Describe it with AI

Write one sentence. Get a wallpaper you can still edit.

No prompt engineering. Name a place, a mood or a colour, and the AI art director turns it into a wallpaper in a few seconds.

Or try one of these

  • You get settings, not a flat image

    The AI chooses an engine, palette and parameters. Your browser draws the result, so it stays sharp at 8K and every slider still works.

  • Only your words leave the browser

    The description goes to an AI provider (Groq, or Google Gemini as a backup) to pick a style. Rendering and downloads happen on your device.

  • Never stuck

    If the free daily AI allowance runs out, Wallogen builds a close match from your words on-device instead.

How it works

Three steps from idea to wallpaper.

Nothing is downloaded from a library. Each wallpaper is drawn from code the moment you ask for it, so it is sharp at any size.

  1. 01

    Pick an engine or describe a scene

    Choose from 18 engines such as Ocean Waves, Aurora, Origami Peaks and Frosted Glass, or type "red house at dusk" and the AI picks the pattern, colours and settings for you.

  2. 02

    Tune it live

    Change the seed, scale, density, rotation and grain, or swap between 13 curated palettes. Every change re-renders instantly in your browser.

  3. 03

    Download at your exact resolution

    Exports are rendered again from the math at full size: 3840×2160 for 4K, 5120×1440 for ultrawide, 1290×2796 for iPhone, or any custom size up to 8K.

FAQ

Price, privacy, resolution and licensing.

Yes! Wallogen is 100% free and open for everyone. There are no paywalls, accounts, or watermarks. If you enjoy the wallpapers, you can voluntarily buy the creator a coffee!
When you click "Download Wallpaper", Wallogen creates an offscreen canvas at your exact requested target resolution (e.g. 3840×2160 for 4K Desktop or 1290×2796 for iPhone). It re-renders the procedural vector math natively at full resolution so the image is crisp down to the pixel.
No. All rendering and export logic happens 100% client-side directly inside your web browser. Your wallpapers and images are never uploaded anywhere.
When you type a description, only that text is sent to an AI provider (Groq, with Google's Gemini as a backup), which picks a pattern, colors, and settings. Your browser then renders the wallpaper locally, so it stays sharp at 4K and 8K and you can keep tweaking it. We use these providers' free tiers, where they may use prompts to improve their products, so please don't include personal information. If the free daily AI allowance runs out, Wallogen makes a close match from your words on-device instead.
Absolutely! You are free to use any wallpapers you generate for personal desktops, mobile phones, video streams, or commercial media projects.

Support

Free, with no ads. A coffee keeps it that way.

Wallogen is built and paid for by one person. If it gave your desktop a new look, a coffee covers the AI costs and funds the next engine.
