## What it is
POML is a markup language from Microsoft for structuring, templating, and styling prompts for large language models, with an HTML-like syntax and CSS-like presentation styling. It ships with SDKs for Node.js and Python plus a VS Code extension providing syntax highlighting, autocomplete, and live previews.

## Use cases
- structure complex llm prompts in a maintainable markup format
- embed documents, tables, and images into prompts
- separate prompt content from formatting to reduce format sensitivity
- generate data-driven prompts with variables and conditionals
- edit and preview prompt files in vscode
- build llm applications with a prompt sdk

## When to choose
- you build sophisticated llm applications with large, reusable prompts
- you want tooling and editor support for prompt development
- you need to integrate external data files into prompts cleanly

## When to avoid
- you only write short one-off prompts where markup overhead isn't worth it
- your framework already handles prompt templating adequately
- you need a language with broad community adoption beyond microsoft's ecosystem
