bcb.gov.br looks like a government or public body site, is ranked in the top 10,000 sites and was registered in 1996. It uses Cloudflare, Azure Front Door and Azure DNS; we found no traces of an AI site builder.
The page shows little text before its JavaScript runs, so we also read its own scripts (/main-U2VBCIOC.js, /assets/vlibras/vlibras-plugin.js) for traces.

Wikidata, the free knowledge base behind Wikipedia, lists this domain as the official website of these items. Volunteers write it; each item shows its sources.
What its robots.txt and robots tags ask of AI crawlers. Each crawler chooses whether to follow it.
Read from what the page says about itself; we haven’t checked whether it’s true.
No AI builder traces found.
Coding tools such as Cursor leave no traces, so this doesn’t mean a person made it.
