Add files or folders mid-session without losing staged changes.

Metadata search expands keyword queries through vocabulary synonyms. Search for a synonym and find files tagged with the canonical term. Works across browser search, smart collections, and export queries.

Detects when file keywords match vocabulary synonyms and suggests normalizing to canonical terms. Normalization badges on keyword chips with per-chip and batch normalization options.

4 built-in vocabularies with 600+ industry-standard terms: IPTC Media Topics (17 categories), IPTC Scene Codes, ISO 3166 Country Codes, and Common Keywords.

Interactive tree UI for hierarchical vocabularies with expand/collapse chevrons, descendant counts, and keyword usage badges.

Cross-vocabulary search, language filters, usage tracking, synonym display, and IPTC code references. Access via ⌃⌘V.

Import custom vocabularies from TXT, MD, CSV, or JSON with validation for duplicates, hierarchy integrity, and IPTC code format. Paste a delimited keyword list (semicolon, newline, pipe, or comma auto-detected) directly into a new or existing vocabulary, with case-insensitive merge into synonym lists. Export for sharing or backup.

Bidirectional sync: IPTC keywords write to Finder tags, captions sync to Finder comments. Batch sync with loop prevention for consistent metadata across macOS.

Built-ins (IPTC Subject, IPTC Scene, ISO Country, Common Keywords) ship read-only so MetaScope can refresh their content with each release. The Duplicate button creates a fully editable user copy with all terms, synonyms, translations, categories, IPTC codes, and hierarchical structure preserved.

A power-toggle on every vocabulary header turns it OFF without losing data. Disabled vocabularies stay in the sidebar but stop appearing in keyword autocomplete, synonym enrichment, normalization suggestions, and rule-target pickers. Existing keyword rules referencing a disabled vocabulary keep working.

The Edit Vocabulary sheet for hierarchical vocabularies splits into a Terms pane (term content edits) and a Hierarchy pane (full tree view with search, right-click reparent, and confirmation toasts). Reparent failures from cycles surface as orange toasts, successful moves as green. Scales smoothly to vocabularies with thousands of terms.

Type in keyword rule fields to get instant suggestions from all loaded vocabularies with source badges and keyboard navigation.

Advisory validation shows when rule terms match or deviate from vocabulary standards. Non-blocking hints help maintain consistency without restricting custom terms.

On-device NLP reads your description and caption text and extracts people, places, and organizations into proper IPTC fields (Persons Shown, Location Shown, Creator). Scan and preview, then accept or reject per suggestion. Configurable entity types and confidence threshold (30 to 95%), with optional geocoding validation for locations. Runs entirely on-device via Apple's Natural Language framework.

Multi-source suggestion engine combining recent terms, frequent terms, synonym matches, and vocabulary entries with weighted confidence scoring. Surfaces the right keyword as you type rather than forcing you to scroll through long lists.

Auto-generate keyword rules from IPTC vocabulary synonym mappings. MetaScope analyzes terms to create smart rules that catch variations automatically, so a single canonical keyword captures every common spelling and translation.

The submenu sorts editors by usage so the more you use a tool the higher it surfaces.

Press OPT+CMD+0 in any standalone window (Batch, Template Manager, Metadata Search, Help, Analytics Dashboard, Field Picker, Search Settings, Export Wizard, Metadata Copy, Launchpad, Exif Editor, Entity Enrichment, vocabulary windows) to animate back to default size and re-centre on screen. One API contract, future windows wired correctly by construction.

Hide/show toolbar items via Settings, three density presets (Compact, Standard, Comfortable), and right-click context menu for quick customization.

Rename files directly in the browser with slow-double-click to edit. Works in both list view and thumbnail grid with Enter to confirm and Escape to cancel.

Rate files directly from the thumbnail grid or list view. Click the star overlay, use Option+0–5 keyboard shortcuts, or pick a rating from the context menu. Writes to XMP:Rating instantly.

On macOS Tahoe, toolbars and system chrome adopt the native Liquid Glass material. Toolbar controls, filter chips, and the compare tray use glass effects. Availability-gated with no visual difference on macOS 15.

Context menus throughout the app use native macOS menus with stable submenus. Labels, Rating, and Apply Profile submenus no longer collapse when the parent view updates.

A tile grid that replaces the empty-state screen, opening common metadata tasks with a single click. Open Folder and Copy Metadata tiles sit alongside a dimmed Workbench teaser. Opens automatically when a window has no folder loaded, or on demand from Tools › Show Launchpad (⇧⌘L). Fully toggleable in Settings › Interface › Launchpad.

Right-click any image, video, or folder to drop the cached preview and regenerate from source. A content-aware cache also auto-refreshes thumbnails when a file is re-encoded at the same path.

Apple Photos, Lightroom, Aperture, Music, and TV library bundles are treated as opaque packages. A .photoslibrary opens a dedicated Info Panel with a Browse in Photos Environment CTA. Other library bundles get a Reveal in Finder action.
