Labelbox

Labelbox is a data-centric AI platform for creating and managing training datasets - providing annotation tools for images, video, text, documents, audio, and geospatial data alongside model-assisted labeling and dataset management for ML teams. AI capabilities include model-assisted labeling that uses existing ML models to pre-annotate data and dramatically reduce human labeling effort, AI-powered quality assurance that identifies inconsistent annotations and flags labeler errors, intelligent active learning that selects the most informative unlabeled examples for annotation to maximize model improvement per labeled sample, automated data insights that surface class imbalances and edge cases in training datasets, and LLM fine-tuning data workflows that streamline the creation of instruction and preference datasets.

Labelbox is an established data annotation platform that has integrated model-assisted pre-labeling, AI quality assurance, and intelligent active learning into a mature ML training data management product.
