If you want to get into the trial for Adobe's Firefly AI image generator you will need to request access to the program. In jumping to this site you will need to fill out your information as well as how you think you're going to use the application. There is no cost involved in doing this. Videos that were shown on the site on using the application are very exciting and I can't wait to have access to Adobe Firefly product.
Two of the features that they are showing are text to image and text effects and they have videos that will demonstrate the use of them. This is not a finished product but a trial of a product in beta testing so they're going to ask you for some feedback. It does appear that you will have some Photoshop type capabilities. It looks like a lot of fun!
