Frequently asked questions

What Markdown features are supported?

Headings, bold/italic/strikethrough, ordered and unordered lists, links, images, inline and fenced code, blockquotes and rules.

Can I get the HTML?

Yes — the rendered HTML source is shown beside the preview and is copy-ready.

Is it private?

Every calculation happens on this page, in your own browser. Your input is never sent to a server, never logged and never used for training — which also means the tool keeps working when you are offline.
