MarkShelf is a fast, keyboard-first Markdown reader for macOS. Point it at any folder and it becomes a polished, navigable library — no database, no import step, no proprietary format.
Why people use it
• Quick Open (⌘⇧O) — fuzzy search every .md file in your workspace in microseconds.
• Folder tree that follows you — opening a file from search, Finder, Recents, or a wiki-link auto-expands and reveals it in the sidebar.
• Tabs with back/forward — navigate wiki-links the way you navigate code.
• Live updates — FSEvents keep the tree and search index fresh as your folder changes.
• Built-in Mermaid diagrams and a clean, theme-aware preview.
• Remembers where you stopped reading — per-file scroll position, tab session, and folder expansion all persist across restarts.
• Opens quickly, exits quickly. Zero telemetry. No account required.
Multi-folder workspaces
Add as many local folders as you like — a personal vault, a company wiki export, a docs repo. Switch between them from the toolbar; each workspace keeps its own tabs, recents, and tree state.
Designed for your keyboard
Quick Open, outline sidebar, tab navigation, zoom, focus reading mode — every frequent action is a shortcut.
Privacy
MarkShelf runs fully in the macOS sandbox with access only to the folders you explicitly add. Nothing leaves your machine. No analytics, no ads, no accounts.
