Alexa is the brain.
Alexa is a cloud-based voice service that can help you with tasks, entertainment, general information, and more. Alexa is always getting smarter, with updates delivered automatically and more functionality added over time. The more you talk to Alexa, the more Alexa adapts to your speech patterns, vocabulary, and personal preferences. Alexa gives Amazon Echo and other devices the power of hands-free voice control.
Using Alexa is as simple as asking a question. Just ask to play music, read the news, control your smart home, tell a joke, and more-Alexa will respond instantly. Whether you're at home or on the go, Alexa is designed to make your life easier by letting you voice control your world.
