Encord

Multimodal data labeling and curation for production AI

paidupdated Apr 21, 2026

Encord is a data labeling and curation platform for teams building production AI systems with complex multimodal data. It supports image, video, audio, DICOM medical imaging, and 3D point cloud annotation with AI-assisted labeling, advanced ontology management, and quality assurance workflows. Features active learning for prioritizing high-value samples and integrates with major ML frameworks.

Encord provides enterprise-grade data labeling infrastructure for teams working with complex, multimodal datasets. The platform handles annotation types ranging from standard bounding boxes and segmentation masks to specialized formats like DICOM medical imaging, 3D LiDAR point clouds, and video timeline annotations. AI-assisted labeling uses model predictions to pre-annotate data, with human reviewers correcting and validating results — significantly reducing the manual effort required for large-scale dataset creation.

The ontology management system enables teams to define and enforce consistent labeling schemas across projects and annotators. Quality assurance features include consensus scoring across multiple annotators, review workflows with approval gates, and automated quality metrics that identify labeling inconsistencies. Active learning integration helps teams prioritize which samples to label next based on model uncertainty, maximizing the impact of each annotation on model performance.

Encord serves teams building AI systems in healthcare, autonomous vehicles, robotics, and other domains where data complexity and annotation precision are critical. The platform provides Python SDK access for programmatic dataset management, exports to major training frameworks, and supports both cloud-hosted and on-premises deployment for data-sensitive environments. For organizations where dataset quality is the primary constraint on AI system performance, Encord provides the specialized tooling needed for high-precision multimodal data curation.
