I Built an Entire App with OpenAI's Codex and 8 AI Agent Employees

Alex and Greg demonstrate a complete workflow for building an app from scratch using AI. They start by using IdeaBrowser to find and validate a high-growth 'wellness app' trend. They then use ChatGPT to generate a PRD for 'Habit Flow', an adaptive AI wellness tracker, and proceed to build the MVP live using OpenAI's Codex.
