Frequently asked questions

Does this tool use AI to write the prompt?

No. It assembles a structured prompt template from your inputs entirely in your browser — nothing is sent to any AI. You then paste the prompt into the assistant you want to use.

Why does prompt structure matter?

Giving an AI a clear role, audience, tone and output format reduces vague or off-target answers. A structured prompt is one of the simplest ways to get noticeably better results.

Which AI tools does it work with?

Any of them — ChatGPT, Claude, Gemini, Copilot and others. The prompt is plain text, so it's not tied to a specific model.
