What Is Inpainting?

Inpainting is like painting on top of an image with the help of AI. First, you choose the area of the image you want to change. Then, you give the AI a prompt of what you want to appear in that area.

For example, you might say, “Change this shirt into a black evening gown,” or “Add sunglasses to this face.”
