A detailed guide to n8n AI Agent: what it is, how it works, tutorials, workflows, tools, pricing, comparisons, and practical examples for automation and business.
Introduction to n8n AI Agent
n8n (pronounced "n-eight-n") is an open-source automation platform that connects apps, APIs, and AI models to create workflows. With its AI Agent capabilities, n8n enables autonomous decision-making, memory-based workflows, and intelligent task execution. AI Agents in n8n can process natural language prompts, use tools like HTTP requests and Google Sheets, store memory and knowledge base, and generate structured outputs.
Is n8n AI Agent Free?
Yes, n8n itself is free and open-source. You can self-host and use the AI Agent without cost. The core platform is open source under the Fair Code License. For teams or enterprises, n8n also offers a cloud-hosted version with pricing plans.
How Does n8n AI Agent Work?
You provide a prompt or instruction, tools (HTTP Request, Google Sheets, Web Search, or custom APIs), memory or knowledge base, and output format. The AI Agent reads the prompt, decides which tools to use, executes actions, and returns results. This is similar to frameworks like LangChain or MCP, but with n8n's drag-and-drop workflow builder.
n8n AI Agent Tutorial for Beginners
Install n8n via Docker, npm, or n8n Cloud. Add the AI Agent node in the workflow editor. Connect your AI provider (OpenAI, Anthropic, Google Gemini, or Ollama) and add API keys. Configure tools such as HTTP Request, Google Sheets, and Webhook. Run and test with a prompt like "Get the latest Bitcoin price and store it in Google Sheets."
