How to Build Apps using App Builder in Microsoft 365 Copilot

The App Builder tool in Microsoft 365 Copilot is fundamentally altering how apps are built, enabling rapid transformation from concept to reality at a pace never seen before. The ability to pass a prompt and have everything ready feels surprisingly simple. But this is precisely what application development has been all about, but it required coding skills and a long development time.

Picture this: you describe your idea in a few words, and within minutes, the app is up and running. The new approach enables everyone to build, test, and share apps without getting caught up in technical confusion.

Quick Answer:

To build an application with Microsoft 365 Copilot, navigate to App Builder (Frontier) and write a prompt. Allow Copilot to create the app, adjust it with prompts, preview it, and share it seamlessly.

What is Microsoft 365 Copilot App Builder

The App Builder feature in Microsoft 365 Copilot lets you create apps just by typing commands or requests. You don’t code. You provide a prompt, and then the app builds itself.

It is part of the Frontier program, which develops early- and advanced-level AI features. This is why the App Builder (Frontier) has a faster, more experimental feel, making it easy to turn ideas into apps.

Note: 

The Frontier program is an early-access initiative by Microsoft that introduces new and experimental AI features before full release.
