What is PhoneDiffusion?
PhoneDiffusion is an AI image generation tool that runs Stable Diffusion locally on iPhone, letting you create images on-device without a cloud workflow. Instead of sending prompts to a server, the app downloads curated Stable Diffusion 1.5 and SDXL model packs and generates images directly on supported devices, so prompts, outputs, and history stay in a private local gallery. It routes each phone to a curated launch model (SD 1.5 or SDXL) based on device capability, and works offline after the initial setup and model download. There is no account or credit system required to start generating. The Pro tier adds premium curated models plus manual controls for CFG scale, step count, and batch size, giving users finer control over image quality and output volume. Photos access is only requested when you explicitly save an image, keeping permissions minimal. PhoneDiffusion is aimed at creators, hobbyists, and privacy-conscious users who want on-device AI art rather than one-click cloud generators. Pricing follows a free-tier plus Pro model; a specific Pro price is not published on the homepage.
