Introducing Ask LexisNexis®

Harvey integrates LexisNexis for citation-backed legal research.

Capability change

Harvey introduced Ask LexisNexis, a feature that allows users to ask legal questions in natural language and receive AI-generated answers with citations from LexisNexis, grounded in U.S. primary law content including federal and state case law, statutes, and administrative codes.

The feature is available in open beta for all Harvey users and includes Shepard's Citations Service to verify the validity of cited authorities.
