Markdown · rendered in your tab
Markdown,
read like a page.
Paste notes, a README, a changelog or a draft and CodeRush renders it as an article: headings, lists, quotes, tables and fenced code, side by side with the text you wrote.
- Compiler loads on demand
- Source and result together
- Nothing uploaded
Paste it and read it
No front matter required.
The detector recognises Markdown from its shape — headings, lists, emphasis, fences — so you do not tell it anything. The Markdown compiler is a vendored file that loads the first time a paste needs it, which is why an empty pad stays as quiet as it does.
Split view is the useful mode here: your source on the left, the rendered page on the right, updating as you type. Fenced code blocks stay code, and tables become tables, so a README reads the way it will read on a repository page.
The release notes template is a short document with headings, a list, a quote and a comparison table — a fast way to see how your own notes will look.
When the Markdown contains code
Reading it and running it are different acts.
Rendering Markdown shows the fenced blocks as code. Running the code inside them is a separate, deliberate move: paste a chat answer into the pad and CodeRush pulls the fences out and runs those instead, combining several blocks when an answer was split into HTML, CSS and JavaScript. A toast offers Keep the whole paste if what you wanted was the prose.
That is the difference between this page and running code from a chat answer. Same paste, two intentions, both one click apart.
Keeping a document
Local snapshots and links.
Name a snapshot and the document stays in this browser — up to 24 of them, pinnable, exportable as a single JSON backup and importable again later. Download the source when you want a .md file on disk.
A Rush link sends the document to someone else's browser with the source in the fragment. They see it rendered; nothing of yours becomes a file on a server.
Questions
- Which Markdown flavour is supported?
- The vendored marked compiler, which covers the common Markdown you write every day: headings, lists, emphasis, links, images, quotes, tables and fenced code.
- Is my document uploaded to render it?
- No. The compiler runs in your tab and the document stays in your browser unless you create a share link or send an AI request yourself.
- Can I preview a README before committing it?
- Yes. Paste it, read it in the preview, and edit in place. Split view keeps the source and the rendered page together.
- What happens to code blocks in my Markdown?
- Rendered as code. If you wanted the code to run instead, paste the text and CodeRush extracts the fences and runs them.
