A Markdown editor that respects both the source and the page.
Lumen Markdown is built for people who live in Markdown files — documentation writers, engineers and consultants. Three editor modes let you work in raw source, a live split preview, or edit the rendered document directly. A folder becomes a workspace with a file tree, outline, tabs and search-and-replace across every file. Everything stays on your machine.

Apple Silicon build. Intel Mac, Windows and Linux builds are not yet published — the app supports them, but each needs a build on that platform.
Source with CodeMirror 6 syntax highlighting, a resizable split preview with scroll sync, or Live WYSIWYG that edits the rendered document and serialises straight back to Markdown.
File tree, heading outline, tabs with unsaved-change protection, and search-and-replace across every Markdown file — open files update undoably, closed files are written to disk.
Native .docx with headings, tables, lists, code blocks and embedded images, plus self-contained HTML and PDF through the system print dialog.
LaTeX renders as native MathML, mermaid fences render as diagrams, and GitHub-Flavored Markdown covers tables, task lists, autolinks and sanitised raw HTML.
Zen and focus modes with typewriter scrolling, per-document word goals, debounced autosave, reading time, and session restore that reopens your folder, tabs and view modes.
The Rust backend validates every path and restricts file operations to .md, .markdown, .mdx and .txt, behind a scoped Tauri capability set. Nothing leaves your machine.
The command palette covers every action; these are the ones worth committing to muscle memory.

These utilities are built and signed locally, not yet notarised through Apple's Developer ID programme. macOS will warn you the first time you open one. That is Gatekeeper doing its job — here is how to proceed if you trust the source.
