AI Agent Node in n8n: Build a Smart Chatbot
AI Agent Node in n8n explained — and a full “Simple Chatbot” project build.
In this video, I break down what an AI agent is, how it connects to your LLM (OpenAI / Anthropic / Gemini), and how to add memory so your chatbot actually remembers the conversation.
What you’ll learn:
What an AI agent is (in practical workflow terms)
Why a chat model (LLM) is mandatory for the AI Agent node
System message: how to define the agent’s role and behavior
Tools + memory: what they do and when to use them
Output formatting (Output Parser) — what it is and why it matters
Connecting OpenAI credentials + generating an API key
Testing the chatbot in chat and verifying memory works
Next step: preparing this chatbot for website integration (in the next video)
