Is my text uploaded anywhere?

No. The Markdown is rendered by your own browser and never transmitted. That matters when you are previewing something unpublished.

Does my draft survive closing the tab?

Yes. The draft is saved on your own device as you type and restored when you return. It is stored locally, never on a server, and clearing it removes it completely.

Which Markdown flavour does it support?

GitHub Flavored Markdown: tables, fenced code blocks, task lists, strikethrough and autolinks, alongside everything in standard Markdown.

Can I open a .md file directly?

Yes. Drop a .md, .markdown, .mdx or .txt file anywhere on the page and it opens immediately.

Is raw HTML in my Markdown safe to preview?

Yes. Embedded HTML is sanitised before it renders, so a pasted document cannot run scripts against your browser.

Is my document uploaded?

No. Rendering happens in your browser, so an unpublished draft or an internal document stays on your machine. There is also no length limit, since nothing has to be transmitted or stored.

Rendering follows the CommonMark specification, so the output matches what GitHub and most editors produce. HTML embedded in your markdown is sanitised before display, which is a deliberate difference from a raw renderer.
