ℹ️ This course is a live 2 day workshop + office hours!
Chat is evolving from a text interface into an operating system.
Users no longer go to chat apps just to search. They book flights, buy products, and analyze data without leaving the conversation. ChatGPT now supports apps appearing directly in chats, allowing enterprises to control how they appear in AI conversations.
This course is the blueprint for Product Managers and Engineers ready to build in this new ecosystem. You will move beyond simple text bots and master ChatGPT Apps: interactive widgets that bridge the gap between AI conversation and real-world transactions.
In this hands-on cohort, you will:
Build Interactive Apps: Create apps that let users interact with your product directly inside the chat.
Master the Architecture: Deep dive into the Model Context Protocol (MCP) to securely connect your backend tools to AI agents.
Ship a Real Product: From configuring your server to implementing OAuth, you will deploy a fully functional app live to users.
To ensure you ship fast, we’ll use Chippy, my custom vibe-coding tool built for this stack. It handles the complex backend so you can focus on shipping apps quickly.
