This n8n workflow establishes a robust, webhook-triggered conversational AI. It functions as a chatbot endpoint, receiving incoming requests via a webhook. The workflow critically leverages the 'Window Buffer Memory' node to maintain context and history for ongoing conversations, ensuring the AI remembers previous interactions within a session. The core intelligence is provided by the 'Chat OpenAI' node, which processes user input and generates natural language responses using a large language model. Finally, the 'Respond to Webhook' node sends the AI's generated reply back to the originating system or user. This setup is ideal for building interactive chatbots, customer support agents, or intelligent assistants that require persistent memory across multiple user turns, enabling dynamic and context-aware dialogues for various applications.
