Locked-down ChatGPT and Claude plus agentic tools for manual search, AML checks and conflict checks
Keystone Law said over half its lawyers used secured ChatGPT and Claude as it added agentic tools for compliance checks
Problem
Keystone's lawyers work as self-employed principals and need quick answers from the firm's operating manual and efficient compliance checks on clients.
Approach
The firm gave lawyers restricted versions of ChatGPT and Claude. It also built a tool combining generative and agentic AI to query its operating manual, and agentic tools for anti-money laundering source-of-funds checks and conflict checking. Chief executive James Knight described the tools in the results for the year to 31 January 2026.
Results
Takeaway
Keystone reported tool use, not a measured gain. Revenue rose almost 18%, but the firm did not say how much of that came from AI or from adding lawyers.
