Use your webcam to monitor your facial expressions while you browse the internet.

Blissify uses face tracking technology to automatically block the websites that make you unhappy.

Blissify is an extension for Google Chrome.

The first time you launch Blissify you will be asked to do a quick calibration: this is so that Blissify knows what your 'neutral browsing expression', or NBE, looks like. You will be shown a picture of your face and the person who will be looking after you as you browse the web.

How does Blissify work?

To get started, open Blissify and select the 'I' tab. From there, select the 'Block' tab and you're ready to start browsing the internet.

All you have to do is tap the button that will take you to the 'Settings' tab. From there, you will be able to adjust the level of negativity.
