My first go program uses to help my children to learn orthograph.
It is very basic and ugly (well... it's my first go program...).
In addition, I hate HTML so the the HTML content is also ugly :p
It exposes a web server on port 8080 and ask you to upload a file with a list of word. Then it use the browser voice API to say the word, and you have to correctly write it. Right now, it only works with french word, but it can easily be changed by updating the javascript file located in www/js/golearn.js.
