Every kind of training data, labeled to your spec
We work in your tool or ours, follow your guideline to the letter, and ask before we guess. Jump to a data type below.
Image annotation

- 2D bounding boxes
- Tight, axis-aligned or rotated boxes with occlusion and truncation flags.
- Polygons & instance masks
- Vertex-precise outlines for irregular objects, crops, lesions and parts.
- Semantic segmentation
- Every pixel assigned a class, with consistent boundaries between neighbours.
- Keypoints & skeletons
- Body pose, face landmarks, livestock and custom skeletons with visibility states.
- Classification & tagging
- Single- and multi-label image tags, attributes and quality filters.
- OCR & document fields
- Text transcription and key–value extraction from receipts, IDs and forms.

Output formats
