Quickstart
Get started with annotations in 5 minutes -- create a label, set up a queue, add items, and start annotating.
What you will do
In this walkthrough you will create an annotation label, set up a queue, add traces to it, and annotate your first item. The entire flow takes about 5 minutes.
Create an annotation label
Navigate to Annotations in the left sidebar, then open the Labels tab. Click Create Label.

Fill in the form:
| Field | Value |
|---|---|
| Name | Sentiment |
| Type | Categorical |
| Options | Positive, Negative, Neutral |
| Allow Notes | Enabled |
Click Create to save.

Create a queue
Switch to the Queues tab and click Create Queue.
| Field | Value |
|---|---|
| Name | Review Queue |
| Labels | Select the Sentiment label you just created |
| Assignment Strategy | Round Robin |
| Annotators | Add yourself |
| Annotations Required | 1 |
Click Create to save the queue.

Add items to the queue
Go to your Observe project and open the LLM Tracing view. Select one or more traces using the checkboxes, then click the Add to Queue button in the toolbar.
In the dialog, choose Review Queue and confirm. The selected traces are now queue items with a Pending status.
Start annotating
Go back to Annotations > Queues and click on Review Queue to open its detail page. Click Start Annotating.
The annotation workspace loads the first pending item. You will see:
- The trace content on the left.
- The annotation panel on the right with your
Sentimentlabel.
Select an option (e.g. Positive), optionally add a note, and click Submit.

The workspace automatically advances to the next item. You can also click Skip to move past an item you cannot annotate.
Review progress
Click the Analytics tab on the queue detail page to see completion rates, annotator activity, and label distribution.

Tip
Keyboard shortcuts speed up annotation significantly:
- Ctrl+Enter (or Cmd+Enter) — Submit the current annotation
- 1-9 — Select a categorical option by its position
- S — Skip the current item
