SA (abbreviation of smart assistant) is a free and open source cross platform virtual assistant. It is built to run on Windows Linux and mac(yet to be tested). SA can open software, do Google and Wikipedia searches, search find word meanings and several other functions. It also has speech recognition facilities making it almost a fingerless interface.
For help in using it, watch: https://youtu.be/bLz6sER98u0

By just speaking "listen" you can bring the windows upwards, alternatively this can be achieved by clicking on the red cross button(this can also take the window down).In linux the same thing will fade the window in/out, after this you will see "listening" in one of the Labels.
And thats it,. you opened SA. Now you may try speaking open chrome or writing the same in the entry box, and next you may see the chrome window. In a similar way you can open any software.
Now you may type where is (some place), while typing you may observe some autocompletes, after pressing enter SA will show you some wikipedia extracts for the your search entry. You can also do this by speaking.
Similarly you can also search meaning of (some word) to find its meaning from wiktionary.
search (some thing) to see the google search extracts
The mic button starts the speech interface. Alternatively this can also be achieved by simply speaking listen while window is opened.
