An intelligent WhatsApp chatbot powered by n8n automation workflows, AI agents, and RAG retrieval. Handles customer queries, books appointments, and syncs every conversation to a CRM — all without human intervention.
The client's team was buried in WhatsApp messages — manually replying to hundreds of enquiries daily, missing follow-ups, and losing leads. They needed a system that could handle volume without losing the personal touch.
THE SOLUTION
Built an n8n automation pipeline connecting WhatsApp Business API with an AI agent powered by RAG. Conversations are logged to Google Sheets and synced with CRM. The bot intelligently routes complex queries to humans only when needed.
THE FEATURES

Context-aware responses using retrieval-augmented generation

costs cut by more than half
