Amazon has completely rebuilt Alexa from the ground up using modern generative AI. The “classic” Alexa you’ve known for years is being replaced by a much smarter version officially called Alexa+ (sometimes just called the “new Alexa”).

Google Home is a smart speaker similar to Amazon Echo. While Echo is powered by Amazon’s proprietary software and trigger word “Alexa”, Google Home’s software Google Assistant, is often referred to by its trigger phrase “Ok Google”.
