Outerline gives you space to think and space to write. A fast, fluid Markdown editor with no server, no database, and no clutter. Truly native on macOS and iOS. It works offline, opens instantly, and stays out of your way so you can just write. YOUR FILES STAY YOURS Every note is an ordinary .md file in a folder you choose, on your iPhone, in iCloud Drive, or anywhere in Files. No proprietary format and no account required to write. Open the same folder in any other Markdown app whenever you like, and take your work with you if you ever leave. A WRITING SURFACE, NOT A DASHBOARD • Live syntax highlighting, with each heading level at its own size • A keyboard toolbar with the formatting you actually reach for • Smart lists that continue, indent, and break out the way you expect • Auto-pairing brackets, quotes, and backticks • In-document search, word count, and reading time • Editor and preview, a tap apart • Choose your typeface, size, line height, and preview theme • Autosave, so a draft is never waiting on you to remember FIND ANYTHING FAST Full-text search across your whole library. Nested folders, Starred and All Documents views, and colored #tags you write inline and filter by later. Swipe to star, move, or delete. CONNECT YOUR IDEAS Link notes with [[wiki links]] and an autocomplete palette. The inspector shows what points here, each with a line of context and the folder it came from, keeps every external link in one place, and jumps you to any heading in the document. ANNOTATE WITHOUT TOUCHING THE MARKDOWN Highlight passages in five colors, attach notes to them, and leave anchored comments on any selection. Annotations live beside your files, so your Markdown stays clean and portable. NEVER LOSE A DRAFT Automatic timestamped snapshots, a diff viewer, and one-tap restore. Deleted notes move to Recently Deleted, where you can bring them back. WORK WITH SIRI AND SHORTCUTS Ask Siri to create or find a note, and use Shortcuts to open or append to one. On iOS 27, Siri and Apple Intelligence can use the open document as context on supported devices. Availability depends on language, region, and system settings. No Outerline account or subscription required. EXPORT, DIAGRAM, AND BACK UP Export any note as Markdown, HTML, or PDF. Write Mermaid diagrams in fenced code blocks and see them render in preview and in exports, entirely offline. Zip your whole library, metadata included, whenever you want a backup. THE SAME NOTES ON YOUR MAC This is the whole app, not a companion. Outerline for macOS syncs the same library as iOS, while adding split view, Quick Look, and an optional local Model Context Protocol server for AI assistants. Buy Outerline once on either platform and use it on both. Your Outerline account and Publish subscription carry across seamlessly. OUTERLINE PUBLISH (OPTIONAL) Publish a note to a link anyone can open, then keep it current as you save. Publishing needs a free Outerline account and an Outerline Publish subscription. Everything else in Outerline works without either. Outerline Publish is an auto-renewing monthly subscription. Payment is charged to your Apple Account at confirmation of purchase, and renews automatically unless you turn it off at least 24 hours before the end of the current period. Manage or cancel in your Apple Account settings. Terms of Use: https://outerline.so/support/terms/ Privacy Policy: https://outerline.so/support/privacy/

Millie is a private AI assistant that runs entirely on your phone. There is no server behind the chat. No account, no sign-up. Once you’ve downloaded a model, Millie works without an internet connection—on a plane or anywhere without a signal. Ask Millie to help you think something through: how to word a message you’re dreading sending, what to cook with what’s in the fridge, a gift for someone hard to buy for, a wedding toast, or an email you’ve been putting off. Choose between Millie, our flagship 35-billion-parameter language model built for deeper understanding and thoughtful answers, and Millie Flash, our lighter model built for the fastest replies. The flagship model can also understand photos and offers adjustable reasoning effort. Personalization lets you tell Millie about yourself and how you’d like it to respond. Because Millie runs on your phone instead of in a data center, it’s smaller than cloud AI. It’s weaker on niche facts and recent events, and it can be wrong, so check anything that matters. What it’s good at is thinking things through with you, privately. Before you install: The app requires at least 6 GB of RAM. That covers all iPhone 14 models and later, plus the Pro models of iPhone 12 and 13. iPhone 11 and earlier, the standard iPhone 12 and 13, and all iPhone SE models are unsupported. Millie Flash runs on supported phones with 6 GB. The flagship model requires at least 8 GB. The app shows which models your phone supports before downloading. The initial download is about 2 GB for Millie Flash or 8.6 GB for the flagship model. Download time depends on your connection, and chatting becomes available once the download finishes. Millie is made by LLMs For All, Inc.
