Quirely Markdown+LaTeX Editor vs Recto MD

Quirely is two full editors in one native app: real Markdown and real LaTeX. Neither is a bolt-on. If you only ever write Markdown, you get a complete, beautiful Markdown app — nothing hidden behind TeX. If you live in LaTeX, you get a genuine editor that compiles your projects — not a Markdown app with math sprinkled in. A CALMER READER Open a file and just read. Quirely renders clean, typographic Markdown — never forcing a split screen or a cramped editor when all you want is the page. Switch to Code, Edit, or Split only when you choose. Quick Look previews .md and .tex straight from Finder. MARKDOWN, RENDERED RIGHT - Mermaid diagrams: flowcharts, sequence diagrams, and more — live, and styled to your theme. - LaTeX math: inline and block equations, typeset beautifully. - Code blocks with syntax highlighting for dozens of languages. - Tables, task lists, footnotes, callouts, full GitHub-flavored Markdown. EDIT LIKE A PRO - Four modes: View, Code, Edit (block editor), and Split. - Word-processor formatting: bold, italic, underline, strikethrough, highlight, links, super/subscript — with theme-aware colors. - Drag-and-drop block editing: reorder paragraphs, lists, tables, and diagrams by hand. - Visual Mermaid editing: drag nodes, add edges, recolor — no syntax required. - Spreadsheet functions in tables: =SUM(A1:A3), =AVERAGE, =IF and more, with a full function keypad on Mac. - Collaborate over bonjour. Share a workspace or document and each collaborator can edit with their own cursor and view. Entirely private; no external servers A REAL LATEX EDITOR - Open and compile .tex — single files or full projects with a root document, chapters, and BibTeX. - The same four modes: read the typeset PDF, edit raw source with themed syntax highlighting, or use structured Edit mode — rendered paragraphs, equations, and tables you double-click to edit. - Chapters open inline in the root document and save back to their own files. - Tabular grid editor with the same spreadsheet formulas as Markdown tables. - SyncTeX jump between source and PDF; rendered diffs between versions (latexdiff). - Export LaTeX to PDF, HTML, or clean Markdown — cite/ref/figure numbering intact. - LaTeX stays classic black-and-white by default; apply your theme with one toggle. FEYNMAN DIAGRAMS Build QED/QCD diagrams visually — vertices, propagators, gauge bosons, loops — or paste tikz-feynman. Quirely renders them natively and derives the amplitude iℳ from the Feynman rules; edit the equation and get the diagram back. Free on every tier. MAKE IT YOURS Ten hand-tuned themes recolor every token — headings, code, links, tables, diagrams. Duplicate any theme and edit every color, font, and size. Switch live. A REAL WORKSPACE - Open a folder with file navigation, backlinks, and tabs. - Semantic search and exact full-text search. - Version history with rendered diffs. - Mark positions to insert text across documents. ON-DEVICE AI (Pro) Draft, rewrite, and synthesize across your notes with Apple Intelligence — on-device, no API fees, no account. EXPORT & SHARE Polished HTML or paginated PDF with your theme, math, and diagrams intact. PRIVATE BY DESIGN Everything runs on your device. Your files stay plain Markdown and LaTeX you own — no account, no lock-in. ONE APP, EVERY DEVICE Universal for Mac, iPad, and iPhone. One-time purchases — never a subscription. Write in Markdown or LaTeX. Read either beautifully.

Recto MD opens a Markdown file and gets out of the way. Open one from Files, Mail or Safari with Open in Recto MD, or share it in from any app. On iPadOS and iOS 26, Files > Get Info > Always Open With makes it the default. Reading comes first: pick a file and it is on screen, typeset and ready, nothing to configure. When you want to change something, Edit mode puts the source next to the live preview - side by side on iPad, a Source/Preview switch on iPhone - and Save is explicit, so nothing is written until you ask for it. TYPOGRAPHY FIRST The reading column, the leading and the vertical rhythm are the product. Pinch to zoom the whole page from 50% to 300% - text, measure and margins scale together, the way a browser's page zoom does - the column measure also has three widths, and the page is laid out so a long document stays comfortable rather than merely legible. RENDERS WHAT YOUR DOCUMENTS ACTUALLY CONTAIN - CommonMark and GitHub Flavored Markdown: tables, task lists, strikethrough, autolinks, footnotes - GitHub-style alerts: NOTE, TIP, IMPORTANT, WARNING, CAUTION - Mermaid diagrams, loaded only when a document has one - Mathematics and chemistry, typeset by KaTeX: inline and display LaTeX, and mhchem chemical equations. The delimiters are narrow on purpose, so a price written as $5 stays a price - Syntax-highlighted fenced code blocks, with a copy button - Wide tables scroll inside the reading column, so the page itself never scrolls sideways EDITING, WHEN YOU WANT IT Edit mode puts a source pane beside the live preview - side by side on iPad, a Source/Preview switch on iPhone. Save is explicit, and nothing autosaves in the background. Export the document as a PDF whenever you want a copy to share. FIND YOUR WAY AROUND An outline is generated from the document's headings: a sheet on iPhone, a sidebar on iPad that also holds your recent documents. Search inside a document with a live match count and step through the matches. Recents remembers where you stopped reading and puts you back there. IT UPDATES WHILE YOU READ Change the file somewhere else and the document updates in place - same scroll position, no flash, no reload button to hunt for. If you have unsaved edits, the app stops and asks instead of choosing for you. Turn auto-reload off and you get a "File changed" tap target instead. A THEME EDITOR, NOT A THEME PICKER Duplicate a built-in theme or start from nothing, and tune it in six groups: text (font, scale, line height, spacing, indent, justification); headings (font, weight, an accent color, rules, and a size for each of the six levels); layout (column width by characters, points or percent, a max width, custom margins, a page-card look); sidebar (font size and step per level, row height, indent, background and accent mix); blocks (code font and size, table density and zebra striping, blockquote style, the code syntax palette); and color, down to the selection highlight. Import or export any theme as JSON. OFFLINE, AND PRIVATE BY CONSTRUCTION The app makes no network requests at all. No account, no sign-in, no analytics, no tracking, nothing collected. Your documents are files on your device or in your iCloud Drive, and that is where they stay. BUILT FOR THE PLATFORM Dynamic Type through to the accessibility sizes, VoiceOver reading real document structure, Increase Contrast, Reduce Motion and Reduce Transparency are all honoured. With a hardware keyboard, every navigation shortcut is independently rebindable - pick the key, choose Command, Option or Shift, and the app flags a conflict before you save one - and Open, Find, Find Next, Reload, the zoom commands and Settings are all one keystroke away, listed in the Command-hold sheet. The interface is available in twelve languages, with a System option and a picker for the one you want.
