Pass Go, straight to preview.
A desktop app that opens Markdown files and shows them formatted, the way they're meant to look. Double-click a .md and you're reading it, not staring at raw # and *. When you do need to change something, one key flips you into an editor and back.
It's built with Tauri and React, so the download is small and it feels like a real Mac app rather than a web page in a window. Windows and Linux builds come from the same code.
Grab the installer for your platform from the latest release:
On macOS, download the .dmg, open it, and drag Markappoly into Applications. The build is signed and notarized by Apple, so it opens without security warnings.
On Windows, download and run the .msi.
On Linux, download the .AppImage (make it executable, then run it) or install the .deb.
After the first launch the app keeps itself up to date: when a new version ships it asks before downloading, then restarts into the new one.
Reading
- Formatted preview by default, with GitHub-flavored Markdown: tables, task lists, strikethrough
- Syntax-highlighted code, KaTeX math, Mermaid diagrams, and GitHub-style alerts (
> [!NOTE]) - Outline sidebar and folder browser, find-in-document (⌘F), and search across a whole folder
- Open Recent, word count and reading time, live reload when the file changes on disk
- Present mode (⌘⇧P): turn the document into slides, split on
---
Editing
- Toggle to a CodeMirror source editor with a formatting toolbar, or a split view (⌘⇧E) with editor and preview side by side, scrolling together
- Paste or drag an image into the editor to attach it next to the document
- Tick a checkbox in the preview and it writes the change back to the source
Export: Text, HTML, JSON (AST), Word (.docx), and PDF, plus Copy as HTML for pasting rich text elsewhere. With Pandoc installed, also RTF, EPUB, LaTeX, and Pandoc-rendered Word and PDF.
Native polish: frosted vibrancy on macOS and acrylic on Windows, system/light/dark themes, a native menu bar, drag-and-drop, "open with" file association, and a window that reopens where you left it.
