A Beginner's Guide to AI Automation with n8n

Published on Convert on 10/11/2025.

A short guide for anyone who wants to automate AI tasks but isn’t sure where to start.

• Why n8n: Automate multi-step AI jobs (e.g. pulling insights from user feedback) instead of repeating the same prompts by hand.
• Install: Use Docker to run n8n, set the port, then open it in your browser.
• Basics: Nodes = single actions. Workflows = chains of nodes. Each node has input → action → output.
• First chat tool: Add a Chat Trigger and a Basic LLM Chain with an Ollama subnode. Use host.docker.internal so n8n in Docker can talk to Ollama on your machine.
• Customise: Add a fixed prompt and use the chat only for the changing input (e.g. user feedback).

You end up with a small chat that talks to your local model—ready to extend into bigger workflows.
