A Strategic Guide to Building ChatGPT Apps

For the last decade, building an app meant friction.

To book a flight, edit a photo, or check a price — you had to find an app, download it, create an account, learn its interface, and navigate through menus. You went to a destination just to get one thing done.

That era is ending.

The New Model: The App Comes to You

The next frontier of software isn’t about where users go — it’s about what they say.

You just ask for what you want.

“Book me a flight to Dubai next Thursday.”

And instead of getting a link to a travel site, the booking interface appears right inside your conversation.
No tabs. No downloads. Just intent → action → result.

This is the shift from Destinations (apps you open) to Moments (capabilities that appear exactly when you need them).

The Infrastructure Behind the Shift

This isn’t science fiction — it’s being built right now through OpenAI’s Apps SDK and the Model Context Protocol (MCP).
