In this 21st century, AI (Artificial Intelligence) is arguably the most innovative technology around. It uses computer programming and science to generate automated systems. In return, this greatly saves time and effort. Good examples of how we use AI in our lives are Google Assistant, Apple Siri, and Amazon Alexa.

But what exactly are AI portraits? These are imaging techniques used by computers and smartphones to blur or erase image/video backgrounds automatically. An AI portrait generator automatically figures out the main subject in the video before blurring the background. Put simply, such apps can remove the background without necessarily needing a chroma key or green screen. Let's continue discussing this in the next section.
