PROMPTUARY is a free vault of AI image prompt formulas: the exact prompts behind real, published images, written for Nano Banana Pro, Seedream, GPT Image and the Seedance and Kling video engines. Every formula is a copy-paste recipe — camera, light, wardrobe and styling spelled out — shown next to the frame it produced, so you see the result before you generate. Ten subject categories, favourites, new drops as they land. Free account, no card; the free vault stays free.
