LexisNexis is one of the two dominant legal research platforms (alongside Thomson Reuters Westlaw) — providing access to case law, statutes, regulations, secondary sources, and legal analytics across US and international jurisdictions. Lexis+ AI is LexisNexis's generative AI legal research assistant — providing conversational legal research that synthesises case law, identifies relevant authorities, drafts research memos, and answers legal questions with citations. The AI is trained specifically for legal research and citing only verified legal sources rather than hallucinating citations, addressing the critical accuracy requirement for legal research. Lex Machina (LexisNexis acquisition) provides litigation analytics — judicial analytics showing how specific judges rule on specific motion types, opposing counsel analytics, party analytics, and case outcome prediction. CounselLink provides corporate legal department spend management and matter management. Legal analytics tools provide data-driven insights on litigation strategy — which arguments succeed, which courts are favourable, and how opposing counsel performs across different matter types. With millions of legal professionals using LexisNexis globally, it is one of the foundational legal infrastructure providers worldwide.
LexisNexis AI runs as llm assistant software built around text and data workflows. Users typically start with a prompt, upload, or connected data source, and the underlying model handles the heavy lifting before returning a result you can refine or export. It's available on web, ios, and android.
