Telescopo is a full featured, native Mac workspace for people who want a better experience viewing documents not natively supported by macOS. View and export Markdown, LaTeX, Mermaid, PlantUML, SVG, PDF, ePub, and 70+ code and data formats with the speed and polish of a first‑party macOS app. All supported formats have been lovingly implemented for fast, fluid responsiveness and visually stunning themes. • Choose from six handcrafted themes for all supported filetypes— Light, Dark, Cyberpunk, Parchment, Bad Command, and Cyberspace—with seamless transitions across every format. Have unique themes for each open document tab or window, use System themes, or use the same thing for all documents. The choices are yours. • Instant rendering, instant export. Preview complex Markdown or LaTeX with MathJax, Navigate ePub chapters, or print Markdown to PDF with a single click. • Diagram power built in. Bring your Mermaid and PlantUML diagrams to life; Telescopo handles consented remote rendering, caching, and theme-aware SVG display automatically. • On-device Apple Intelligence summaries. macOS 26 users can condense Markdown documents locally—no cloud roundtrips, no privacy compromises. • Professional reading controls. Command-scroll zoom, Command-Option width adjustments, tabbed windows, fast search, table of contents, and smooth Metal-accelerated scrolling keep long documents effortless. • Code and data aware. Syntax highlighting, function detection, and theme-coordinated coloring for 40+ languages, plus native viewers for JSON, YAML, XML, CSV, logs, and more. • Mac-first experience. Accessibility, VoiceOver, drag-and-drop tabs, security-scoped bookmarks for local assets, release-note prompts via Setapp, and zero command-line setup. Telescopo combines serious performance with refined design. If your work spans prose, code, diagrams, and research, it’s the fastest, most beautiful way to keep every document at your fingertips on macOS.
