A Claude legal AI system processes documents by sending them directly to the 200K context window, eliminating the complexity and information loss of RAG-based chunking for most legal documents. For contract review, the entire agreement is analyzed in one pass — extracting key terms, identifying unusual clauses, flagging risk areas, and comparing against standard templates. For legal research, a RAG pipeline indexes case law databases and Claude synthesizes findings with proper citations and reasoning chains.
Litigation support workflows process document productions, categorizing relevance and privilege status at scale. Brief drafting assistants generate first drafts based on case facts and applicable precedent, with structured output ensuring proper legal formatting. All outputs include confidence indicators and are routed to attorney review queues.
Comprehensive audit trails satisfy bar association ethics requirements for AI use in legal practice.
