Common questions about this Leonardo prompt builder.

The preset is the biggest single lever on how your image looks. Pick Photoreal for product shots and portraits that should look like real photos, Cinematic for dramatic, film-like scenes, Illustration for storybook and editorial art, 3D Render for game assets and product mockups, Fantasy Art for magical scenes, and Graphic Design Vector for flat logos and icons. The generator adds the preset to your prompt automatically.
Prompt Magic is Leonardo's prompt improver: it expands a short prompt with extra detail before generating, so thin prompts still produce rich images. It is great when your idea is rough, but turn it off when you want exact control over every word. The generator has a Prompt Magic checkbox so you can mark it in your prompt either way.
Alchemy is Leonardo's highest-quality generation pipeline — sharper detail, better lighting and cleaner textures than the standard pipeline. It costs more tokens per image, so save it for your final images rather than every test. The generator's Alchemy checkbox adds the quality note to your prompt.
A negative prompt tells Leonardo what to leave out — the classic list is no text, no blur, no distortion and no extra limbs. Leonardo has a dedicated negative-prompt box, so you do not have to squeeze the negatives into the main prompt. This generator adds a negative prompt line by default, and you can edit it to fit your image.
Leonardo lets you pick the aspect ratio and resolution, including square 1:1, widescreen 16:9, tall 9:16 and portrait 4:5. Square suits product shots and social posts, widescreen suits banners and landscapes, tall suits stories and phone wallpapers, and portrait 4:5 suits posters and feed posts. The generator adds the size to your prompt automatically.
Leonardo's terms allow commercial use of images you generate, with the exact rights depending on your plan — paid plans carry broader commercial rights than the free plan. The prompts on this page are free to use with no restrictions. Check Leonardo's current terms before using a generated image in a client project or an ad.
