em is a Markdown writing app for Mac, iPad, and iPhone, built on one idea: your writing files are yours, and you're the only one who should decide what to do with 'em. WRITE 'EM WITH MARKDOWN Capture your thoughts in a distraction-free Markdown editor tuned for each device. em counts your words and reading time, but only if you want it to. FIND 'EM WITH SMART SEARCH Smart Search lists every file holding your words, the ones holding all of them first. Use quotes, +, -, OR and * for precision, filter by library, tag, status or year, and save any search as a Smart Folder that stays current. Only remember what a piece was about? Ask em. PROTECT 'EM WITH VERSION HISTORY Every edit is automatically versioned and backed up to iCloud. Compare and restore versions from any device, so an accidental deletion never costs you your writing. PUBLISH 'EM WITH GHOST Connect em to your Ghost site to edit, back up, and publish natively in Markdown that maps to Ghost's cards. em supports 19 Ghost editorial cards, plus drafts, scheduling, and newsletters. EXPLORE 'EM WITH AI (BUT ONLY IF YOU WANT TO) Ask em questions and get answers grounded in your files, not the internet. On OS 27, Siri can search, add, or edit notes in the libraries you approve. Get an Editorial Review from a prompt you can read and edit — it's a document in your library. em doesn't write your drafts; it helps you edit 'em. ALL FEATURES - Smart Search: Search operators, filters, and Smart Folders - Version History: Automatic versioning, stored in iCloud - Ghost Sites: Sync, edit, publish, and send newsletters - AI on Your Terms: On-device Apple Intelligence by default; optionally Claude, ChatGPT, or Gemini with your API key - Siri AI: Search, add, or edit notes in approved libraries (OS 27) - Ask em: Answers from your own archive - Editorial Review: AI feedback from a prompt you control - Apple Shortcuts: Start an AI conversation or publish to Ghost - Journaling Suggestions: Capture memories in Markdown (iOS) - Read Aloud: Hear your draft to catch what your eyes miss - Customization: Reader and Editor fonts and colors - Export: Save any Ghost post as a Markdown file - Offline Editing: Works without an iCloud or Ghost connection - Even More: Printing, word counts, and yes — em dash highlighting PRIVACY, PLAINLY em has no server. That's not a promise about what the developer does with your data — there's no backend, no account, and no company database where your writing could end up. Your writing syncs through your iCloud and nowhere else. AI features are off by default and, if turned on, run on-device with Apple Intelligence. Want a larger model? Connect Claude, ChatGPT, or Gemini with your own API key — your account, your billing, revocable anytime. em names the model answering, every time. Transparency Statement: AI was used in developing this app, but every feature idea, design call, and architectural decision was made by a human.

Skein is a notes app for people who want to keep their own files. Your vault is a folder of plain Markdown on your device or in iCloud Drive. Skein reads and writes those files directly — the same folder you open in Skein for Mac, or in any other editor. Nothing is locked in a database, and there is no service in the middle. Write it down before you lose it The app opens on a capture field. Type the thought and send it; the first line becomes the note's title and Skein files it where you told it to. No dialog, no folder picker, no naming a file before you have written anything. Find it again Search matches titles the moment you start typing and searches inside every note once the index is ready, ranked, with the matching lines and their line numbers — tap one and land on it. The Vault filters by name, by #tag or by folder in one field, and tags are real: tap one anywhere in the app to see everything carrying it. Real Markdown, properly Headings, lists, task lists, tables, footnotes, code blocks, callouts, ==highlights== and [[wikilinks]] — read cleanly and edited as text. A keyboard bar puts the things you actually reach for above the keys, including arrows that move by character and by word, and you can choose which of them appear. Type / for a command, #for a tag it already knows. Canvas Open a JSON Canvas board, move cards, connect them, colour them and write on them. The same file, the same format Obsidian writes, so a board made on the Mac opens here and back again. It keeps your writing safe Skein keeps earlier versions of a note as you edit, so you can go back to what you wrote this morning. When the same note has been changed in two places, Skein keeps both and asks — it never picks a winner quietly. Also Share text from any app straight into your vault. Four themes, including one for reading at night. Dynamic Type throughout, and full VoiceOver support. Skein does not have an account, a subscription for the basics, a server, or telemetry. Your notes never leave your device except through iCloud Drive, which is yours. Skein for Mac is a separate app on the same purchase.
