Chance Assist, firmwide Copilot and the Knowledge Bank with Epiq. Its CTO reports that AI adoption at the firm reached 90% in 2025, and its November 2025 proposal to cut about 50 London business services roles cited greater AI use among the reasons. Where Kirkland & Ellis builds its own platform, Clifford Chance relies on a main vendor and requires a qualified lawyer to check AI output used in legal work.
