Annotation services
Training data your model can actually trust
Spec-driven, human-labelled datasets with two-pass QA — from simple bounding boxes to pixel-level segmentation and 3D cuboids.
Bounding Box Annotation
2D boxes for fast, reliable object detection training data.
From $0.03 / box →
Polygon Annotation
Pixel-tight outlines for irregular, overlapping objects.
From $0.09 / polygon →
Semantic Segmentation
Pixel-level class labels across the whole scene.
From $1.20 / image →
Keypoint & Landmark Annotation
Pose, face and skeleton points placed with precision.
From $0.06 / point →
3D Cuboid Annotation
Depth-aware boxes for spatial and autonomy datasets.
From $0.18 / cuboid →
Image Classification & Tagging
Clean taxonomies and consistent tags across huge datasets.
From $0.02 / image →
