Who it is for
Brazilian lawyers, law students, and anyone who needs the text of a statute together with its citation.
Letra da Lei
Brazilian statutes and precedent with sourced citations
Overview
What Letra da Lei does
Letra da Lei is a research tool for Brazilian law. A question about a legal situation returns the statutes and court decisions that bear on it, quoted at length, with the citation and a link back to the official publication.
The design point is that every answer traces to a document the app actually retrieved. Its skills cover petitions, general research, legal grounding, replies to claims, and case analysis.
Work is done in Portuguese, as in the sample question about how long a consumer has to withdraw from an online purchase under the CDC. The developer states plainly that none of this is legal advice.
What stands out
Answers carry the full legal text and a link to the official source rather than a paraphrase.

Where Letra da Lei is listed
Letra da Lei is listed in the ChatGPT apps directory only. Letra da Lei has no connector under the same domain in the Claude directory; 392 of the 3,150 products here are on both marketplaces, and this is not one of them.
ChatGPT apps are built on MCP, and the same server can back a Claude connector, so the absence is a distribution decision rather than a technical one.
