Labelbox serves as a browser-first training data platform, specifically engineered for computer vision teams to manage the entire lifecycle of their annotation projects. It enables ML engineers and data scientists to upload raw image, video, and sensor data, define precise labeling ontologies, distribute annotation tasks to human labelers, conduct robust quality assurance, and export high-quality, structured datasets directly usable for model training and validation. The platform streamlines the often-complex process of data preparation, acting as the central web interface for transforming unstructured visual data into actionable ground truth for AI development.

Use Cases
Accelerating Model Iteration with High-Quality Dat
ML engineers and data scientists leverage to rapidly generate and refine labeled datasets for training and validating new computer vision models. This allows them to quickly iterate on model architectures and performance by ensuring a continuous supply of precise ground truth data, directly addressing data bottlenecks in the development cycle
How to Use Labelbox
Ingest Data and Define Ontology
Navigate to the web application, sign in, and create a new project. Upload raw image, video, or sensor data assets directly through the browser or via cloud storage integrations. Then, use the ontology editor to define the specific object classes, attributes, and annotation types (e.g., bounding box, segmentation mask) required for your computer vision task
