## Description
In this tutorial, I'll show you step-by-step how to build an advanced AI voice agent using the most powerful tech stack in 2025. We'll use Vapi AI, n8n (self-hostable), Supabase, and other production tools to create an agent that can pick up phones, book meetings, search the web, and even improve itself autonomously.
