Release 2.0 turns MarkChrome from a simple editor into a complete Markdown workspace — still free, still no account, still 100% in your browser.

Split-pane live preview

Markdown on one side, beautiful rendered result on the other, with synchronized scrolling and GitHub-style tables, task lists and footnotes.

Syntax colours for dozens of languages with a one-click copy button on every code block.

Markdown validator

One click scans for unclosed code blocks, stray asterisks and broken table rows before you publish.
