What Is the Alexa Skills Kit? 

The Alexa Skills Kit (ASK) is a collection of self-service APIs, tools, documentation, and code samples that makes it easier to start building Alexa skills. Skills are like apps for Alexa, enabling customers to perform everyday tasks or engage with your content naturally with voice.

Join hundreds of thousands of developers who are building Alexa skills to engage and delight customers on more than 100 million Alexa-enabled devices.
