There are three major features of the app. The first is the ability to create and then hone an image from a simple text prompt. To better edit an image creation, Generative Fill can be used to add new content, replace the background, or even remove unwanted elements. 

The app also features an AI-generated video creator and video editing. Just like with images, you can create a video with a text prompt. You can select from different resolutions and aspect ratios to best meet your vision. 

It’s also possible to convert an AI-generated image into video with motion and cinematic transitions. 

You can also edit AI video to remove distractions, improve colors, and adjust specific details. To guide a composition, you can also upload a video. 

All of your creations are synced with your Creative Cloud account. 

The Firefly app is a free download now on the iPhone. Some AI tools will require a monthly or yearly subscription of $4.99 or $49.99 respectively.
