What is the use of Xiaona in the Win10 Spartan browser?

So the question is, what is the use of the Cortana assistant in the Spartan browser? The answer is that it is useless at this stage.
Foreign media mentioned in the report that since the application of Cortana's assistant in the Web field is still in its infancy, even the Spartan browser has not yet finalized, so most websites do not support the Cortana assistant function. This means that "Xiao Na" is only a display.
But there are exceptions. The restaurant titled Cuoco-Seattle provides the Cortana assistant function. When the user visits the page, Cortana will list the restaurant's location, menu, business hours and other useful information on the right side of the screen.
According to the plan, Windows 10 will be officially launched this summer. I hope that more websites will introduce Cortana assistant functions to facilitate the life and travel of users.
