What It Does
n8n is an open-source workflow automation tool that you can self-host, meaning your data never leaves your server. It offers a visual node-based editor similar to Make, with over 400 integrations and a code node for custom JavaScript or Python. For AI workflows, n8n has dedicated nodes for OpenAI, Anthropic, Hugging Face, and vector databases, making it a popular choice for building AI agents and RAG pipelines without writing a full application.
Setup in 5 Minutes
.
- To self-host, run
docker run -it –rm -p 5678:5678 n8nio/n8n and open
localhost:5678 in your browser.
- Create your first workflow by adding a trigger node and connecting
action nodes.
- n8n's community templates include hundreds of ready-made AI
workflows.
Try This
Import the community template "AI Agent with Memory" from the n8n
template library. Configure it with your OpenAI or Anthropic API key.
This gives you a conversational AI agent that remembers previous
interactions using a vector store. Test it, then modify the system prompt
to specialise it for a specific task (customer support, research
assistant, study buddy).
Follow Along
Follow Along — AI Research Agent:
node and connect it to a Set node where you define a research topic (e.g. "latest advances in battery recycling").
- Add an HTTP Request node to call a web search API (SerpAPI or Brave Search) with the topic as the query. Extract the top five result URLs and snippets.
- Connect an OpenAI (or Anthropic) node. Pass the snippets in and prompt: "Summarise these search results into a 200-word research briefing with key findings and sources."
- Add a Send Email node that delivers the briefing to your inbox with the subject line "AI Research Brief: [topic]".
- Run the workflow end-to-end, check your inbox, and evaluate the summary quality.
