Paste or drop Markdown to see it rendered as you type, with GitHub-flavoured tables, task lists and fenced code, and copy or download the HTML it produces.

## How to use it

1. Type or paste Markdown, or drop a .md file.
2. The preview and HTML update as you type.
3. Copy the HTML or download it.

## Details

- **Syntax:** CommonMark + GFM: tables, task lists, strikethrough, autolinks, fenced code
- **Safety:** Raw HTML in the input is escaped; the preview is a sandboxed frame with scripts disabled
- **Engine:** marked (MIT)

## Questions

### Is this the same as GitHub's renderer?

Very close for everyday Markdown: tables, task lists and fenced code match. GitHub adds extras such as @mentions, emoji shortcodes and Mermaid diagrams, which aren't rendered here.

### Why is my HTML shown as text?

Raw HTML in the input is escaped on purpose, so pasted content can't run scripts. Use Markdown syntax for formatting.

### How do I make a line break without a new paragraph?

End the line with two spaces or a backslash, or turn on 'Single line breaks become <br>', which matches GitHub comments.

### Can I get the HTML for my site?

Yes, copy or download it. It has no styles, so it takes on your site's CSS.

### Is what I type sent anywhere?

No. The calculation runs in this browser tab with the same code our MCP server uses. Nothing you type is sent to a server or saved, apart from settings like filing status, which stay in this browser.

### Can an AI agent use this?

Yes. The same function is a tool on our free MCP server at tools.cuelark.com/mcp, so ChatGPT, Claude or Cursor get exactly the answer this page shows. 'Copy MCP call' gives you the arguments.
