LexisNexis, owned by RELX, provides computer-assisted legal research (CALR) through its AI-powered platform, Lexis+. The platform integrates legal research, practical guidance, and analytical tools to serve legal professionals, corporations, government agencies, and academic institutions. Revenue is generated through paid subscriptions to its various web portals.
The company's history dates back to 1970 when Mead Data Central, under the leadership of its first president H. Donald Wilson, developed the LEXIS database. It was publicly launched in 1973, becoming one of the first services to allow end-users, primarily lawyers, to interact directly with large electronic databases. By 1980, LEXIS had digitized all available U.S. federal and state cases. LexisNexis is now a global provider of information and analytics, with the world's largest electronic database for legal and public-records information as of 2006.
The core of the business is the Lexis+ platform, which utilizes artificial intelligence, including generative AI and large language models from Anthropic and OpenAI, to enhance its services. Key features include conversational search, document summarization, automated drafting of legal documents like memos and briefs, and document analysis. The platform also offers tools like Shepard's for citation analysis, Code Compare for statutory research, and Litigation Analytics for insights on judges and courts. In 2025, LexisNexis introduced Protégé, a personalized AI legal assistant. This technology, built on a retrieval-augmented generation (RAG) framework to ensure accuracy and reduce hallucinations, allows users to get answers from a vast repository of licensed legal, news, and business content.
