Read full description

MDReader opens your Markdown files and folders and renders them properly. There is no library to import into, no account to create and no sync service in the middle. Your .md files stay exactly where you put them, and MDReader reads and writes them in place. FAST, EVEN ON BIG FILES A two-tier parser scans a document in a single pass and only fully parses the blocks you can actually see. A 10 MB file opens before other editors have finished showing a spinner, and scrolling stays smooth all the way down. RENDERS THE WHOLE OF MARKDOWN GitHub-flavoured Markdown with tables, task lists you can tick straight from reading mode, footnotes that jump both ways, YAML front matter shown as a card, LaTeX math inline and display, fenced code with syntax highlighting, and Mermaid diagrams rendered offline. AN EDITOR THAT STAYS OUT OF THE WAY Live syntax highlighting, lists that continue and renumber themselves, bold/italic/link shortcuts, find and replace, table and formula inserters, and paste an image to save it next to the document. Autosave goes through the system file coordinator, so editing alongside Obsidian, git or iCloud is safe. PICKS UP WHERE YOU LEFT OFF Reading position is restored to the pixel, per document, across relaunches, rotation and window resizes. FOLDER WORKSPACES (PRO) Open a whole folder: a repository's docs, an Obsidian vault, a Zettelkasten. Fuzzy quick-open, full-text search across every file in the folder, [[wiki-links]] with a backlinks panel, a front-matter tag browser, and read-only git status per file. Changes made by other apps are picked up in place, without losing your position. MORE IN PRO PDF export and print, publishing to GitHub Gist and Telegraph, presentation mode for slides, a custom theme editor with imported fonts, focus and typewriter modes, word-count goals, reading statistics, text-to-speech with follow-along highlighting, local version history with diffs, snippets, Vim keybindings, and an AI pack that summarises and rewrites entirely on device. BUILT FOR APPLE PLATFORMS One purchase covers iPhone, iPad and Mac. Keyboard shortcuts throughout, multiple windows, menu bar commands, a Share extension, Shortcuts actions, widgets, a URL scheme, Spotlight indexing, VoiceOver labels and Dynamic Type. PRIVACY MDReader collects nothing. No analytics SDK, no account, no server of ours to talk to. The only network traffic is what your own documents ask for, such as remote images, plus the publishing integrations you set up yourself. FREE AND PRO The reader and the single-file editor are free forever: all rendering including math and syntax highlighting, the base themes, table of contents, in-file search, HTML, Markdown and plain-text export, and position restore. Pro unlocks folder workspaces and the power features above, as a one-time purchase or as a yearly subscription with a free trial. SUBSCRIPTION AND PURCHASE DETAILS MDReader Pro (Yearly) - auto-renewable subscription, 1 year, USD 9.99 per year, including a 7-day free trial for new subscribers.

About

PureOpen

Features
Read full description

PureOpen is a Markdown editor for Mac and iPhone built for right-to-left writing. Most editors treat RTL as a switch: turn it on and the whole document flips, which breaks the moment you write Hebrew or Arabic with English words in it. PureOpen decides direction per block instead. Every paragraph, heading and list item takes its direction from the first strong character in it — so a mixed document displays correctly with no setting, and with no direction marks written into your file. Files open in tabs, the way a browser opens pages, and your changes are on disk 600ms after you stop typing. RIGHT-TO-LEFT, PER BLOCK • RTL and LTR live side by side in one file. A Hebrew paragraph aligns right, the English paragraph under it aligns left, and each stays that way as you edit. • A Hebrew or Arabic sentence with English terms, code spans and links inside it reads correctly — the block stays RTL and the Latin runs sit where they belong. • A block with no strong character inherits the direction of the block above it, so blank lines and numbers don't break the flow. • Nothing is added to your Markdown to make this work: no RTL marks, no wrapper tags. The file stays portable. OPEN IT FROM THE FILE, NOT FROM THE APP • Right-click a Markdown file in Finder — or long-press it in Files on iPhone and iPad — and PureOpen sits at the top of "Open With". One click and the document is open in a tab in the window you already have. • No launching the app first, no file picker, no importing into a library. Double-click works the same way, and so does dragging a file onto the window. • Registered as the owner and editor of .md, .markdown, .mdown and .mkd. TABS • Every file opens in its own tab. ⌘1ā€“āŒ˜9 jump by position, Ctrl+Tab cycles, middle-click closes, and ⌘W closes the tab rather than the window. • The tabs you had open come back the next time you launch. SAVING • Autosave writes 600ms after you stop typing, and again on tab switch, tab close and window blur. A grey dot marks a tab with unsaved content. • If the file changes on disk — another editor, a sync client — it is reloaded quietly and your scroll position is kept. If it is deleted, editing locks so stale content is not written back over it. • Opening a file doesn't reformat it: an edit that didn't actually change the content doesn't trigger a write. EDITING • 17 formatting buttons: headings 1–4, bold, italic, underline, strikethrough, bullet, numbered and task lists, subscript, superscript, quote, inline code, code block and horizontal rule. • Each button reflects the block and the marks under the cursor, and updates as the cursor moves. • Underline, subscript and superscript are kept as HTML rather than dropped when the file is saved. PRINTING AND PDF • Print what you see. The page is the document as the editor renders it — headings, tables, task lists, code blocks, Hebrew and English side by side — without the tabs and the toolbar around them. • Export the same page straight to a PDF file, without going through the print dialog to find "Save as PDF". • Nothing is rendered a second time for paper, so what prints is what you were looking at. Pages break between lines, and the page is always light even when the app is in dark mode. ALSO • On iPhone and iPad, files opened from Files are edited in place — not copied into the app. • Dark mode follows the system setting. • Files past roughly 4 million characters open read-only as raw text, so the interface doesn't stall. • No network, no account, no telemetry. Your files stay on your device. PureOpen is free, with no in-app purchases.
