Comparison
Frix vs LexisNexis
LexisNexis pairs a comprehensive editorial research database with Shepard's, the oldest citator, and Lexis+ AI with its Protégé assistant for research and drafting; it is sold by subscription to firms of every size. Frix offers the public record free with an automated citator, an AI that cites the page from both the library and your own files, and the operational side of a firm, in one product you can start using today.
Choose Frix if
- You want to Shepardize-style check a case, read every citing sentence and pull the statute without a subscription.
- Your research questions start from the facts in your own file, not from a search box.
- You want intake, matters and drafting in the same place as research.
Choose LexisNexis if
- You depend on Shepard's editorial signals and Lexis's secondary sources (Matthew Bender treatises, practice guides).
- You need state administrative codes, historical statute versions and international material.
- Your firm is already on Lexis tools like CounselLink or Juris.

Shepard's versus an automated citator
Shepard's has been telling lawyers whether a case is still good since the 1870s, and its signals are checked by editors. Frix's citator does the same job by reading the public record: it finds every later opinion that cites the case, shows you the sentence it was cited in, and flags negative treatment. It is faster to get to and free, and it will occasionally be wrong in ways an editor would catch, which is why the citing sentence is always one click away. We explain the difference in plain terms in what a citator is.
Research that starts from your file
Lexis+ AI is a very good search box with an assistant attached. Donna is an assistant that already has your file open. Ask whether the limitations argument in a medical negligence matter holds up, and she reads the complaint and the discovery in your vault, searches the library for the controlling cases, runs the citator on them, and answers with numbered citations that open either the opinion or the page of your own record. That workflow, more than any one feature, is what firms tell us they were missing.
What you give up
Editorial secondary sources. If your practice leans on treatises and practice guides, Lexis has decades of them and Frix has none. Coverage of state administrative codes is partial in Frix today. And Lexis's judicial analytics products go far deeper than Frix's judge profiles, which are built from the public record of opinions, positions and financial disclosures.
