Features
Task Tracking That Starts Fresh Every Day
Built for people who think in lists. Templates for the recurring stuff, instances for today's work, collaboration for the shared stuff. Nothing more.
Master Lists
Templates and Instances
Master List Templates
Create reusable templates for any recurring task set. Organize items into containers with up to 3 levels of nesting. Build once, stamp out working copies whenever you need them.
Instant Instance Generation
Generate a fresh working copy from any template with a single action. Deep-copies the full hierarchy of containers, items, tags, and metadata.
Daily Task Dashboard
Central view of all active list instances grouped by master list. Visual progress bars, item counts, weight totals. Archive completed lists to keep the dashboard clean.
Archive System
Archive completed instances to keep the dashboard clean. Filter between active and archived. Nothing is deleted unless you explicitly say so.
Items & Containers
Nesting, Weights, and Bulk Operations
Items with Rich Properties
Each item supports name, Markdown description, weight tracking (lb/kg), category, position ordering, color-coded tags, and check/uncheck status.
Hierarchical Containers
Group items into nested containers up to 3 levels deep. Suitcase → Toiletry Bag → Medications. Structure your lists the way you actually think about them.
Weight Tracking
Track item weights in pounds or kilograms based on user preference. Containers show total weight of contents.
Bulk Operations
Batch check/uncheck items across a list. Reorder items. Manage large lists efficiently without clicking one item at a time.
Completion Progress Tracking
Visual progress bars showing checked vs unchecked items. Weight totals update in real time. Know exactly where you stand at a glance.
Tagging
Color-Coded Organization
Color-Coded Tags
Create tags with custom names and hex colors. Attach multiple tags per item across any list. Filter search results by tag. View tag usage counts.
Collaboration
Shared Lists in Real Time
Real-Time Collaboration
Invite collaborators by email with unique 7-day access tokens. Collaborators check items off via URL with no account required. SSE pushes changes instantly.
Collaborator Access Control
Accept, revoke, or deactivate collaborator access at any time. Collaborators are read-only except for checking items. Full activity logging of who did what.
Real-Time SSE Events
Server-Sent Events stream per list instance. Events for item created, updated, checked, and deleted. Changes from collaborators appear instantly.
Search & Export
Find Everything, Take It Anywhere
Full-Text Search
PostgreSQL GIN-indexed search across master lists, instances, and items. Filter by type or tag. Paginated results.
CSV and JSON Export
Export individual list instances or all user data. Selectable fields. Full data portability.
Print-Ready Lists
Generate printable versions of any list instance. Clean formatting optimized for paper.
Import
Bring Your History With You
Things 3 Import
Upload your Things SQLite database and import your full task history. Areas become master lists, projects become instances, headings become containers, tasks become items. Tags preserved. Handles Apple Core Data timestamps and bit-packed dates. Overflow protection splits lists exceeding 1,000 items.
Drag-and-Drop File Upload
Drop your Things SQLite database directly onto the import screen. No file picker dialogs needed.
Packed Integration
Pull reusable list templates directly from Packed. Browse available lists, import with one click, and generate working instances. Dashboard has a dedicated “Add from Packed” button.
Per-User API Keys
Generate sk_ prefixed API keys for programmatic access. SHA-256 hashed in the database with timing-safe comparison. List, create, and revoke from the API.
MCP Server with 35 Tools
Full Claude Code integration covering master lists, instances, items, containers, tags, collaborators, search, Packed integration, and API key management.
Secure Authentication
RS256 JWT via auth-service. Email verification, password reset, enumeration-safe flows. AUTH_DISABLED mode for development.
User Profile Management
Weight unit preference (lb/kg), theme preference, email change with re-verification, account soft-deletion with cascade.
Responsive Design with Light/Dark Mode
Desktop sidebar navigation with mobile-friendly layouts. CSS Modules with AVIAN design system. System preference detection with manual toggle.
How It Works
From Template to Archive
Template
Create a master list with items, containers, tags, and weights. This is your reusable blueprint.
Generate
Stamp out a fresh instance whenever you need one. Everything copies over — ready to use.
Check Off
Work through your list. Check items as you go. Pull in templates from Packed. Collaborators see changes in real time via SSE.
Archive
Done? Archive the instance. Your master template stays pristine for next time.
