WhatsApp AI Agent

A WhatsApp bot connected to a custom knowledge base using RAG. Small businesses use it to answer customer questions automatically without needing to reply manually every time.

The problem

Small businesses get the same customer questions over and over on WhatsApp. Answering each one manually does not scale and generic chatbots do not know the business well enough to be useful.

Approach

Connected the WhatsApp Business API to an n8n workflow. Incoming messages trigger a retrieval pipeline that matches the question against a business-specific knowledge base and generates a reply. The owner only gets pulled in for things the bot cannot handle.
