How to Use the ChatGPT Prompt Generator

  1. Describe the task in one line, for example “Write a follow-up email to a client who hasn’t paid”.
  2. Pick a category, tone and output format, or leave them on automatic.
  3. Generate the prompt and check the completeness score for anything missing.
  4. Copy it into ChatGPT. Fill in any bracketed placeholders with your own details first.

What makes a ChatGPT prompt work

  • Give it a role

    “You are an experienced bookkeeper” sets the vocabulary and the level of detail. The generator adds a role that fits your category.

  • Add the context only you know

    Your business, your audience and what you have already tried. ChatGPT cannot guess these, and they matter more than clever wording.

  • Ask for a format

    A table, five bullet points, or an email under 150 words. A clear format makes the answer easier to use straight away.

  • Say what to avoid

    Jargon, made-up statistics, a too-salesy tone. Constraints stop the answers you would otherwise have to rewrite.
