Perfect control, zero concept bleeding
Just fill in the fields - we handle the rest. Our visual editor automatically separates subject, face, style and background. No JSON knowledge required.
Concept bleeding destroys your results
With traditional prompts, attributes leak to wrong elements. Describe a 'red-haired woman in a green forest', and you often get a woman with a greenish tint or a forest with red accents.
"red-haired woman, in a wet rainforest, dramatic lighting"
Result: wet hair, wet skin, red tints in the forest, dramatic shadows everywhere - everything bleeds together.
"hair_color": "red"
"atmosphere": "green, natural"
Semantic separation prevents bleeding
The JSON Prompt Builder separates each aspect of your image into distinct slots. The AI knows exactly which attributes belong to which element.
-
Subject attributes stay with your subject
-
Background styling only affects the background
-
Lighting effects are correctly applied
Six roles for perfect control
Assign reference images to specific aspects of your generation. Each slot has its own purpose and prevents cross-contamination.
Subject
The main subject of your image. Use for transferring general features like body type, clothing or posture.
Face
Specifically for facial features. Keeps identity consistent across multiple generations.
Style
Determines the visual style. From photorealistic to anime, from vintage to modern.
Pose
Copy exact posture and body position from a reference image.
Background
Define the environment separately from your subject. Prevents background colors from affecting your subject.
Reference
General reference for composition, mood or other elements that don't fit in other roles.
Integrated with your libraries
Directly link your saved characters and source images to the appropriate image roles.
