“The annotators were really quick. I would upload and 5 minutes later - 10 images done. I checked 5 minutes later - 100 images done.”
“The best interface for self-service labeling. Everything from uploading data to seeing it labeled in real time was really cool. This is just way simpler to use compared to Amazon Sagemaker and LabelBox.
Glad you asked! Send us a test batch of data. We’ll run the project and add you as a collaborator for you to view the results. Send us a test batch of data to get started.
Our trained annotators will label your data (after undergoing a stringent series of training courses and assessments, of course). They are remote annotators who work part-time on different projects available via our platform. Annotators are assigned to projects automatically once they are qualified for the tasks.
Currently, we only support COCO JSON output format. We'll be introducing other output formats soon. If you require another output format, drop us a message here.
Our annotators will start labeling your data as soon as you start a project. One of our users received annotated images with around 2,500 annotations in less than 2 hours. Note: turnaround time varies according to the complexity of the project.
Before you start, provide clear labeling instructions so our annotators understand how to label your images accurately. Our annotators will also help you surface label noise through our built-in collaborative feedback loop.
Your data is only visible to human labelers throughout the labeling process. We will not share or use your data for any reason other than the labeling.
