Built-in Types
Every workspace includes these built-in Types. Their schema is owned by Lar, so their properties can’t be edited, but you can still set their link view, card view, and automations. Built-in Types that aren’t in your sidebar yet can be added from the Add new object type gallery under Built-in types.
To add your own structure, create a custom Type, which can extend Note or another Type; see Create and edit an Object Type.
Core knowledge Types
Section titled “Core knowledge Types”| Type | Purpose |
|---|---|
| Note | The root of every Type hierarchy; all Types, built-in and custom, inherit from it |
| Page | A plain page with a title and a rich body |
| Tag | A first-class Tag Object, created by hashtags and used for tag browsing |
| Daily Note | One date-keyed Object per calendar day |
| Query (a Saved View) | A saved query and its chosen layout |
| Collection | A hand-picked list of Objects; see Collection |
| Template | Reusable property values and body content for a Type |
| Table | A table with formatting options and formulas |
| AI Chat | An AI conversation, saved automatically when you send your first message |
Planning Types
Section titled “Planning Types”| Type | Purpose |
|---|---|
| Task | Status, priority, due date, deadline, recurrence, and blocked-by/blocks relations |
| Event | Calendar start, end, and location; the target for calendar import and sync |
Task gets its done, due, and recurrence properties from the built-in Taskable Mixin. Attach Taskable to a custom Type to make its Objects task-like.
Files and web content
Section titled “Files and web content”| Type | Specialized behavior |
|---|---|
| Image | Image viewer, dimensions, categories, colors, and text recognition (OCR) where enabled |
| File | Any uploaded file, with open and download actions |
| In-app pages, text extraction, annotations, and image extraction | |
| Audio | Playback, recording intake, and transcription where configured |
| Weblink | A saved URL with archived reader content, highlights, and previews |
| A saved email with sender, recipients, subject, and received date | |
| YouTube Video | A YouTube link with channel, duration, and publish date |
| Tweet | A Twitter/X post or thread |
| Social Post | A post from another platform, such as Instagram, Threads, LinkedIn, or Mastodon |
| Movie | A film with release year, runtime, genres, watch status, and rating |
All of these except Tweet and Movie share the built-in FileBacked Mixin, which stores technical details such as file name, size, and MIME type. Those details are hidden on the page and shown by the file’s viewer.
Automation Types
Section titled “Automation Types”- Capture holds raw content awaiting triage and tracks its processing state. See Capture.
- Workflow stores a trigger, conditions, a node graph, a mode, and whether it’s enabled. See Workflow.
Lar keeps these infrastructure Objects out of ordinary graph and search surfaces, where they’d clutter your 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 properties shared by several Types.
