From a one-line idea to a detailed direction

System Prompt Maker only needs a sentence or two about what you want. It expands the idea into detailed instructions under headings like identity, style, light and camera, then renders an image and a video in that direction.

How it works

GPT-5 mini writes rules that translate your idea into visual language. Nano Banana renders an image from them, and you can add a note. A video script comes from the same rules, and Seedance 2.0 renders the video with the image as reference.
