About this app

PixelDream turns a short idea into a picture — entirely on your phone.

Type a description of what you're imagining, and PixelDream paints it for you using on-device AI. No account to create, no images to upload, no internet required once you're set up. Your prompts and your pictures never leave your device unless you choose to share them.

WHY PEOPLE LIKE PIXELDREAM

🔒 Private by design
Image generation runs completely on your device. Nothing about what you type or create is uploaded as part of making an image.

✈️ Works anywhere
After a one-time setup download, PixelDream creates images with no Wi-Fi and no mobile data — on a plane, off the grid, wherever you are.

🎨 Genuinely simple
Describe what you're imagining and tap Create. An on-device AI can expand your idea into a richer prompt before a local image model renders it — no prompt-engineering experience needed.

🖼️ A gallery that's actually yours
Every image is saved to a private, local gallery. Revisit, export, or share anything you've made, on your own terms.

🎛️ You're in control
Choose generation quality and image size to balance detail against speed, and turn AI prompt enhancement on or off.

🛡️ Safety-minded
On-device checks run before and after prompt enhancement to steer away from harmful content, and an in-app report option lets you flag anything that gets through.

HOW IT WORKS

1. Describe your idea in a sentence or two.
2. PixelDream optionally expands it into a richer visual prompt, then a local diffusion model renders the image using your device's own hardware.
3. Your finished image lands in your private gallery — ready to view, export, or share whenever you choose.

WHAT YOU'LL NEED

• Android 10 (API 29) or newer
• An ARM64 device with 6 GB of RAM (8 GB+ recommended)
• About 5 GB of free storage for the one-time model download

The on-device models total roughly 4 GB and download once over Wi-Fi during setup. Older or lower-memory devices may run slowly or may not be supported.

A NOTE ON GENERATED CONTENT

PixelDream includes on-device checks that try to steer prompts and results away from harmful content, but no filter is perfect. Please use PixelDream responsibly, and use the in-app report option if something shouldn't have gotten through.

PixelDream includes optional ads and an optional ad-free upgrade. Some diagnostics and the optional in-app feedback/bug-report tool use the network; image generation itself does not. See the full privacy policy for details on exactly what each service can see.
