Getting started

  1. Choose a tool from the tools pane on the right
  2. When you move your cursor over the main pane, it will turn into a crosshair. Click on the edge of an object within the main pane to start a polygon.
  3. Move your cursor to another location along the object’s edge within the main pane
  4. Click again
  5. Continue until the object is fully enclosed
  6. Click on the starting point or double click anywhere to complete the polygon

If you make a mistake, you can remove the most recent point by clicking on it.

Zooming and panning

There are several options for controlling the zoom:

  • Press cmd/ctrl and the + and - keys on your keyboard
  • Hold Z and click your mouse to zoom in and hold alt + Z and click to zoom out
  • Click Zoom at the top right of the interface and use the slider to adjust the zoom level

There are also options to Fit (shift + 1), which will adjust the image to fit entirely within the main pane, and Actual size (shift + Z), which will display the image at its natural resolution.

You can pan the image by clicking and dragging in the main pane or by using the scrollers on your mouse.

Editing an existing polygon

With a polygon selected, you can click and drag to move any of the individual points that make up the polygon.

Create new points by hovering over a line and clicking on the smaller white dot that appears in the centre of the line. Click and drag the dot to create a new point and begin to move it.

Click on an existing point to delete it.

Creating boxes

You can quickly create a polygon box by selecting a tool, then holding down the alt or option key on your keyboard and clicking within the main pane. Move your cursor to set the box size and click again to create the box. A box is still a polygon and you can edit it as a regular polygon

Changing object classes

If you have labeled an object using the wrong class, you can change the class at any time by selecting the object and pressing C on your keyboard (or by clicking on to the right of the object in the objects pane, selecting Change class).

Hiding and deleting objects

Hide an object from view by selecting the object and pressing H on your keyboard (or by clicking Hide besides any object in the objects pane).

Hiding objects is useful when there are overlapping polygons that make it difficult to see the underlying image.

Delete an object by selecting the object and pressing delete(or by clicking next to an object in the objects pane and clicking Delete.

Leaving feedback

You can leave feedback on your current task by pressing F on your keyboard (or by clicking Feedback at the lower right of the screen). Once in the feedback pane, you can select a feedback type and leave a brief description of the problem.

If you decide to Skip the task (see the skip section for details) you will need to leave feedback.

Skipping tasks

You can click Skip at the lower right of the labeling interface to skip tasks that are not possible to complete, whether due an input data problem, ambiguous or incomplete instructions, or any other reason. You will be prompted to provide a reason for skipping. Just select a feedback type and enter a brief description of the problem before clicking Confirm skip.


Tasks that you are working on in the labeling interface autosave after 5 seconds of inactivity to protect against lost progress. It's possible to disable this feature by expanding the Options menu and sliding the Save draft automatically toggle off.
