Example: "stackoverflow or localhost:8081" would be "Development" kind of work. "news.ycombinator.com" --> "Reading" "gmail.com/outlook.com" --> "Commmunication" "facebook.com" -- "Unnecessary waste of time" ...and so on.
The reports would simply show- how much time I spent on what segment (Productive work/ General Browsing).
A chrome extension/app would be a good starting point - personally I do not use other browsers unless absolutely required.
Further I would also like it to automatically classify and show what kind of content I spend time browsing - like "Entrepreneurship / Programming / Nuclear fusion / Space Travel / ... "
If anybody wants to try it - let me know. I can dedicate a very small amount of time on this.
