Multi-Agent Healthcare Assistant with WhatsApp, GPT-4 & Google Sheets

Multi-Agent AI Healthcare Assistant Demo

⚠️ EDUCATIONAL DEMONSTRATION ONLY - NOT FOR PRODUCTION MEDICAL USE ⚠️

A comprehensive demonstration of n8n's advanced multi-agent AI orchestration capabilities, showcasing how to build sophisticated conversational AI systems with specialized agent coordination.

🎯 What This Demo Shows

Advanced Multi-Agent Architecture: Main Orchestrator Agent** - Traffic controller and decision maker Patient Registration Agent** - Specialized data collection and validation Appointment Scheduler Agent** - Complex multi-step booking workflows Medical Report Analyzer** - Document processing and analysis Prescription Medicine Analyzer** - Medicine verification and safety checks

Technical Learning Objectives: Multi-agent coordination patterns Conditional agent routing and tool selection Memory management across conversations Multi-modal input processing (text, audio, images, documents) Complex state management in AI workflows External system integration (Google Sheets, WhatsApp, OpenAI)

🏗️ Architecture Highlights

Multi-Modal Processing Pipeline: Text Messages** → Direct agent processing Audio Messages** → Transcription → Text processing → Audio response Images** → Vision analysis → Context integration Documents** → PDF extraction → Content analysis

Agent Specialization: Each agent has focused responsibilities and constraints Intelligent document classification and routing Context-aware tool selection Error handling and recovery mechanisms

Memory & State Management: Session-based conversation persistence Context sharing between specialized agents Multi-step workflow state tracking
