The 6-section framework

Every refined prompt is built from the same six parts.

  • Role

    Who the AI should act as, and with what expertise.

  • Task

    The specific outcome you want produced.

  • Context

    Background details the AI needs to get it right.

  • Reasoning

    How the AI should think before answering.

  • Stopping conditions

    When the AI should ask, stop, or flag uncertainty.

  • Output format

    Exactly how the result should be structured.

Frequently asked questions

What does AI Prompt Online do?
You paste a rough prompt and it comes back restructured into six sections — Role, Task, Context, Reasoning, Stopping Conditions, and Output Format — ready to paste into any AI model.
Is it free?
Yes. You get 5 refinements a day with no account — just paste and go.
What happens when I hit the daily limit?
You'll see a message when your 5 free refinements reset at midnight. Pro removes the limit entirely.
What do I get with Pro?
Unlimited refinements, unlimited saved prompts, and public share links you can send to anyone.
Which languages are supported?
English, Portuguese (Brazil), and Spanish (Latin America) — the whole site and refiner work in all three.
What AI model powers the refiner?
Claude, from Anthropic. The model can change over time as better versions become available.
Is my prompt data stored or shared?
Refinements aren't stored unless you sign in and save them. Saved prompts are private by default — you choose if and when to create a public share link.
Do I need an account to use it?
No. Refining and copying is free with no sign-in. An account only adds saving and sharing.

Your next prompt deserves better structure.
