This n8n workflow creates an intelligent AI chatbot that engages in conversations, remembers dialogue context, and stores interactions in a Supabase database. It begins with a webhook trigger to start the chat, utilizes OpenAI’s language model via Langchain to generate responses, accesses a smart AI agent for processing, and maintains conversation history through memory buffers. The completed interactions are saved into a Supabase database for future analysis or retrieval. This workflow is ideal for deploying advanced, context-aware chatbots on websites or platforms requiring persistent conversation data.
