Describe your subject and pick a style, and get a descriptive prompt ready for Leonardo AI’s generation tools.
What Is a Leonardo AI Prompt Builder?
A Leonardo AI prompt builder turns your idea into a descriptive prompt ready to paste into Leonardo AI’s generation interface. Leonardo AI handles model choice, style presets, and image settings through its own UI, so this tool focuses on writing a strong descriptive prompt to pair with those settings.
The tool above is free, runs entirely in your browser, and doesn’t send your input anywhere.
How to Use This Free Leonardo AI Prompt Builder
- Describe what you want to see.
- Pick a style.
- Click “Build Leonardo AI Prompt,” then paste it in, and choose your model and settings in Leonardo AI’s own interface.
Prompt Text vs. Interface Settings
Unlike Midjourney, which uses text-based flags like --ar inside the prompt itself, Leonardo
AI’s model selection, style presets, and generation settings live in its dashboard controls. Pair a good
descriptive prompt with the right presets for your use case rather than trying to encode settings into
the text.
