AI-Powered Chatbot with Memory and External Data Access

This n8n workflow creates an intelligent AI chatbot integrated with Google Gemini, capable of conversations, reasoning, and accessing real-time information. It starts with a webhook trigger to receive chat messages, which are then processed by an AI agent configured as a personal assistant. The AI uses a memory buffer to remember recent interactions and can invoke tools such as a reasoning step-by-step thinker, a factual search via SerpAPI, and a calculator for numerical tasks. The combination of these components enables the chatbot to provide accurate, well-reasoned, and up-to-date responses. This workflow is suitable for building sophisticated customer support bots, intelligent assistants, or information retrieval systems that require memory and external data integration.
