In embodiments, an electronic device is provided. The electronic device may comprise: a display; a processor including a processing circuit; and a memory for storing instructions. The instructions, when executed individually or collectively by the processor, cause the electronic device to: identify a primary object of an input image and one or more secondary objects associated with the primary object; generate candidate prompt portions for the primary object and the one or more secondary objects using an artificial intelligence (AI) model; present the candidate prompt portions and the input image through the display; generate a prompt to modify the primary object based on a user input received for a candidate prompt portion of the candidate prompt portions; and generate an output image by providing the image modification prompt to an image AI model. The candidate prompt portions may correspond to respective editable objects in the input image.
