5. Adobe Firefly

Adobe Firefly Image 2 is an interesting beast. For one, the web-based application has a fully free plan that offers 25 credits every month. That’s pretty good compared to other services online. Two, it uses the company’s AI model that only uses images from its stock site, for better or worse.
The actual outputs feel very basic in that way. Turning it to the “art” content type leads to a very ad-friendly kind of output. It’s not enough to wow your friends, but the site itself offers a fair bit so long as you sign up for Adobe’s site.
