You’ll see how Claude Code can create a full voice AI agent in Retell AI, generate real functions, handle post-call analysis, and automatically build multiple n8n workflows for checking calendar availability, booking appointments, and routing calls based on urgency. This walkthrough covers how to connect voice AI with Google Calendar, Slack, and email, and how to assemble a real, client-ready AI system step by step — even if you don’t have a coding background. If you’re interested in voice AI, AI agents, n8n automations, or building sellable AI systems for businesses, this video shows how the process is changing with Claude Code.
