Lexi is an AI legal research tool designed to help solo attorneys and small law firm practitioners answer legal questions quickly and accurately using natural language queries that return cited legal analysis. Rather than navigating complex Boolean search interfaces of traditional legal databases, users ask Lexi questions in plain language — "What are the elements of tortious interference in California?" or "Can an employer require employees to sign arbitration agreements in New York?" — and receive organized answers with citations to relevant cases and statutes.

Grok 3, released in February 2025, achieved top scores on the AIME math reasoning benchmark and ARC-AGI test, briefly positioning xAI as a frontier model lab.
