Part 1. What is AI Portrait?

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.

In the case of Wondershare UniConverter, you have nothing to worry about as everything is kept private on your PC.

Q2: How can I make a portrait online?

Simple, choose one of the website suggestions listed above. But it's vital to note that these apps are quite different in terms of functionality.

So, choose what works for you.

Q3: Are AI portraits free?

Yes, generating AI portraits is entirely free. If you search for "AI portraits app" on App Store or Play Store, you're likely to come across tens or even hundreds of free options. But be sure that most require paid subscriptions to unlock all portrait filters.
