What is Lexis+ AI?

AI-powered legal research platform providing comprehensive legal information and research tools for legal professionals.

Lexis+ AI is LexisNexis's flagship AI-powered legal research platform, combining access to over 80 billion curated legal documents with conversational AI search, automated drafting, and practice-area guidance tools designed for law firms and corporate legal departments. It is best suited for mid-size to large legal organizations that need authoritative, citation-backed research integrated into daily workflows.

The platform builds on decades of LexisNexis content aggregation—spanning case law, statutes, regulations, secondary sources, and international legal materials—and layers modern AI capabilities on top. The conversational search interface, branded Lexis Answers, lets attorneys type questions in plain English and receive direct answers with pinpointed source citations rather than long lists of documents to manually review. Search Term Maps provide a visual highlighting system that identifies the most relevant passages within lengthy court opinions and regulatory filings, significantly reducing the time attorneys spend scanning documents.
