Practical Use Cases

Associates ask conversational research questions and receive answers with Shepardized citations they can trust for briefs. Litigators summarize deposition transcripts and extract key admissions. Transactional lawyers draft contract clauses grounded in firm precedent. Research teams generate research memos with source trails for partner review.
