• The data you upload will be processed as tasks to be labelled.
  • 1 task represents a single image that requires labelling.

Labels and attributes

  • A label is an instance or class associated with your dataset.
  • An attribute* (also known as a feature) is an aspect of a label.

For example:


Image credit: Blue Clover Rabbitry

Label: Rabbit
Attribute: Breed – Mini Holland Lop*

*nested attributes are coming soon to bolt.


  • A labeller is someone who annotates tasks for you according to the instructions you’ve set.
  • Our labellers come from around the world and go through rigorous data labelling training on our platform.

Task queue

  • Once project set-up is complete, images are sent to a task queue in preparation for labellers to annotate them according to your instructions.
