What it does
Generates artwork with text or a shape concealed inside it: up close you see a landscape or pattern, but step back or squint and the hidden word emerges. You supply a description of the scene plus a high-contrast black-and-white image of what to hide. Thin lines and intricate lettering do not survive the process, so keep the hidden shape bold. The model's OpenRAIL++ licence allows commercial use but forbids certain applications.
Summary based on the project's own description. The Japanese page has a fuller beginner guide: setup difficulty, what to prepare, and a step-by-step start.

IllusionDiffusion FAQ
- Do I need to install anything or write code to use IllusionDiffusion?
- No install needed — it runs in the browser.
- Does IllusionDiffusion work on a phone?
- No. It needs a computer.
- Can I use IllusionDiffusion commercially?
- Only under conditions. The page shows OpenRAIL, but the actual terms — the AI model this page runs, or the provider's own terms — attach restrictions. Check the provider's terms before using it at work.
