Amazon Alexa, or simply Alexa, is a virtual assistant technology marketed by Amazon and implemented in software applications for smart phones, tablets, wireless smart speakers, and other electronic appliances and at Alexa.com.

Alexa was largely developed from the British computer scientist William Tunstall-Pedoe's Evi system and a Polish speech synthesizer named Ivona, acquired by Amazon in 2012 and 2013. From 2023 to 2025, Amazon shifted to an in-house large language model named Nova to be used in a new generation of Alexa, called Alexa+, that occasionally used Anthropic's Claude model.
