macOS shows Markdown files as raw text. QuickMark adds a Quick Look extension: select any Markdown file, hit Space, and it renders with tables, code, Mermaid and math. It grew into a full editor for Mac, iPhone and iPad, with split view, tabs, export to PDF, Word, HTML, EPUB and PNG, and one-tap publishing to a read-only link. Reading and writing are free, no account, and files stay on your device.
This started as an annoyance, not a product idea. macOS previews .md files as raw markup, so every README meant opening a real editor to read four lines. I wrote a Quick Look extension so Space would just render the file. That was the whole app for months.
Then I kept wanting to fix typos in whatever I was previewing, so it grew an editor: source, split view with synced scrolling, preview. Tabs, an outline sidebar, find in page, over 30 code themes, six reading themes, and a sidebar listing the other Markdown files in the same folder so a docs directory behaves like a project. Export goes to PDF, Word, HTML, EPUB and PNG. You can also turn a document into a read only link.
Reading and editing are free, unlimited, no account, no trial clock. Files stay on your device. Pro is $9.99 once, covers Mac, iPhone and iPad on one purchase, and all it removes is the export and publishing limits. No subscription.
Two things I would rather say myself than have found out:
Quick Look, the folder sidebar and rich text copy are Mac only. On iPhone and iPad you get the editor, split view on iPad, and five export formats.
Happy to answer anything, including the awkward questions. If you want to see how it renders before installing, the same engine runs in a browser at quickmarkmd.com/preview.
