Supported: headings, paragraphs, emphasis, inline code, fenced code, quotes, lists, checkboxes, horizontal rules, basic tables and HTTPS links.
Privacy: text stays in this browser. Your draft autosaves locally; exported files are created on your device.
Security: raw HTML is shown as text, not executed. Only HTTP(S) links are clickable. This is a lightweight Markdown subset, not a full CommonMark implementation.
Shortcuts: Ctrl/Cmd+B for bold, Ctrl/Cmd+I for italic, Ctrl/Cmd+S to save Markdown.
