LegalTech platform orchestrates seven sequential interaction phases from user authentication through AI-driven document generation and billing. User browser initiates JWT-based auth with backend API, then sends chat messages routed through Chat Engine to AI Agents and Tool Orchestrator for processing. File uploads trigger RAG indexing via Files Pipeline and Retrieval Gateway, while Workflow Engine coordinates canvas updates and Template Service generates legal documents with external Legal Corpus Search integration. Analytics and Tarrification services track LLM usage and billing in real time. This architecture demonstrates how to integrate authentication, conversational AI, document retrieval, workflow automation, and monetization into a cohesive legal tech platform.
