Write on the left, see the rendered result on the right. Formatting toolbar, live preview, word count, and one-click export to .md or .html. Everything stays in your browser.
The preview renders GitHub-flavored Markdown live via marked — tables, task lists, strikethrough and fenced code blocks all work. Editor and preview scrolling stay synchronized by relative document position.
The toolbar inserts or wraps Markdown syntax around your selection (or a placeholder if nothing's selected); Ctrl/⌘+B, I and K work as shortcuts for bold, italic and link.
Everything runs in your browser. Nothing you write is uploaded.
