In this rising phase of technology, the artificial intelligence has taken over the place to satisfy human calls and needs. There are four major players (AI assistant) competing for the best: Amazon (Alexa), Apple (Siri), Google (Google Assistant) and Microsoft (Cortana).
Here below we will have specific details of each of the above four AI assistants to know which is the best amongst all.
Amazon's smart assistant is available through the Amazon Echo line of speakers as well as through Amazon's line of tablets and Fire TV. There is also an Alexa app, but the app is aimed primarily as a continuation of another Alexa device and not as a stand-alone AI assistant.
You can access Siri on nearly any Apple device, including its line of laptops, desktops, phones and tablets. Siri is also presently handy via the iPod Touch, and it is available on the Home Pod after it released in December 2017.
Google Assistant is obtainable on all Android and iOS devices as well as on Chromebooks. Google has its own line of Google Home speakers that are built for use with Google Assistant, but it's also accessible on many third-party smart home speakers.
Microsoft's AI, Cortana, comes typical on Windows machines, but it's also available for download on Android and iOS.
So, now since the choices are briefly explained above, you decide which AI assistant is the best amongst all.
