Built-in Types
Built-in Types give common content specialized behavior. Custom Types can extend the Note taxonomy and compose reusable Mixins, but system definitions can be read-only where Lar relies on their shape.
Core knowledge Types
Section titled “Core knowledge Types”| Type | Purpose |
|---|---|
| Note / Page | General writing and the root of the user-facing Type hierarchy |
| Tag | First-class keyword Object used by hashtags and tag browsing |
| Daily Note | One date-keyed Object per day |
| Saved View / Query | Stores a query and selected layout for reuse |
| Template | Reusable structured properties and body content |
| Chat Thread | A saved AI conversation |
Planning Types
Section titled “Planning Types”| Type | Purpose |
|---|---|
| Task | Completion, due date/time, recurrence, occurrences, and Task views |
| Event | Calendar start/end, location, and calendar import/sync target |
Task behavior is also represented by a reusable Taskable Mixin, allowing an appropriate custom Type to participate in task workflows.
Files and web content
Section titled “Files and web content”| Type | Specialized behavior |
|---|---|
| Image | Image viewer, metadata, OCR/analysis actions where enabled |
| File | Generic attachment storage and open/download actions |
| In-app pages, text extraction, annotations, and image extraction | |
| Audio | Playback, recording intake, and transcription where configured |
| Weblink | Archived reader content, highlights, previews, and analysis |
Additional specialized built-ins and presets can include Email, YouTube/social content, Movie, and other content recipes. Availability can depend on the current build and enabled integration or Workflow catalog.
Automation Types
Section titled “Automation Types”- Capture holds raw content awaiting triage and tracks its processing state.
- Workflow stores a trigger, conditions, node graph, mode, and enabled state.
These infrastructure Objects are deliberately filtered from ordinary graph/search surfaces where showing them would clutter user content.
Custom Types versus built-ins
Section titled “Custom Types versus built-ins”Create a custom Type when a category needs its own properties, relations, layouts, or templates. Use a Tag for a cross-cutting topic, a Collection for a curated group within a Type, and a Mixin for structure shared by Types.
