Doku: Markdown Viewer & Reader
Open any .md in Quick Look
Only for Mac
$14.99
Mac
The AI wrote it in Markdown. Doku makes it readable: twelve themes, Quick Look in Finder, and summaries that never leave your Mac.
Doku opens Markdown files and makes them look right.
FOR THE FILES AI WRITES
Your assistant hands you a .md file and macOS has nowhere good to open it. Doku does. Drop any Markdown file on it and read it the way it was meant to look.
BEAUTIFUL BY DEFAULT
Twelve document themes, most with a light and a dark version, and you choose which one you see. Headings, tables, task lists, footnotes and code all render the way they should, with syntax highlighting for 40+ languages.
RIGHT IN FINDER
Press Space on any .md file to preview it without opening the app. Markdown files get real thumbnails instead of blank page icons.
BUILT FOR READING
Doku is a reader, not an editor. Keep writing wherever you write. Doku shows you the result and refreshes the moment the file changes on disk.
Summarise long documents on device. Export to PDF. Search inside a document, jump between headings with the table of contents, zoom, and open several files as tabs in one window.
PRIVATE BY DESIGN
No account. No network. No telemetry. Every document is rendered on your Mac and never leaves it.
