The setup, deployed via Docker on GPU-enabled instances, processes thousands of documents monthly at zero marginal cost while maintaining GDPR and HIPAA compliance.", "body_md": "Companies want the power of AI to automate document parsing, lead scoring, and internal workflows. However, sending sensitive financial data, legal contracts, or customer PII to OpenAI's public API is often a massive compliance violation.\n\nThe solution? Self-hosted, programmatic AI workflows. In this tear-down, I demonstrate how to build a fully automated, privacy-first lead generation and processing engine using **n8n** and **Local LLMs (Ollama)**.\n\nInstead of Zapier (expensive, cloud-only), we deploy n8n via Docker. n8n is a powerful workflow automation tool that can be entirely self-hosted. It connects to our local database, CRM, and email server without any data leaving our VPC.\n\nWe provision a GPU-enabled instance (or pass through a GPU in Proxmox) and run **Ollama**. Ollama serves open-source LLMs like Meta's Llama 3 or Mistral directly via a local API. This means our AI processing happens entirely on-premise.\n\nHere is a practical example of a workflow we automated for a B2B client:\n\n`http://ollama:11434/api/generate`\n\n) with a prompt to extract key entities: \"Extract the Company Name, Deal Value, and Key Clauses from this text and return it as strict JSON.\"This system processes thousands of documents per month at zero marginal cost (no API fees) while maintaining 100% data privacy and GDPR/HIPAA compliance.\n\n*Want to automate your business processes without compromising security?
