AILexEra connects nine million opinions, every federal and state statute, and 50 million citation edges into a single searchable network — powered by an AI agent that reasons across the full picture, not just a ranked list.
These capabilities require a structured knowledge graph as the foundation — not keyword search with an AI layer on top.
Over nine million court opinions connected by 53 million citation edges. Trace the doctrinal lineage of any legal principle across jurisdictions and decades.
Federal judge profiles enriched with financial disclosures, appointment history, and ruling patterns. Identify potential conflicts and predict tendencies with evidence.
Map which federal regulations have been litigated in which circuits, and surface areas where the law is unsettled. Critical for compliance and advisory work.
Submit any AI-drafted brief. Every citation is checked against the master database for existence, current treatment, and accurate representation of the holding.
Go beyond red and yellow flags. See exactly which propositions within a case have been affirmed, distinguished, or overruled — with the citing passages.
Describe your legal question in plain language. The agent searches the knowledge graph, assembles authorities, and produces a sourced memorandum with verifiable citations.
Integrate LexEra's knowledge graph directly into your firm's tools. Search cases, statutes, and regulations, traverse citation networks, and run AI analysis — all via authenticated REST endpoints with metered billing.
Verify citations, check treatment, and pull authorities without leaving your document. Coming soon for Microsoft Word and Google Docs.
