n8n AI Workflow Tutorial 2026: Build Your First AI-Powered Automation
n8n is the most capable open-source platform for building AI workflows in 2026. With native LangChain nodes, an AI Agent node, and vector store integrations baked in, you can connect GPT-4 or Claude to any API, database, or app — and run the whole thing for $5–10/month on a self-hosted VPS instead of $50+/month on Zapier or Make. Why n8n Is the Best Platform for AI Workflows in 2026 n8n is an open-source workflow automation platform that has emerged as the leading choice for AI-powered automations in 2026, backed by a $180M Series C in October 2025 and 45,000+ GitHub stars.

The platform now counts 500+ enterprise customers, 400+ integrations, and a 4.8/5 rating on G2. ...
