If you run Windows 10, you can have her! More powerful than Windows’ Cortana, you can have her run on your PC now. Just say “Alexa” and start speaking.
You will have to give permissions to your microphone. You will also have to sign in with your Amazon account. Alexa will listen in the background and you can access it just like Amazon Echo.
So what happens if you have the Alexa app on a Kindle, an Amazon Echo, and you put this on your PC? Well, we wondered too and found this on Amazon.com Basically it says the closest one will respond. Some content and settings are shared but not all. While it may not work the way you intend or is different than the Echo device, it may be helpful.
