Amazon Alexa is the companion app for Amazon's Alexa voice assistant, developed by Amazon.com, Inc., a company founded in 1994 and headquartered in Seattle, Washington. It manages Echo speakers and displays, Fire TV devices, and thousands of third-party smart home products and Alexa "Skills."
The app lets users set up and group Echo and compatible smart home devices, view and control cameras, lights, plugs, thermostats, and locks, create multi-step Routines triggered by voice, schedule, or device state, and manage shopping lists, reminders, timers, and music playback. Alexa+, Amazon's generative-AI upgrade to Alexa, adds more conversational, context-aware responses and the ability to complete multi-step tasks like booking reservations. The Skills store extends Alexa's abilities with add-ons from third-party developers.
Alexa is aimed at households using Echo devices or other Alexa-enabled hardware for voice control of music, information, shopping, and smart home devices, from a single speaker to whole-home automation setups spanning multiple brands.
The app is available on iOS, Android, and the web. It is free to download; the underlying service is free with purchase of Alexa-enabled hardware, while Alexa+ is included free with a Prime membership or available as a standalone subscription for non-Prime members.
