WhatsApp AI Agent with Knowledge Base
Answer common customer questions on WhatsApp automatically using an AI agent grounded in your own documents.
The automation chain
Business problem
Customer support teams answer the same questions repeatedly on WhatsApp — pricing, hours, policies, product details — taking time away from more complex issues.
Before automation
A support agent reads every incoming WhatsApp message and types a reply manually, even for frequently repeated questions.
The automated workflow
n8n routes incoming WhatsApp messages to an AI agent that searches your knowledge base (FAQs, policies, product info) and replies automatically, escalating to a human when it isn't confident.
How it works
