HIGHLIGHTS • Instant render — every .md opens in a clean, focused window • 30+ language syntax highlighting via highlight.js, bundled offline • Mermaid 11 diagrams — flowcharts, sequence, state, xy-charts and more • GitHub-Flavored Markdown — tables, task lists, footnotes, strikethrough • Light and dark theme matching the system appearance • Quick Look on macOS — press Space on any .md in Finder for a rendered preview • Export to PDF on every platform • Pinch-to-zoom on iPadOS and iPhone, ⌘+ / ⌘− / ⌘0 on macOS • Open files via drag-and-drop, the Share Sheet, or the Files app MADE FOR READING Marklens doesn't try to be a notes app or a knowledge base. It opens a file, renders it perfectly, and gets out of the way. If you write Markdown in another tool — VS Code, Obsidian, GitHub, your favorite text editor — Marklens is the viewer you reach for to look at the result. PRIVATE BY DESIGN Marklens collects nothing. No analytics, no telemetry, no crash reports, no network requests. Every rendering asset — Mermaid, highlight.js, fonts — ships inside the app. Read the full privacy policy at https://donald-jackson.github.io/marklens/privacy/ OPEN SOURCE Marklens is MIT-licensed and developed in the open.
