This n8n workflow creates an intelligent chatbot system that leverages OpenAI’s language model for natural conversations. It initiates a chat via webhook, maintains chat history for context, and uses a custom agent to process interactions. Additionally, it performs data lookups in a MongoDB database to enhance responses. This setup is ideal for implementing AI assistants, customer support bots, or interactive query systems that require context retention and external data integration.
