Markup vs Marklens

Markup reads and edits your Markdown beautifully — and it works with the folder of notes you already have, on your iPhone and iPad. POINT IT AT YOUR FOLDER — OR A GITHUB REPO • Open any folder of .md files from iCloud Drive or Files — the same vault you use on your Mac. Nothing to import, no lock-in. • Open a GitHub repo as a vault and read the whole thing offline. • Open several vaults and switch between them. READ LIKE A PAGE • High-fidelity rendering: syntax-highlighted code, LaTeX math, Mermaid diagrams, tables, task lists, and GitHub-style callouts. • Light / Dark / Sepia themes, adjustable text size and width, Dynamic Type. • Wikilinks, backlinks with context, a per-document outline, and tags. FIND ANYTHING • Full-text search with tag: and path: filters; fuzzy Quick Open. EDIT WITH EASE • A focused Markdown editor with smart lists, auto-closing brackets, table formatting, and inline [[wikilink]] and #tag autocomplete. • Insert images straight into your vault. Export or share as PDF, HTML, or Markdown. iPAD • Open documents in tabs; edit with a live rendered preview beside the source. • Hardware-keyboard shortcuts. HTML, TOO • Open and read .html and web bundles, with scripts off by default for safety. PRIVATE BY DEFAULT • No account required, no telemetry, no tracking. Your notes stay on your device and your iCloud. Signing in to GitHub is optional and only used to fetch the files you ask for. English and 简体中文, switchable in-app.

Marklens is a fast, native Markdown viewer for macOS, iPadOS, and iPhone. Open any .md file with a click and see it rendered immediately — beautiful typography, light and dark themes, syntax-highlighted code, and Mermaid diagrams. No editor, no library, no friction. 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.
