Four ways to write

Split View

Editor on the left, rendered preview on the right. See your changes instantly as you type.

Preview Only

Full-width rendered output. Perfect for reviewing your document before exporting.

Editor Only

Distraction-free writing with the full width dedicated to your markdown source.

Real-time markdown rendering

Glyphmark's live preview renders your markdown instantly — no delay, no compile step, no manual refresh. As you type a heading, it appears as a heading. Add a table, and it's formatted immediately. Drop in a code block, and syntax highlighting kicks in. The preview panel is a live mirror of your final document.

Split view for writing and reviewing

The default split view puts your markdown source on the left and the rendered output on the right. This is ideal for most writing workflows — you can check formatting, verify links, and preview Mermaid diagrams without switching contexts. The preview scrolls in sync with the editor, so you always see the section you're working on.

Full GitHub Flavored Markdown support

The preview panel supports the full GitHub Flavored Markdown specification: tables, task lists, strikethrough, autolinks, and fenced code blocks with language-specific syntax highlighting. Everything renders cleanly against Glyphmark's dark background, with colors tuned for readability across all six themes.

From preview to PDF in one click

Once your document looks right in the preview panel, you can export it to PDF with a single click. The PDF uses the same styles as the preview, so there are no surprises. This makes Glyphmark ideal for documentation, meeting notes, and any content you need to share outside the editor.

Frequently Asked Questions

Does the preview update as I type?+
Yes. The preview panel updates in real time with every keystroke. There's no save button or manual refresh needed — what you type is what you see.
What view modes are available?+
Glyphmark offers four view modes: Split View (editor and preview side by side), Preview Only (full-width rendered output), Editor Only (full-width markdown source), and Source mode. Switch between them using the toolbar or command palette.
Does the preview support syntax highlighting?+
Yes. Code blocks in the preview panel are syntax-highlighted using Prism.js with theme-matched colors. This works for dozens of languages including JavaScript, Python, TypeScript, Go, Rust, and more.
Can I preview Mermaid diagrams?+
Yes. Mermaid diagram code blocks render as interactive diagrams directly in the preview panel. Flowcharts, sequence diagrams, class diagrams, and more are all supported.
Does the preview match the PDF export?+
The PDF export uses the same styles as the preview panel, so what you see in the preview is very close to what you get in the exported PDF. Tables, code blocks, headings, and images all render consistently.
