Why each AI gets a different prompt

ChatGPT follows clearly labelled Markdown sections. Putting the role, task, context, constraints and output format under their own headings makes instructions hard to miss and easy to edit.

Every prompt is built from the same modular parts — role, task, context (your audience and details) and output format — then rendered in the style each AI follows best. Change the AI in the drop-down and the same request is rewritten instantly.

ChatGPT prompting tips

  • Paste the whole prompt as one message — ChatGPT follows Markdown headings closely.
  • For long or high-stakes work, choose a reasoning (Thinking) model in the model picker.
  • Save the Role section as Custom Instructions or Project instructions to reuse it.

Ready-made prompt types

Choose a prompt type for your task; each comes with an expert role, context rules and an output format:

  • Write anything — for example “a blog post about the benefits of remote work”.
  • Summarise & analyse — for example “the meeting transcript I'll paste below”.
  • Brainstorm ideas — for example “20 names and taglines for a new coffee subscription brand”.

Frequently asked questions

What is an AI prompt generator?
It turns a plain-language request into a structured prompt — role, task, context and output format — written the way each AI follows best, so you get better answers on the first try.
Does this tool send my text to an AI?
No. The prompt is assembled in your browser from templates. Nothing you type is sent to any server or AI until you paste it yourself.
Why does the prompt change when I switch AI?
Models are trained on different conventions: Claude responds well to XML tags, Gemini to Persona/Task/Context/Format, Midjourney to descriptors and --parameters, Suno to style tags and a lyric sheet. The generator rewrites the same request for each.
What if I leave a field empty?
The example shown in grey is used instead, so the prompt is always complete. Replace it with your own details for the best results.
Is the prompt generator free?
Yes — free, unlimited and no account needed.
