About Markdown and MDViewer

Markdown is a plain-text format for writing clean, portable content. MDViewer helps you create docs faster with live preview, code blocks, Mermaid diagrams, math, and export workflows.

The problem we solve

Most markdown tools make you switch apps to preview Mermaid or math, or they lock you into one platform. MDViewer gives you one editor where diagrams and equations render live as you type, with the same app on web, desktop, and mobile—so the same .md file works everywhere. Free, no account required.

Why Markdown works

Readable in raw text and easy to review in git
Portable across GitHub, wikis, static sites, and CMS tools
Quick to write with minimal formatting friction
Great for long-form documentation maintenance

Useful syntax examples

# Heading for structure
**bold** and *italic* for emphasis
[label](url) for links
```ts ... ``` for fenced code blocks
```mermaid ... ``` for diagrams
