The starryai app is an AI image generator developed for Android and iOS. The app is free but you do need to create an account, and the monetization model means they run ads within the app which can be rather annoying but understandable. This image generator uses two AI models to generate art. First one being, Altair, which uses VQGAN-CLIP model to render the artwork creations. The second is, Orion, which uses CLIP-Guided Diffusion to create stunning artworks and imageries.
