The first project, Avolo, is an all-purpose offline text-to-image AI client that can generate images without any subscription limits. It's got features like AI upscaling for large images, texture mode for patterns, and a prompt enhancer to refine short prompts. Avolo is available for both Apple Silicon and Intel, so you should be able to run it and get it to render fast on Apple M1/M2 chips.
If you want a free and versatile AI art generator, check out Artimator. It uses multiple AI models to generate images in different styles, and it's got features like multi-art style transformation, hyper-detailed generation, and the ability to turn photos into anime, cartoon or cyberpunk. It's got unlimited free image generation, but you can pay once for premium features.
