Cortana vs. Siri vs. Alexa vs. Google Assistant: The Best AI

Alexa

Amazon.com, Inc. (NASDAQ:AMZN)’s response to the budding AI assistant wars is unique compared with its tech rivals. The online retailing behemoth launched Alexa in 2015 as a main feature of the home-based Echo and Echo Dot speakers it was selling. A user can tell the Echo speaker its question or command, and Alexa will respond accordingly. The tech community gave rave reviews for Alexa when it debuted, praising the AI assistant for setting a high bar for smart home AI technology, while also showcasing convenient ways for people to order on Amazon. However, Alexa’s residence in speakers prevents it from providing visual answers. To address that problem, Amazon introduced the AI assistant on Amazon tablets.
