About This Workflow
This n8n workflow empowers you to create a sophisticated web search chatbot by integrating the cutting-edge GPT-4o language model with the privacy-focused Brave Search API. The workflow begins by listening for incoming chat messages, then utilizes an AI Agent powered by GPT-4o to understand user queries. It intelligently retrieves and selects appropriate tools, specifically leveraging the MCP Brave Search tool to execute web searches. To ensure coherent conversations, a short-term memory buffer is maintained. This robust setup enables your chatbot to access and process real-time information from the web, delivering intelligent and contextually relevant responses.
