Quirely Markdown+LaTeX Editor vs Musing Notes

Quirely Markdowns is the document editor that stores everything as Markdown. Quirely Markdowns is a native Markdown app for Mac, iPad, and iPhone — built for people who care how their writing looks and reads. It stays out of your way when you want to read, and hands you real tools when you want to edit. A CALMER READER Open a file and just read. Quirely renders clean, typographic Markdown — it never forces you into a split screen or a cramped editor when all you want is to take in the page. Switch to Code, Edit, or Split only when you choose. Quick Look support lets you preview .md files straight from Finder, without even opening the app. RENDERING THAT ACTUALLY WORKS - Mermaid diagrams: flowcharts, sequence diagrams, and more — rendered live and styled to your theme. - LaTeX / KaTeX math: inline and block equations, typeset beautifully. - Code blocks with syntax highlighting for dozens of languages. - Tables, task lists, footnotes, callouts, and full GitHub-flavored Markdown. EDIT LIKE A PRO - Four modes: View (read), Code (raw source), Edit (block editor), and Split (write and watch it render). - Word-processor formatting: bold, italic, underline, strikethrough, highlight, links, super/subscript — with a font-size slider and theme-aware text and highlight colors. - Drag-and-drop block editing: reorder paragraphs, lists, tables, and diagrams by hand. - Visual Mermaid editing: drag nodes on a canvas, add edges, and recolor — no syntax required. - Spreadsheet functions in tables: type =SUM(A1:A3), =AVERAGE, =IF and more, with a full function keypad on Mac. - Nested lists that mix ordered, bulleted, and checklist levels. MAKE IT YOURS Ten hand-tuned themes — light and dark — recolor every token: headings, code, links, table borders, even diagram colors. Duplicate any theme and edit every color, font, and size. Switch live; no restart. A REAL WORKSPACE - Open a folder of notes with file navigation, backlinks, and tabs. - Search by meaning (semantic search) and by exact full-text match. - Version history with rendered diffs — see exactly what changed between saves. - 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. Ask AI about your whole workspace, or compose inline as you write. EXPORT & SHARE Export to 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 you own — account. ONE APP, EVERY DEVICE Universal for Mac, iPad, and iPhone. One-time purchases — never a subscription. (Some editing tools, like the block inspector and the spreadsheet function keypad, are richest on iPad and Mac; formulas work everywhere by typing.) Write in Markdown. Read it beautifully.

Some ideas arrive half-formed — at a café in the rain, on a walk, the moment before sleep. Musing is built to catch them, and to give them back to you exactly when you need them. You don't file. You don't sort. You don't tag. You just write — or speak — and move on. Later, you find any note the way you'd ask a friend: "What was that wine I liked?" "The café idea when it was raining." FREE · PRIVATE · ON YOUR DEVICE Musing is free — no ads, no account, no subscription, no credits. Capture, context, photos, and text search work on every supported device. Ask answers and semantic recall use Apple Intelligence on devices that support it — otherwise search stays useful without them. No server ever reads a note by default, nothing trains a model, and notes sync only through your own private iCloud — across iPhone, Apple Watch, and Mac. SEARCH BY THE MOMENT Every note quietly keeps its moment — neighborhood, weather, time of day, the kind of place. So you can ask by it: "coffee shop notes," "rainy day ideas," "notes from Traverse City," "late night notes" — or combined, "receipts from Oak Park last month." Instant, even offline. JUST ASK Search isn't a keyword box. Type what you're looking for in plain language and Musing surfaces the notes that match — even when you don't remember the exact words. Questions get answers grounded in your own notes, citing the notes they came from. CATCH IT HOWEVER IT ARRIVES Type a quick thought. On iPhone, speak a voice note — transcribed on-device; on Mac, dictate straight into the composer. Attach a photo and Musing reads what's there on your device — a receipt gets its total, a grocery list becomes a checklist. Check in to save a place. On iPhone: Home Screen widget, Siri, Shortcuts, Apple Watch, and the share sheet. On Mac: a menu-bar capture that never needs the main window, plus a Reading Room for asking and browsing. YOUR PLACES A quiet map of everywhere you've paused — most-visited spots and neighborhoods, on iPhone and in a dedicated Places window on Mac. WHEN YOU RETURN Walk back into a café you've written in and that note can meet you on Home — a quiet lock-screen banner too, if you ask. A year on, an echo: Time Recall brings the note back with the weather and the street still on it. Place Recall and Time Recall (Echoes) stay off until you turn them on. Hospitals, clinics, and places of worship stay unnamed, and never trigger. FIVE ROOMS TO WRITE IN Choose how Musing feels. Foolscap, Inkwell, Verdant, Dusk, or Harbor. Light and dark work in every theme. BRING YOUR OWN AI SERVICE Optional Pro Mode lets you paste your own OpenAI or Anthropic API key so Ask and web lookup can use GPT or Claude. You choose the provider, use your own account, and keep usage and costs under your control. Off by default — not a paid upgrade inside Musing. Capture, search, and tags stay on this device. Nothing trains a model. PRIVATE BY DESIGN Sensitive places — clinics, hospitals, places of worship — are never named. Every context signal has an off switch. NO FOLDERS. NO FEED. NO BUSYWORK. Capture a half-formed idea. Find it later. Free. Private. Yours.
