From bounding boxes to RLHF preference ranking, AnnotRift provides every tool you need to create high-quality training data at scale.
Browser-based annotation environment with 20+ tool types including bounding boxes, polygons, segmentation masks, keypoints, and cuboids.
Multi-stage review workflows with consensus scoring, inter-annotator agreement metrics, and automated quality checks.
Access 1.5M+ vetted annotators worldwide or bring your own team. Intelligent task routing matches skills to projects.
Accelerate annotation 5x with AI-assisted pre-labeling. Your models generate initial predictions, human annotators refine them, and the feedback loop continuously improves both model and data quality.
Define complex label hierarchies, relationships, and validation rules with our visual ontology editor. Support for nested taxonomies, conditional attributes, and cross-label constraints.
Native support for all major data formats with specialized tooling for each modality.
