There is no limit what kind of images can be generated from text using AI Illustwitter. The artwork can then be shared via AR-vatar and viewed in Augmented Reality.
In addition, you will enjoy the advanced AI-powered Image Editing features to named a few: Generative Fill, Generative Expand, Magic Move, AI Upscaler (upscale to 4X, 16X, and 64X to 8K 8192x8192 pixels images all in one go!), background remover, change background easily using text description and last but not least the magic AI Layering and automatic Repositioning in which intricate image is break down into separate layers and automatically reposition objects, transforming the way we approach image editing. AI Illustwitter is available to download from Apple Store and Google Play. Check it out!
