Automated AI-Driven WhatsApp Support System

This n8n workflow creates an intelligent support assistant that integrates WhatsApp messaging, Google Docs, and AI language models (Google Gemini or OpenAI). It automates responses to user inquiries by fetching relevant business documents, processing real-time messages, and generating accurate, context-aware replies within a 24-hour window. The workflow begins with a Webhook that captures WhatsApp messages, checks message recency, prepares a custom prompt including date and document content, and sends it to an AI model. The response is cleaned, stored, and sent back via WhatsApp, providing instant support without manual intervention. This setup is ideal for customer support, FAQs, or internal helpdesk automation.
