Building a Real-time Voice Agent with Cloudflare's Edge Stack

See a live demo of a real-time sales coaching app using Durable Objects, Workers AI, Vectorize, and R2 to achieve sub-second feedback loops.

Overview

Live demo of a sales pitch coaching app built entirely on Cloudflare: Durable Objects for stateful WebSocket sessions, Workers AI for real-time transcription and LLM inference, Vectorize for RAG, and R2 for document storage. I’ll walk through the architecture decisions, show how structured extraction beats naive RAG chunking, and demo the app coaching a live pitch with realtime insights and post-session scoring.
