XML Prompt Generator
The XML Prompt Generator structures your prompt and serialises it as XML — ideal for passing structured instructions to an AI or an API. Fill in the fields, pick a framework, and copy clean XML. Generated locally in your browser.
Fill in the fields to build your prompt…
When an AI's output has to be consumed by code, loose prose won't do — you need it serialised as XML. This generator structures your instruction and emits it as clean XML, so you can hand the model's response straight to a parser or an API.
How to use the XML Prompt Generator
- Fill in the task, role, context and constraints.
- Keep the output format set to XML.
- Copy the XML-formatted prompt into your AI or pipeline.
Common use cases
- Drive a function-calling or API workflow that expects XML.
- Get predictable, parseable output instead of free-form text.
- Define a strict XML schema the model should follow.
Tips
- XML tags cleanly delimit sections — handy for Claude and for nested data.
- Name tags meaningfully (<summary>, <steps>) so the structure is self-describing.
- State whether data should sit in attributes or child elements.
Frequently asked questions
Is anything sent to a server? +
No. The prompt is assembled entirely in your browser from your inputs — nothing is uploaded, and no AI API is called. It is a deterministic builder, so the same inputs always produce the same prompt.
Why ask the AI to reply in XML? +
When a model's output feeds code or an API, XML is parseable where free-form prose is not — you can hand the response straight to a parser.
Will the AI always return valid XML? +
Usually, if you state the schema clearly — but validate before parsing, since models can occasionally wrap the XML in prose or miss a field.
