Cumbuca's Regulus targets Pix, Open Finance compliance

The smart part here is the narrow scope: a source-grounded assistant for regulated finance is much more credible than a general LLM pretending to understand law.

• –Cumbuca says Regulus is trained only on official Banco Central materials, which should reduce hallucinations and make answers easier to audit.
• –The use case is clear: compliance, product, and engineering teams can sanity-check regulatory questions before escalating to legal.
• –WhatsApp access lowers friction, but the real product value is the citation trail back to the original normatives.
• –The limitation is also clear: this is useful for Open Finance and Pix, not a broad Brazilian legal research tool.
