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 ($…$ / $$…$$)
• Mac: tables are editable as tables as of 2.7 - Tab and Shift-Tab walk the cells, Enter adds a row, and Format → Table or a right-click inserts and deletes rows and columns, aligns a column, or tidies the block. Columns re-pad when you leave the table, not while you type, and the file stays ordinary GFM
• Mac: a column marked :---: reads as aligned in Reading and in an exported page as of 2.7, not only in the source
• Mermaid diagrams from ```mermaid fences (flowcharts, sequence, class, state, ER, gantt, pie), drawn at the diagram's own natural size - Settings → Editor picks Small / Natural / Large / Fit Width, a wide one still shrinks to fit the column, and any diagram opens full size in its own resizable window
• An Inspector column beside the note (Opt-Cmd-I): Outline maps every heading, indents by level, and jumps you anywhere in one click - in Live, Wysiwyg and Reading. As you write it follows the caret and highlights the section you are in; two sections with the same name stay distinct targets. 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. On macOS 26 a theme tints the sidebar's glass rather than covering it, so a themed window keeps the same translucency as an untinted one
• Once a note fills the window the editor keeps about a third of a screen of space beneath the last line, so the end of a long note is a comfortable place to write rather than the bottom edge - a click or tap in that space puts the caret at the end
• Optional line numbers, on the Mac and on iPad; 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
• The note list can switch to a tree view - notes nested inside their folders with counts (and folder colours on the Mac); a toggle beside search on the Mac or in the list menu on iPhone and iPad, remembered per vault
• 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
• Block links: a link can point at a single block - a paragraph, a list, a table - with [[Note#^id]] (Obsidian's convention; the ^id sits at the end of the block, so the file stays plain and the link works in Obsidian too). Right-click a block on the Mac, or long-press it in Reading on iPhone and iPad - the editor's edit menu offers Copy Link to Block too. Following the link jumps straight to that block on every platform; hover preview (Mac) shows just it
• 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: - vault-wide search on the Mac lives at Cmd-Shift-F
• On-device semantic search finds notes by meaning, not just literal words
• Private - embeddings are computed locally
• Find in the open note (Mac): Cmd-F opens a find bar over the note itself, in Live, Wysiwyg, and Reading alike - Cmd-G / Shift-Cmd-G step through matches, Cmd-E searches the selection
• Opt-Cmd-F finds and replaces in the note, one match or all, undoable (editing modes)

• 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
• Send a note's open tasks to Apple Reminders - right-click the note and pick a list, and every - [ ] becomes a reminder carrying its date and time. Write the date the everyday way (15/09/2026) or the ISO way (2026-09-15). They land in a Metis list of their own, created on iCloud, unless you pick another from the same menu. One direction only, no duplicates, and nothing is written back into your Markdown files

• 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, and a rename only when you type a new name for that note yourself
• Auto-detects an existing git repo for history

• Tabs keep several notes open at once (Mac, and iPad in regular width): a single click or tap reuses one preview tab, so browsing never piles up clutter; double-click or Cmd-Return keeps it, and on iPad long-press a note for Open in New Tab. Cmd-W closes a tab, Cmd-1..9 and Ctrl-Tab switch - hardware keyboard included. Each tab remembers its own mode (and, on the Mac, scroll position), the open set comes back the next time you open that vault, and on the Mac tabs wear their folder's colour on the top edge. iPhone keeps the one-note flow
• 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)
