Understanding the challenge
The firm's best legal minds were spending their days on work that did not need them. Associates and paralegals lost hours to legal research, wading through discovery documents, and grinding out first drafts of memos and briefs, while partners billed less because their teams were buried. The firm had watched legal AI tools appear and wanted the leverage, but the fear was specific and serious: a tool that invented a case citation, misread a document, or sent privileged information somewhere it should not go was not a productivity problem, it was an ethics problem. So the firm held off, and its attorneys kept trading billable, high-judgment work for hours of manual review.
Our approach
The firm did not need a chatbot that spits out answers no one can trust. It needed agents that do the heavy lifting inside the firm's own systems, with an attorney signing off on everything. We designed a set of AI agents, each with a defined purpose, clear boundaries, and human approval on anything that touches a client or a filing:
• A legal research and analysis agent that finds relevant authority and summarizes it, drawing only from the firm's document management system and vetted sources so every citation traces back to a real one.
• A document-review agent that reads through discovery, flags the relevant and privileged material, and surfaces what an attorney needs to see first.
• A drafting agent that produces first drafts of memos and routine briefs from the matter file, so associates start from a working draft instead of a blank page.
• Human approval points, escalation rules, and monitoring on every output, so nothing reaches a client or a court without an attorney's review and sign-off.
Technical innovation
The core safeguard is that the agents retrieve rather than invent. The research and drafting agents work only from the firm's own matter files and vetted legal sources, so a citation always points to a real authority instead of a plausible-sounding fabrication, and every output is queued for an attorney to review, correct, and approve. Because the agents support multi-step work rather than one-off answers, an associate can hand off an entire research-and-first-draft sequence and get back a sourced, editable draft, with the confidentiality and privilege guardrails built into the workflow rather than left to chance.
Outcome
Time spent on legal research and first drafts fell by 58%, and that time went back to the work only attorneys can do: strategy, argument, and client counsel. Associates cleared discovery in a fraction of the time, first drafts arrived in hours instead of days, and because every citation was grounded in a real source and every output was attorney-approved, the firm got the leverage without the risk it had feared. "My associates are practicing law again instead of drowning in documents," the managing partner said. "And I never worry about what the AI might have made up, because it can only work from what is actually in the file."
