An online demo for image editing: upload an image and use natural language prompts together with brush masks to add, remove, modify, or expand content. It supports both English and Chinese instructions. Useful for quickly testing instruction-based image editing workflows, comparing models, or giving non-technical teammates an easy demo. Possible discussion topics: where prompt-based editing fits into real-world workflows, how it complements traditional Photoshop/retouching tools, and the trade-offs between fine-grained control and convenience.
