Frequently asked questions

Does this prompt generator call an AI service?

No. It assembles the prompt locally from the fields you provide; nothing is uploaded and no API key is required.

Which AI tools can I use the prompt with?

The output is plain text or Markdown and works with ChatGPT, Claude, Gemini, image generators and other instruction-following AI tools.

What makes a prompt more useful?

State the task, provide relevant context, name the audience, specify the output format and add constraints. Concrete examples also reduce ambiguity.
