Set Scale AI task metadata from Linear comments
Important clarifications often arrive as a Linear comment and never reach the people doing the labeling. Notis captures that context and sets it as metadata on the linked Scale AI task, so the latest guidance travels with the work.
Trigger
Comment Received Trigger
Triggered when a comment is received.
Action
Set Task Metadata
Tool to set key-value metadata on an existing Scale AI task. Use when you need to attach custom metadata to track or organize tasks. This operation is idempotent.
Why this helps
Clarifying comments live in Linear while labelers work off stale task details in Scale AI.
- Fresh context reaches Scale AI tasks without copy-paste
- Labelers work from the latest instructions, not the original ones
- The metadata update is idempotent, so repeated comments stay tidy
Setup
Build it in a few focused steps.
- 1Connect Linear and Scale AI to Notis once from the portal
- 2Open your portal link and create a New Automation
- 3Describe the outcome: when a Linear comment adds context, set it as metadata on the linked Scale AI task
- 4Select the Linear Comment Received trigger and pick a reporting channel
- 5Post a test comment and confirm the metadata updates on the Scale AI task
Questions about this workflow
What if the same field is set twice?
Setting task metadata is idempotent, so re-running with the same key simply updates the value cleanly.
Does every comment trigger it?
Only the ones you describe. You can tell Notis to act only on comments that add labeling context.

Supported Triggers and Actions
Notis builds workflows that link Linear to Scale ai. A trigger fires from one place; an action lands in another.
Linear triggers
Scale ai actions
Comment Received Trigger
Triggered when a comment is received.
Add Studio Assignments
Tool to add project assignments to team members in Scale AI Studio. Use when you need to assign specific projects to team members by their email addresses. This action creates new assignments for the specified team members and projects.
Issue Created Trigger
Triggered when a new issue is created.
Add Task Tags
Tool to add tags to an existing task. Use when you need to tag or categorize tasks for organization and filtering. Automatically avoids duplicate tags.
Issue Updated Trigger
Triggered when an issue is updated. For example labels are changed, issue status is changed, etc.
Create Batch
Tool to create a new batch within a project. Use when you need to group multiple tasks together for organizational and processing purposes.
Private Team Comment Created
Fires when a new comment is posted on an issue in a private Linear team (polled with the connected user's token).
Create Document Transcription Task
Tool to create a document transcription task where workers transcribe and annotate information from single or multi-page documents. Use when you need to extract structured data from documents like invoices, forms, or screenshots.
Private Team Issue Created
Fires when a new issue appears in a private Linear team (polled with the connected user's token).
Create Image Annotation Task
Tool to create an image annotation task where annotators label images with vector geometric shapes (box, polygon, line, point, cuboid, ellipse). Use when you need to annotate objects in images with bounding boxes, polygons, or other geometric annotations.
Private Team Issue Properties Updated
Fires when properties on an issue change in a private Linear team (polled with the connected user's token).
Create Lidar Annotation Task
Tool to create a lidar annotation task where annotators mark objects with 3D cuboids in 3D space. Use when you need to annotate LIDAR frame sequences with 3D object detection.
Project Created
Fires when a new Linear project is created. Covers projects in both public and private teams — polls with the connected user's token, so visibility matches what the connected user can see in Linear.
Create LiDAR Segmentation Task
Tool to create a LiDAR segmentation task where annotators assign semantic class labels to individual LiDAR points. Use when you need to annotate point cloud data with object classes such as vehicles, pedestrians, roads, buildings, etc. Either 'project' or 'batch' must be provided in the request.
Project Properties Updated
Fires when properties on a Linear project change (status, lead, target date, priority, etc.). Covers projects in both public and private teams — polls with the connected user's token.
Create Named Entity Recognition Task
Tool to create a named entity recognition task for labelers to highlight text entity mentions. Use when you need to extract and label entities such as people, organizations, or locations from text.
