How it works

What is the Claude Prompt Generator?

The Claude Prompt Generator is a free tool that turns a task description into a ready-to-use prompt for Anthropic's Claude. It comes with a role, the task, constraints and an output format, and you choose whether it comes wrapped in XML tags, as Anthropic recommends for long prompts, or as plain prose.

How to use the Claude Prompt Generator

Describe what you want Claude to do in the first box, such as "Write a launch email for a technical SEO product".
Add the audience, tone, constraints and anything Claude must not say in Context. It is optional, but it is what makes the prompt reusable.
Choose XML tags or Plain text under Structure, then press Generate prompt.
Copy the prompt from the result panel, or press Open in Claude. The first time, sign up free to reveal the result.

Why use XML tags in Claude prompts?

Anthropic's prompting guidance recommends XML tags to separate the parts of a prompt: instructions, context, examples, input data and output format. Tags stop Claude mixing up your instructions with your material, and let you point at a part by name, as in "using the report in <report> tags".

No tag names are special. Claude was not trained on a fixed set, so pick names that describe their contents and use them consistently. A short prompt reads fine as prose. Tags pay off when one prompt carries reference material, rules and a required format together.

What does the generated Claude prompt contain?

It is written to give Claude a role, the task, the constraints it has to respect and the shape of the answer you want back. The answer format is the part people skip, and it is why two runs of the same prompt come back looking nothing alike.

It also tells Claude what to do when information is missing. Left unsaid, a model fills the gap quietly, and you cannot tell the invented part from the answer.

Does the prompt go in the system prompt or the user message?

Split it. On the API, Claude's role and standing rules go in the system parameter, and the task and the material you want worked on go in the user message. In the Claude app there is no system field, so paste the prompt as the first message, or save the standing part as a Project's instructions and send only the task.

Keep your input apart from the instructions either way. Pasted together as one block, Claude has to guess which lines are orders and which are data, which is the confusion tags exist to prevent.
