## What it is
A Markdown viewer and exporter available as a browser extension (Chrome, Edge, Firefox) plus Obsidian and VS Code plugins, with a Node.js headless-Chrome CLI. It renders Markdown with themes, math, and diagrams (Mermaid, Graphviz, Vega, drawio) and exports to DOCX, PDF, and self-contained HTML with all processing done locally.

## Use cases
- preview markdown files in the browser
- convert markdown to word docx
- export markdown to pdf with diagrams
- render mermaid and graphviz diagrams in markdown
- format ai-generated markdown into a polished document
- convert readme to standalone html
- read local markdown files with nice themes

## When to choose
- you need pixel-faithful Markdown preview with diagrams, math, and code highlighting
- you want one-click export to Word, PDF, or self-contained HTML
- you prefer local-only processing with no data leaving your machine
- you want the same rendering across browser, Obsidian, VS Code, and CLI

## When to avoid
- you need collaborative or cloud-based document editing
- you require a license-approved dependency for commercial redistribution (license is NOASSERTION)
- you need a full Markdown editor rather than a viewer/exporter
