About Labelbox

Labelbox is a platform that enables teams to annotate, manage, and curate training data for machine learning models. It provides tools for image, video, text, and document labeling alongside workflows for managing human annotators. The platform also includes features for model evaluation and active learning to improve AI development cycles.

Labelbox is a data-centric AI platform designed to help organizations create, manage, and iterate on the training datasets needed to build machine learning models. It supports a wide range of data types including images, video, text, audio, geospatial data, and documents, making it applicable across industries such as autonomous vehicles, healthcare, retail, and technology. The platform provides a suite of annotation tools that allow teams to label data with bounding boxes, polygons, segmentation masks, entity recognition tags, and more. Users can manage annotation workflows internally or route work to external labeling workforces. Quality assurance features, including review queues and consensus scoring, help maintain data accuracy. Labelbox includes capabilities for model-assisted labeling, where pre-trained models generate initial predictions that human annotators then review and correct. This approach is intended to reduce labeling time and cost. The platform also supports active learning workflows, helping teams prioritize which data samples are most valuable to label next based on model uncertainty. The platform is built for data science teams, ML engineers, and operations teams at companies developing AI products. It integrates with major cloud storage providers and machine learning frameworks, and offers an API for programmatic access. Labelbox competes with tools such as Scale AI, CVAT, and Roboflow in the data labeling and MLOps space. Pricing is not publicly listed for most tiers and is typically discussed with a sales team, though a limited free tier is available. Labelbox positions itself as an enterprise-grade solution emphasizing scalability, collaboration, and the full data pipeline from raw data to model-ready datasets.
