N8N is an AI workflow automation tool, similar to Zapier, but open-source and self hosted. It allows for creation of workflows with code or no-code approaches.
From what I can tell there's no AI in the product itself, but building automation workflows can integrate AI agents as needed. e.g. building a Slack response bot that somewhere in the workflow communicates with an LLM or something scraping a docsite.
There's a lot of hype around it right now as a way to inject AI into business use cases, similar to [[20250811104331-ai-mcp]]
