About OpisJuris

OpisJuris is a nationwide U.S. legal research platform that gives legal professionals instant access to primary legal authority — cases, statutes, regulations, court rules, and litigation documents — drawn from public-domain government sources and connected as a single national legal knowledge graph.

It is built for attorneys, paralegals, law students, and researchers who need to find governing authority quickly and verify it against the original source. Every result links back to the official government record, and a grounded AI research assistant answers legal questions using only indexed authority — never fabricating citations. Additional tools include a universal citator, jurisdiction comparison, case summarization, and a personal research workspace for saving and organizing authority.

OpisJuris is built by the OpisJuris team on the Base44 platform. Our mission is to make primary U.S. law freely searchable and to make legal research faster, more transparent, and grounded in real authority rather than guesswork. AI-generated analysis is always labeled and should be independently verified before reliance in legal proceedings.
