Sift is a multipurpose bot which can understand your natural language queries and respond quickly. It is created with the objective to enhance messaging with friends and to get quick information without leaving the messaging app you are in.
It understands natural language so ask it anything and it will give you the thing you want. No need to remember any command and pattern just ask however you like.
God forbid if it unable to understand or didn't get the required information you are looking for, even then you don't have to worry. Sift keep learning whenever it fails, in the background it will learn your query and will available for you that question next time.
So, I think I already praised it very much, now you just start it and try it yourself and see why I am bragging about Sift so much.
