This ComfyUI workflow is designed to enable users to seamlessly swap a product in a character's hand within an image, making it particularly useful for user-generated content (UGC) and marketing applications. By utilizing the Gemini3 Pro Image Preview model, the workflow ensures high-quality image processing tailored for product replacement tasks. The process begins with the LoadImage node, which allows users to upload both the original image of a character holding a product and the image of the brand's product intended for replacement. The core of the workflow is the GeminiImage2Node, which intelligently analyzes the images to identify the product in the character's hand and swap it with the new product while maintaining the natural look and feel of the original image. Finally, the SaveImage node ensures that the modified image is saved for further use or distribution. This workflow is particularly useful for brands looking to quickly generate marketing materials that feature their products in diverse settings without the need for extensive photo shoots.
