WhatsApp AI Assistant for Automated Customer Support in Groups

This n8n workflow creates an intelligent WhatsApp AI assistant that handles customer inquiries automatically. Incoming messages trigger the system to reference a Google Docs knowledge base, process queries with OpenAI or Gemini AI, and respond instantly—eliminating manual intervention. It works seamlessly in one-on-one chats and WhatsApp groups, where the assistant can reply on behalf of the business.

Setup is straightforward: connect your WhatsApp via WhapAround, add your Google Doc ID for the knowledge base, configure the webhook, and link your AI API key. Optional PostgreSQL integration adds conversation memory for personalized follow-ups, plus custom branding and escalation rules.

Benefits include 24/7 support without staff, reduced response times, scalable handling of group discussions, and cost savings on support teams. Ideal for businesses like healthcare providers scheduling appointments, sports clubs managing inquiries, or any service needing quick, accurate AI-driven responses.

Use cases: Appointment booking confirmations, FAQ handling in support groups, product queries in community chats, or lead qualification—all powered by your documentation for contextually relevant replies.
