Using The Microsoft Bot Framework Composer

You can visually create Bots using the Microsoft Bot Framework Composer.

The Microsoft Bot Framework Composer is a GitHub project that you download and run locally.

image

Bots are created by defining intents

Intents can be mapped to dialogs that you can visually design.

You can launch the the Bot Framework Emulator from the application.
