The Art of Reading Markdown
A beautiful, offline-first macOS app that faithfully reproduces GitHub-style Markdown rendering. Because reading Markdown should be a quiet, deliberate act of understanding.
Why Arto?
Arto has evolved beyond a basic Markdown viewer. It combines faithful rendering, powerful navigation, flexible automation, and refined reading workflows in one native app.

Built with Rust for blazing-fast performance. Opens instantly, renders quickly, and uses minimal system resources.
Dedicated Viewer Windows
Open Mermaid diagrams, math expressions, and images in focused viewer windows with zoom/pan interactions.
Smart Copy Workflows
Use context-aware copy actions, including Copy As... variants for text, code, tables, and rendered blocks.
Custom Keybindings
Edit shortcuts and choose preset mappings (Default, Vim, Emacs) to match your muscle memory.
Powerful CLI Integration
Open files/directories with single-instance routing and window control options like --open and --directory.
