Data Annotation
Services
Precision annotation at any scale, image, video, text, and audio, with multi-layer QA built into every project.
What We Offer
Our annotation teams combine domain expertise with structured quality assurance to deliver training-ready labeled data. We handle every annotation type across every data modality, with detailed quality reports at every milestone.
Image Annotation
Bounding boxes, polygons, segmentation masks, keypoints, landmarks, and classification labels for images.
Video Annotation
Frame-by-frame object tracking, temporal segmentation, action labeling, and interpolation-based annotation.
Text Annotation
NER tagging, sentiment labeling, intent classification, coreference resolution, and relation extraction.
Audio Annotation
Speech transcription, speaker diarization, emotion labeling, sound event detection, and audio classification.
OCR Annotation
Text region detection, line-level and word-level transcription, and layout analysis for document AI.
QA Review
Multi-stage quality review including consensus checking, expert review, calibration sessions, and audit reports.
Annotation Formats We Support
Bounding Boxes
2D and 3D bounding boxes for object detection datasets across any object category.
Polygons
Precise polygon outlines for irregular shapes where bounding boxes aren't accurate enough.
Segmentation Masks
Pixel-perfect semantic and instance segmentation for dense prediction tasks.
Keypoints and Landmarks
Skeleton pose estimation, facial landmark detection, and part-level localization.
Classification Labels
Single and multi-label image/text classification with confidence scoring.
Lidar and 3D Annotation
3D bounding box annotation for point cloud data from lidar and depth sensors.
Our Quality
Framework
Quality isn't a checklist, it's built into our annotation workflow at every step through structured review, calibration, and QA processes.
Clear Guidelines
Detailed annotation guidelines with edge case coverage before any labeling begins.
Calibration Sessions
Regular calibration to align annotators on ambiguous cases and maintain consistency.
Multi-Stage Review
Peer review, lead review, and expert spot-checks at defined project milestones.
Quality Reports
Detailed IAA scores, accuracy metrics, and rejection rates reported with each delivery.
