Telescopo

Telescopo exists to make reading Markdown as beautiful as writing it.

Markdown powers documentation, research papers, and open-source projects worldwide — yet on macOS, there hasn’t been a dedicated, high-fidelity viewer for it. Not a browser tab. Not an editor sidebar. A viewer, purpose-built for the reading experience.

Telescopo is one of the few actively developed native macOS document viewers. Built entirely with Apple’s Metal framework, it renders Markdown, LaTeX, Mermaid diagrams, code files, SVGs, ePubs, and 70+ other formats with GPU-accelerated precision and fluid animations.

The core Markdown viewing experience is free for everyone. We believe democratizing access to beautiful document rendering shouldn’t require a paywall. Dynamic fonts, chapter navigation, search, and multiple windows are all included at no cost.

For power users, Telescopo Pro unlocks the full suite: 70+ file formats, on-device AI summaries via Apple Intelligence, 6 handcrafted themes with animated Metal backgrounds, syntax highlighting for every major programming language, and styled PDF export. One-time purchase. No subscriptions. No accounts. No tracking.
