LGPD Sentinel AI — Open source LGPD compliance automation with local AI (FastAPI + LangChain + Ollama)

The Problem Brazilian companies are being fined by ANPD (Brazil's data protection authority) for LGPD non-compliance. LGPD is Brazil's GDPR equivalent — and it requires mandatory personal data mapping plus DPIA (Data Protection Impact Assessment) reports. The existing tools cost US$500+/month (Osano, OneTrust, TrustArc). SMEs and startups simply can't afford that. The Solution LGPD Sentinel AI is a 100% open source tool (Apache 2.0) that automates LGPD compliance audits using local AI via Ollama (Mistral, Llama3, Gemma). Zero data leaves your server. Everything runs on your own infrastructure. What's already built (v0.1.0-alpha) FastAPI endpoints for automated personal data mapping DPIA/RIPD generation with AI (LangChain + Ollama) Automatic risk scoring by LGPD category Specialized PT-BR prompts Docker + docker-compose (up in 2 commands) GitHub Actions CI/CD with tests + Trivy security scan Support for Mistral 7B, Llama3, Gemma via Ollama Tech Stack (all open source, all free) Layer To
