What is the Claude prompt generator?

It turns a rough idea into a prompt written for Claude: one sentence of role, then XML tags: <context> for the material, <instructions> as numbered steps, <constraints> and <output_format>.

  1. 01Structured the way Claude reads

    XML-tagged context, instructions and output. For example, meeting notes go inside <context>, and <output_format> asks for a table of decisions, owners and deadlines.

  2. 02Placeholders instead of guesses

    Where the prompt needs a fact only you know, it leaves a placeholder in square brackets like [PRODUCT NAME] rather than inventing one.

  3. 03Good for long documents, reviews, code and any task where Claude must work from pasted material

    Start from one of the ideas under the text box or your own. Try for ChatGPT and Gemini rewrites the same prompt for another assistant.

  4. 04Open it in Claude

    Open in Claude starts a new chat with the prompt filled in. 10 free prompts a day without an account.

Claude prompt generator FAQ

How Claude prompts are built, what they cost and what happens to what you type.

1Why does Claude use XML tags?
Tags separate the material Claude should work from (a document, notes, code) from the instructions about what to do with it. Anthropic's own prompting guide recommends this structure, and long inputs get mixed up with instructions less often.
2Where do I paste my document?
Inside the <context> tags, where the prompt leaves a placeholder in square brackets. Open in Claude starts a new chat with the prompt filled in.
3How is this different from the general AI prompt generator?
It is the same tool with Claude chosen, so every prompt follows the Claude structure. Switch to ChatGPT, Gemini, DeepSeek and Grok or Any assistant in the menu under the text box.
4Can I change the prompt after it is written?
Use the buttons under the result: Shorter, More detail, Add an example or More formal rewrite the prompt you have, and Try for rewrites it for another tool. Each refinement counts as one prompt.
5Is it free?
Yes. You get 10 free prompts a day on each device without an account, and 20 a day with a free account. Paid plans remove the daily limit.
6Do you keep what I type?
Ideas and prompts written on this page are not saved to an account. They are sent to our AI model provider to write the prompt and are not shown to anyone else. Save keeps a copy in your own browser only.
