Regulus by Cumbuca - AI chatbot trained on Brazil's Central Bank regulations

Hey PH! Bruno here, COO at Cumbuca. We're a Payment Institution in Brazil, which means we live and breathe Central Bank regulation every single day. Open Finance, Pix, SCR — our team has to stay on top of hundreds of normatives, circulars, and technical specs that change regularly. Here's what frustrated us: when you ask ChatGPT or Claude about Brazilian financial regulation, you get confident-sounding answers that are often wrong. These models weren't trained on the specific normatives, and the stakes are too high for "close enough." So our data engineering team built Regulus — an AI chatbot trained exclusively on official Central Bank sources. It covers Open Finance and Pix regulations (normatives, technical documentation, message catalogs). When it gives you an answer, it points to the source. **Who this is for:** - Compliance officers at small fintechs who don't have a 10-person legal team - Product managers who need to check "can we legally do X?" before building - Developers who need to find specific technical requirements in regulatory docs It's free to use. We built it because we believe that lowering the barrier to understanding regulation makes the whole ecosystem better. More people playing by the rules = a healthier market. Right now it covers Open Finance and Pix. If there's demand, we'll expand to other areas of financial regulation. This is part of Cumbuca Launch Week — we're shipping 5 tools this week to make Brazil's financial ecosystem more accessible. Curious to hear from you: - Have you ever been burned by wrong AI answers on regulatory questions? What happened? - If you work in compliance — what's the regulation you spend the most time deciphering? - What other areas of financial regulation should we cover next?
