LitCo · legal research

Legal research on Litco’s own corpus.

Research, Litco’s legal research library, covers federal and most state appellate case law, with new decisions arriving within days of being handed down. Ana sits beside every result, so litigators can question a case or check a citation without leaving the page. Litco flags a case as bad law only after two independent readings agree.

Ana runs the search for you.

Search with terms and connectors or in plain English, filter by jurisdiction, and read highlighted excerpts from the opinions themselves. Or skip writing the search: tell Ana what you are looking for, and it composes the queries, runs them, reads the results, and reports back with verified citations.

Open an opinion in Research and the treatment history sits at the top of the page, along with the date the law is current through. Ana reads every citing decision to judge whether the case is still good law. Research flags a case as overruled only when two independent readings agree. When a call is close, Research routes the question to a more capable model that can draw finer distinctions before any flag appears.

A page for every judge in the corpus.

Litco builds a page for every judge in the corpus, 10,539 of them, from the opinions. Lawyers can read what the judge has written year by year and which authorities the judge cites most. They can see who cites the judge and how the judge’s decisions have fared on review. The incumbent platforms sell judge analytics as a premium add-on, while Litco includes the judge pages in the library.
