Everything in Metis

• Live mode: Markdown styles render as you type; syntax markers hide on inactive lines
• Wysiwyg mode: Markdown syntax hides on every line as you write; select text for a floating format bar (Cmd-B / Cmd-I / Cmd-K)
• Wysiwyg on iPhone and iPad too (Settings → Editor): the same hidden syntax and typing rules, with formatting buttons above the keyboard and tappable checkboxes
• Separate Reading mode renders the full document
• Images, GFM tables, code highlighting, and native LaTeX math ($…$ / $$…$$)
• Mermaid diagrams from ```mermaid fences (flowcharts, sequence, class, state, ER, gantt, pie)
• An Inspector column beside the note (Opt-Cmd-I): Outline maps every heading, follows your cursor, and jumps you anywhere in one click - in Live, Wysiwyg and Reading. On iPhone it opens as a sheet
• Editor & reading themes - Metis Light and Metis Dark, the app's own palettes, plus Dracula, Nord, Solarized, Gruvbox, Tokyo Night, One Dark, Monokai, GitHub, Catppuccin (System follows light/dark)
• A theme recolors the whole app, buttons, links and selection included; on top of it you can pin your own text, background, heading and link colors - a custom background colors the note, not the app chrome
• Optional line numbers; a collapsible connections panel for more editing space

• A vault is a folder of notes; switch between multiple vaults (one per client/company)
• Expandable folder tree with per-folder note counts and a clickable breadcrumb
• Create, rename, delete folders; drag a note onto a folder to move it
• Multi-select notes (Cmd/Shift-click) to batch move, delete, or move to another vault
• A running note, folder, and word count under the note list
• The familiar folders → notes → editor layout

• Add status, owner, due, priority, aliases, or custom keys to any note
• Edited as compact, color-coded chips
• Stored as standard YAML front matter - round-trips with Obsidian and is scriptable
• Turns prose notes into manageable items (a lightweight tracker)

• [[wiki links]] connect notes; backlinks are automatic
• Section links: [[Note#Heading]] jumps to a heading, [[#Heading]] links within the note - type [[Note# and Metis autocompletes the headings
• Hover a [[link]] on Mac to preview the target note, or just the linked section, without leaving what you are writing; on iPhone and iPad, long-press a link in Reading and pick Peek
• Insert Link offers recent notes plus a searchable picker; with words selected it keeps them as the link's label
• Edit Link Text renames what an existing link shows without touching where it goes
• Aliases let a note be linked by alternate names
• Unlinked mentions surface plain-text references with one-click linking
• A force-directed graph view visualizes the whole web, sized by connection count, with force settings (spread, link distance, gravity) to tune the layout
• Show tags turns every tag into its own node linked from each note carrying it, so tag clusters become visible shape
• The Inspector's Graph tab keeps the open note's neighbourhood - one or two hops - beside what you are writing, and follows whatever you open
• Local-graph mode focuses on a note and its neighbors (adjustable depth) with zoom and pan
• Mac: export the whole graph as a PNG (1x/2x/3x) or a vector PDF, with an optional transparent background - always the full extent, not the visible viewport

• Fast keyword search with operators: tag:, path:, title:
• On-device semantic search finds notes by meaning, not just literal words
• Private - embeddings are computed locally

• Lock any note with a password and Touch ID or Face ID - on Mac from the File menu, right-click, or Cmd-Shift-L; on iPhone and iPad by swiping the note row, its long-press menu, or the open note's ••• menu
• Locked notes are encrypted on disk and in iCloud (encrypted at rest), and a note locked on the Mac unlocks on the iPhone with the same password
• Locked notes stay out of search, Spotlight, and the link graph until unlocked
• Unlock per note or lock again from the note menu

Your password is the only key - it cannot be recovered, so choose one you will remember.

• Summarize a note; suggest tags and links
• Writing assist on a selection: continue, rewrite, fix grammar, make concise, expand
• Ask Vault: agentic Q&A that retrieves across your notes with citations
• Daily / weekly review digest; every AI feature is gated and optional

Requires an Apple Intelligence device on macOS 26 or iOS 26. The app is fully usable without it.

• Markdown checklist tasks (- [ ]) and notes carrying a due date roll up into one agenda, with task text rendered rather than shown as source
• Grouped by due date: Overdue / Today / Upcoming / Someday
• Open and Completed are two halves of one control, each carrying its own count
• A note joins the agenda by carrying a due date - a status on its own is a state, not something to do
• Scopable to a folder; toggle a task and it writes back to its source note

• Make a vault a git repo for snapshots and per-note history
• Side-by-side diffs (text and rendered) with one-click restore
• Optional auto-snapshot; uses standard git, so it is portable and CI-friendly

• Optional iCloud Documents sync across your Macs, iPhones, and iPads
• Conflict detection with a resolution UI on every platform - each conflicted note lists its versions with a preview, and the one you pick wins (Mac: File → Resolve Sync Conflicts; iPhone and iPad: Settings → iCloud)
• Files-first - your own files in your own iCloud, not a proprietary cloud
• On iPhone and iPad a vault can live On My iPhone or On My iPad instead - fully local, no iCloud account needed
• Siri Shortcuts and App Intents on iPhone and iPad: Open Today's Note and Search Notes run from Shortcuts and Spotlight

• Import individual Markdown files or whole folders recursively
• Export a note or the whole vault as Markdown, HTML (a linked static site), or JSON; reveal files in Finder
• Mac: print a note with real pagination (Cmd-P), or export it as PDF or Rich Text that opens in Pages, Word, and TextEdit with headings, emphasis, tables, and images intact
• Open With - open any note in an external app (VS Code, Typora, and more)
• Metis registers as a Markdown editor: it appears in Finder's Open With and can be made the default .md app, and in the iOS Files app's Open in / share sheet
• Plain Markdown mode edits an existing project folder in place - no front-matter injection, no renaming
• Auto-detects an existing git repo for history

• Quick switcher (Cmd-O), command palette (Shift-Cmd-P)
• Templates and daily notes - New from Template works the same on Mac, iPhone, and iPad
• Instant cold start via a persistent index
• Non-blocking activity toast showing which subsystem is working (AI / git / search)
