Don't Change Studio — Face Lock AI Prompts | NanoPrompts
Upload any photo, reuse a reference face description, then change only exactly what you want. Our Don't Change Studio gives you precise control — change only the pose while face, clothing, background and everything else stays identical, or change only the outfit while pose, face and background remain the same. Available for girl, boy and couple subjects.
The Don't Change Studio is powered by Gemini Vision AI that automatically analyzes your uploaded photo and extracts a detailed face description covering eyes shape and color, nose structure, lip shape and fullness, jawline, skin tone using Fitzpatrick scale, any distinctive moles or freckles, eyebrow shape and thickness. This face description is then embedded at the start of every generated prompt encouraging identity consistency without guaranteeing identical images. With 13 change element categories including pose, clothes, background, hairstyle, makeup, jewelry, mood, lighting, camera angle, season, props, accessories and cultural outfits — each with 30 to 50 options — you have complete creative control.
