no-code annotation interface
Provides a visual, drag-and-drop interface for labeling data without requiring coding knowledge. Supports multiple annotation types including classification, bounding boxes, polygons, and semantic segmentation.
multi-annotator consensus scoring
Automatically calculates agreement metrics between multiple annotators on the same data samples. Identifies labeling inconsistencies and flags low-confidence annotations for review.
rest api for programmatic access
Provides programmatic access to annotation data, project management, and quality metrics through REST endpoints. Enables custom integrations with ML pipelines and external tools.
user and permission management
Manages user accounts, roles, and granular permissions across projects and datasets. Supports SSO integration and role-based access control (RBAC).
annotation analytics and reporting
Generates dashboards and reports on annotation progress, quality metrics, annotator performance, and project timelines. Includes visualizations and exportable reports.
data privacy and compliance controls
Provides features for data anonymization, encryption, access logging, and compliance with regulations like GDPR and HIPAA. Includes data retention policies and secure deletion.
inter-annotator agreement metrics
Calculates statistical measures (Cohen's kappa, Fleiss' kappa, Krippendorff's alpha) to quantify agreement between annotators. Provides detailed breakdowns by sample, category, and annotator.
collaborative annotation workflow management
Enables teams to assign annotation tasks, track progress, set deadlines, and manage workload distribution across multiple annotators. Includes role-based access control and task routing.
