Why Lawstronaut for Brazilian legal research
Brazilian legal information is spread across the federal legislation portal, superior courts, federal tribunals, tax and competition authorities, and sector regulators. For humans, that means slow research. For AI systems, it's a bigger problem: fragmented source access, inconsistent formats, missing provenance, and weak citation trails.
Lawstronaut turns those sources into one structured legal data layer — source links, metadata, full text, versioning, and API/MCP access. Your product or agent retrieves the legal source directly instead of relying on generic web search or unverified model memory. Every answer carries a citation, a timestamp, and a link to the official document — the provenance that makes a legal research platform defensible to auditors and regulators.
About Brazil legal coverage
Brazil is a civil-law federal republic. Consolidated federal legislation — from the Constitution and códigos to leis ordinárias, decretos, and medidas provisórias — is published by the Presidência da República on Planalto (www.planalto.gov.br). Case law coverage centres on the Superior Tribunal de Justiça, Brazil's highest court for non-constitutional federal-law matters, and the Turma Nacional de Uniformização, which harmonizes decisions of the federal small-claims courts. Administrative and regulatory materials come from CARF (tax appeals), CADE (competition), SUSEP (insurance), the Receita Federal, and the Advocacia-Geral da União. Records are published in Portuguese.
Brazilian law moves quickly: medidas provisórias take effect immediately and lapse or convert within months, tax rules change constantly across CARF and Receita Federal materials, and the LGPD data-protection regime continues to develop through regulation and enforcement. Point-in-time data straight from the source is what keeps a Brazilian legal research answer correct today.
