 Data Selfie basically tracks the things you like and view, how long you stay at them, what you click, and what you search for & applies the powerful IBM Watson cognitive algorithm to process this data.

When you download and install Data Selfie in your browser, the app starts monitoring your Facebook activities. It creepily tracks the posts that you ‘like’, the posts on which you spend the most time whether it’s a post from a friend or a liked page. Every single fragment of activity data gets logged and processed through the Watson AI. More creepy is that it starts giving predictive analysis by guessing things about you including your shopping needs, nutrient preferences, and political interests.  

The Chrome plugin has an interactive dashboard to show the data collected and processed by machine learning algorithm. The data is broken down in various color stats to make it easy to focus on more important data.
