Write in the source pane and watch the result beside it, or choose Write inline to edit inside a styled note. The split view can keep both panes in step as you scroll. Open a local .md or .markdown file, then download an edited copy or print the preview to PDF. The tool runs entirely in your browser: your text is not stored remotely.
What this preview is showing
The tool uses Cindermark, the open-source parser behind Ember’s native editor. It recognizes a CommonMark-oriented core and some editor-focused extensions. Cindermark does not claim complete CommonMark or GitHub Flavored Markdown conformance. A different Markdown tool may render a table, task list, callout, or wiki link differently.
The Markdown source is authoritative in both views. Inline styling is a browser interpretation of Ember's native editor; the underlying text is what you can take with you. Raw HTML and math are shown as escaped source rather than executed or typeset here.
Try a heading, a list, a link, and a task. Then download the file and open it in a text editor. That is the simplest way to see the relationship between Markdown syntax and a Markdown file.
The import limit is 1 MB to keep the browser tool responsive. Import replaces the current source after confirmation if you have changed it. The original file remains on your device; downloading writes a new copy.
For a general reference, read Markdown syntax or keep the cheat sheet nearby. The CommonMark specification is the primary reference for the core format.
