LegiMatch vs Lexis+ AI
LegiMatch vs Lexis+ AI: a side-by-side for solo and small firms
Lexis+ AI pairs LexisNexis's content and Shepard's citator with an AI assistant, Protégé, for research and drafting. LegiMatch is a smaller, focused tool for finding similar decisions and checking briefs. This page compares them task by task.
Research approach
Lexis+ AI answers questions in conversation and drafts with Protégé, drawing on LexisNexis content. LegiMatch starts from your facts and returns a ranked list of similar decisions, each with its outcome, key passages and the reasons it matched.
Citator
Shepard's is a comprehensive editorial citator. LegiMatch's good-law flags come from later decisions in its own database and show the treating sentence; they help you triage, and a full citator remains the final check.
Price and contract
LexisNexis quotes Lexis+ AI per firm, typically on annual terms. LegiMatch publishes its prices and runs month to month.
