What you can do

Generate, edit, refine, ship

Text to image

Describe what you want in plain English. Pick a model, hit generate, see results in seconds. Use the Magic Prompt enhancer to turn rough ideas into production-grade prompts automatically.

Image to image (img2img)

Upload a reference photo and transform style, lighting, or subject while preserving composition. Works on Gemini and Flux. Use up to five reference images per prompt with @image1, @image2 tags.

Inpainting

Brush over any region and regenerate just that area. Replace backgrounds, swap products, fix hands and text, all without re-rolling the rest of the image.

Outpainting

Expand any image beyond its original frame. Turn a square portrait into a 16:9 banner or a vertical poster, with the AI continuing scene context naturally.

Style presets and negatives

13 production-tested style presets (cinematic, editorial, product photography, neon noir, etc.) plus 6 negative-prompt presets that suppress common AI artifacts in one click.

Seed control and batch

Lock a Flux seed to reproduce a look across variations, or batch generate dozens of variants in parallel. SSE streaming surfaces each image as it finishes.
