What is n8n? — Introduction
n8n in one sentence
n8n is a visual, no-code automation tool that connects apps and services into "workflows" — when X happens, do Y, then Z — without writing backend code.
Why it matters for AI builders
n8n has native AI nodes (ChatGPT, Claude, and more), so you can build real AI-powered automations — auto-replying to emails, summarizing form submissions, generating content — as a builder with zero coding background.
Self-hosted vs cloud
n8n Cloud is the easiest starting point (hosted, no setup). Self-hosting (Docker) is free but requires server management. Start with Cloud's free tier while learning.
