Markdown preview, without uploading the draft

• Headings with # through ######.
• Emphasis — *italic*, **bold**, ~~strikethrough~~.
• Lists, ordered and unordered, including nesting; task lists with - [ ].
• Links and images, block quotes, inline code and fenced code blocks.
• Tables in the pipe format most static site generators use.
• Horizontal rules, and raw HTML — sanitised before it reaches the page.

Markdown is designed to be readable as plain text, but the things that go wrong are structural: a table with the wrong number of pipes, a list that needs a blank line before it, a code fence that never closes. Those are much easier to see rendered than counted.

It is also a way to check what a CMS will do with the file. Paste the draft, look at the tables and the nesting, then fix the source before it goes into the build.

• No footnotes. The renderer follows the common GitHub-flavoured syntax; footnotes are not part of it.
• No custom CSS or themes. The preview uses the site's typography so it reads like a document, not like a debug pane.
• No file upload from disk. Paste the text. Reading a file would work, but it is one more permission for a task that takes a copy and a paste.
• Not an editor. If you want to write rich text and export Markdown — rather than type Markdown — that is what Quorly's editor does.

The renderer is marked, sanitised with DOMPurify, both self-hosted on this origin. There is no request to a conversion API: the Markdown is parsed by JavaScript in this tab and written into the preview element. The only stored copy is one localStorage key, so a reload does not lose what you pasted; Clear removes it.

Drafts that should not be on a stranger's server — a client document, an unpublished chapter — are exactly the ones people paste into random converter sites. This one does not need the network at all after the page loads.
