About Amazing AI
Amazing AI is a free, native macOS, iOS, and visionOS app that generates images from text descriptions using Stable Diffusion 1.5. It runs entirely on-device via the Apple Neural Engine, keeping your data private and enabling offline use. The app is designed for simplicity: no custom models, no inpainting, and only square outputs. To get good results, you must craft detailed prompts; negative prompts are supported using "##" as a separator. Generated images include metadata (prompt, steps) and can be previewed with keyboard shortcuts. Batch generation of different prompts, automatic upscaling, and Shortcuts integration are built-in. Hardware requirements are strict: Apple Silicon Mac (M1+), iPhone 15 Pro+, or iPad with M1. The app is free on the App Store with no ads or in-app purchases; a non-App Store version is available for supporters. Sindre Sorhus also offers Imago, which uses Flux 2 for a more modern model. Compared to DiffusionBee, Amazing AI is faster and more energy-efficient thanks to the Apple Neural Engine, has a native UI, and supports batch generation of different prompts, but lacks inpainting, outpainting, image-to-image, and custom model support. It's ideal for casual creators and privacy-conscious users who want a no-fuss, offline image generator on Apple devices.
Behind the Verdict
Amazing AI is a showcase of what Apple Silicon can do. Running Stable Diffusion 1.5 entirely on the Neural Engine is a technical feat, and the app is genuinely fast and responsive on supported hardware. The developer's choice to keep it free, ad-free, and focused reflects a clear philosophy: simplicity over features. If you're on an M1 Mac or an iPhone 15 Pro and just want to generate a few images from text without dealing with model downloads, compromise, or cloud subscriptions, this app is perfect. That said, Stable Diffusion 1.5 is now several generations old. Models like Flux or SDXL produce far better results with less prompt engineering. The fixed square output is also limiting. If you need modern capabilities, Sindre Sorhus's other app, Imago (uses Flux 2), is a better choice — though it may not be free. The FAQ openly acknowledges the app's limitations and points you to alternative tools for more advanced use cases. That honesty is refreshing. Where it bites: the hardware wall is severe — no Intel Mac support, no iPhones before 15 Pro. If your device is even slightly older, you can't run it. And the one-model-only approach means you won't grow with the app. We'd reach for Amazing AI when we need a quick, private, offline test of a prompt idea. For anything more, we'd look elsewhere.
