What it does
Instead of writing a prompt from scratch, you choose from lists - composition, lighting, art style, camera type - and it assembles the detailed English prompt for you, which is a fast way to acquire the vocabulary these models respond to. The result pastes into any generator. More detail is not automatically better: overloading the prompt dilutes each instruction, so start with a few choices and add only what is missing.
