Mark & Prompt: AI Image Edit Prompt Builder от Mansour Gilasgar

AI image editors often change the wrong area. Mark & Prompt helps you show exactly where each edit should happen before you send the image to an AI editor.

How it works
1. Right-click an image and choose "Open image in Mark & Prompt", or open, paste, or drag an image into the editor.
2. Draw numbered rectangles over the areas you want to edit.
3. Write one instruction for each marked region.
4. Add optional global instructions, such as preserving lighting, camera angle, style, or background.
5. Copy the generated prompt. It includes pixel coordinates, percentage coordinates, and plain-language locations.
6. Download or copy an annotated reference image with the numbered markers.
