let me know some technical specification of it

Okay, it's made with Microsoft Visual Studio 2017. I programmed it in C# with DotNet version 4.5.2, and Javascript embedded into the application using a browser control called CefSharp. CefSharp is essentially the Chrome browser made for embedding into software, it's rather large and I think that's why the source code is such a long download.
Steem Office is basically two programs made to work together, one is the javascript interface, and the other is the C# program that loads the javascript interface. The C# part manages the log in credentials and if the user chooses to save the login to their hard drive it encrypts the login information twice, once with a password and again with a key file that it generates in real-time for extra security.
The javascript part of Steem Office is where it starts looking like a word processor. The javascript code is based on my earlier work, http://PortableSteem.com, but I modified it to work with the c# part. The javascript loads some external 3rd party libraries like SimpleMDE for the text editor, and Steem JS to connect with the Steem Blockchain.
Steem Office is currently only running on 64-bit Windows PCs, but it might also be able to run on Mac OS X and Linux computers with the Mono Framework installed (https://www.mono-project.com). Also, since most of the program is written in Javascript it could be made into an Android or IOS app by wrapping the javascript code into a native program, just like how it was embedded into C#.
