Descriptions:
This video walks through the complete construction of a voice AI system for a fictional HVAC business using Claude Code, Retell AI, and n8n — without writing a single line of code manually. The creator shows how a single comprehensive prompt fed into Claude Code generates a full frontend interface, custom voice agent functions, post-call data extraction logic, and three separate n8n workflows covering calendar availability checks, appointment booking, and post-call webhook routing.
The demonstration reveals how Claude Code communicates directly with Retell AI’s API to create and configure the agent, and with n8n’s cloud API to build and publish functional workflows. Live execution logs show all three workflows running successfully, confirming the system is production-ready rather than just a prototype.
The tutorial is designed for non-developers — no coding background is required, and the creator provides free access to the exact prompts used via a community classroom platform. Setup requires a Claude Pro subscription ($20/month), a free Retell AI account, and an n8n cloud instance. For anyone building AI-powered voice agents for business clients, this video offers a practical, replicable starting point that sidesteps the usual manual integration work.
