Platform Optimized
Generate prompts tailored for Midjourney, Stable Diffusion, DALL-E, or Flux — each with platform-specific syntax and best practices.
Style Transfer
Recreate any image in a different art style — oil painting, watercolor, cyberpunk, anime, Studio Ghibli, pixel art, and more.
Multi-Angle Views
Generate 5 prompts from different viewpoints — front, three-quarter, side profile, back, and bird's eye — while preserving the same subject and scene.
Portrait: Pose Variants
Generate 5 dramatically different poses, camera angles, and expressions of the same person — clothing and identity stay locked.
Portrait: Character Replace
Generate a scene prompt with a character placeholder — fill in your own character description and upload your reference photo to recreate the scene with a different person.
Portrait: Char + Pose Variants
Combine character replacement with pose variation — get 5 dramatically different poses, each with a character placeholder ready for your own reference photo.
Structured JSON
Get a structured JSON prompt with editable fields for subject, clothing, lighting, background, vibe, and more — perfect for fine-grained control and programmatic workflows.
NyxTemplate Export
Distill an image's visual style into a reusable .nyxtemplate file — the subject becomes 3-6 editable variables while lighting, palette, composition, and mood stay locked. Download and import straight into NyxAstra Gallery.
