After logging in with an Amazon account, you can start asking Alexa questions by clicking and holding on the mic button.
Alexa is capable of answering basic questions around information, weather, news and music and control other gadgets in the home. But since launch, one of the real differentiators for the Echo has been integration with third-party developers.
An Amazon Echo can help you use your voice to order anything from a pizza to an Uber or even tune your guitar.
But the problem is that majority of people who don't own an Echo have no opportunity to play around with the device and see how it works. The Echosim.io is built by Nexmo developer advocate Sam Machin.
Amazon's plan is to turn Alexa into a platform that stretches past Amazon's own hardware. SDKs and APIs were recently launched by the company so that both hardware and software developers could integrate Alexa into their wares.
