Demo setup
Set up your annotation demo.
Choose a task, define labels, and start fresh. Everything runs in your browser — no images leave your device.
Temporary demo — not saved unless you sign in.
This sandbox runs only in your current browser tab. No previous demo, label set, or annotation is restored from anyone else who has used this browser. Closing the tab wipes the work.

The canvas adapts to the task: object detection shows bbox tools, classification hides them, segmentation enables polygons.
