Markdusk

a Mac-native markdown editor

It just opens the file. No account, no cloud, no plugins, no knowledge-management religion — fast and native, the way TextEdit should have been.

The Markdusk editor showing soft-WYSIWYG markdown in the Smoke theme

Why it exists

The default .md experience on a Mac is TextEdit showing you raw asterisks. The good alternatives are paid (Bear, iA Writer, Typora) or ask you to adopt a whole methodology (Obsidian). Markdusk is the third option: free, fast, native, and opinionated — it opens the file and gets out of the way.

Soft WYSIWYG

Markers hide on inactive lines, stay on the line your cursor is on. Live KaTeX and Mermaid in the buffer.

Fast everything

Rust core, Tauri shell — no Electron. Opens from Finder in under a second; stays smooth past a megabyte.

Focus Mode

iA-style sentence and paragraph dim with typewriter scroll, for when the draft needs all of you.

Keyboard-first

Command palette, fuzzy switcher, multi-cursor, regex find & replace, table tools that keep the pipes aligned.

Wikilinks, no vault

[[file]] autocompletes and ⌘-click jumps — local linking without moving into Obsidian.

A theme with a face

Smoke, Amber, and Verdure — a herbal Art Nouveau palette most editors would never ship.

It's not a knowledge base, not a CMS, not collaborative, not cross-platform, not AI-first. Mac-only, on purpose.
