01

Challenge

A mid-size firm's associates were spending half their time on first-pass research — finding cases, summarising holdings, building memo skeletons. Generic legal LLM tools hallucinated citations. Trust was the blocker.

02

Approach

Designed a bounded agent with tool calls into approved legal databases. Every claim is traced to a real citation, every summary cites the holding paragraph, and the agent refuses to answer rather than invent. Senior associate review on every output before partner sign-off.

03

Outcome

Research time per matter down 68%, citation accuracy at 97%, and zero fabricated citations across four months of production traffic. Associates redirected to higher-value drafting and strategy.

Research time per matter down 68%, citation accuracy at 97%, and zero fabricated citations across four months of production traffic. The team owned this end-to-end.
