It uses n8n, MetaWebhook, OpenRouter, an AI agent, and a custom knowledge base stored in Google Docs to instantly understand questions, retrieve relevant information, and send answers back through Messenger. The workflow also escalates complex questions when needed and includes a Meta/Facebook verification step at the top of the setup. John demonstrates that sending a message triggers the verification, fetches knowledge-base information, and returns the response successfully.
