LexVault lets small law firms upload their documents archive and ask questions in plain English — every answer cites the exact source document and page. Built for firms with 2–20 attorneys who can't afford enterprise tools but need real document intelligence. Includes AI search across all matters, conflict checking, AI drafting grounded in your own templates, data extraction, matter management, and a tamper-evident audit trail. Your data is isolated per firm and never used to train AI models.
