How the Leonardo AI prompt is structured
Leonardo AI understands full sentences, so the prompt reads like a photographer's brief: subject, setting, lighting, composition, mood and where the image will be used.
Every prompt is built from the same modular parts — role, task, context (your audience and details) and output format — then rendered in the style each AI follows best. Change the AI in the drop-down and the same request is rewritten instantly.

Frequently asked questions
What is a Leonardo AI prompt generator?
It turns a plain-language request into a structured prompt — role, task, context and output format — written the way Leonardo AI follows best, so you get better answers on the first try.
Does this tool send my text to Leonardo AI?
No. The prompt is assembled in your browser from templates. Nothing you type is sent to any server or AI until you paste it yourself.
Why does the prompt change when I switch AI?
Models are trained on different conventions: Claude responds well to XML tags, Gemini to Persona/Task/Context/Format, Midjourney to descriptors and --parameters, Suno to style tags and a lyric sheet. The generator rewrites the same request for each.
What if I leave a field empty?
The example shown in grey is used instead, so the prompt is always complete. Replace it with your own details for the best results.
Is the prompt generator free?
Yes — free, unlimited and no account needed.
