On-device Stable Diffusion generation
Choose a curated model pack, write a prompt, and generate images on the iPhone itself instead of sending jobs to a cloud service.
Overview
PhoneDiffusion is a local AI image generator for iPhone built around Stable Diffusion. It lets users create images on-device with curated model packs, rather than routing prompts and renders through a cloud queue.
The product is positioned around privacy and offline use: after the app and model are downloaded, generation can continue without internet access, and the site says prompts, generated images, and history stay on the iPhone. The homepage also notes support for curated Stable Diffusion 1.5 and SDXL model packs on supported devices.
What PhoneDiffusion does
Offline workflow after setup
The app is designed for use after the first model download, so image generation can continue without internet access.
Local storage for prompts and results
PhoneDiffusion says prompts, generated images, and history stay on the device, which keeps the workflow private by default.
Device-aware model selection
The homepage references curated model packs for SD 1.5 and SDXL, with the app selecting a launch model that fits the device.
Save to Photos on demand
The site says Photos permission is requested only at save time, so users can keep generation separate from their photo library until they export an image.
Common ways to use PhoneDiffusion
Private image creation on the go
Use PhoneDiffusion when you want to generate AI images on a phone without sending prompts or outputs to a cloud service.
Offline generation after setup
After downloading the app and model pack once, continue creating images in places where you do not have reliable internet access.
Testing Stable Diffusion on-device
Pick a curated model pack and create with the device-aware setup that the site describes for supported iPhones.
Local drafting and selective saving
Save only the images you want to keep in Photos, while leaving the rest of the generation history stored locally on the phone.
Accountless mobile workflow
Use the app when you want a mobile Stable Diffusion workflow that does not rely on accounts or per-image credits.
