This is Prashant , Co Founder of Shifu . Thanks Guys for hunting . @aditya : We do it by algorithmically analysing your usage pattern and predicting what you are most likely to do next . for example we look at your calling pattern based on time of the day(morning ,noon ,night ),day of the week(weekday /weekend), Location( Home/office, SF ,Delhi ) , activity( driving etc ) and learn what were your action in similar context and predict next thing you are likely to do . its a mix of art and science . would love to know your feedback about how good a job we are doing.
