Ethical human-in-the-loop data labeling and AI validation
Annotation services for object detection, classification and segmentation across still images and frame-by-frame video, aimed at autonomous driving, drones and industrial inspection models.
Text extraction, intent tagging, transcription and speech dataset work to train and evaluate language, conversational and voice models.
Human feedback collection, prompt monitoring, A/B testing and output evaluation to fine-tune LLMs and correct biases in generative and agentic systems.
Independent human testing, risk evaluation and traceable evidence to help teams document and validate AI systems against regulatory requirements.

Curate, annotate and QA multimodal training data in one governed workspace
Annotate image, video, audio, text, documents, medical imaging, pathology, geospatial, sensor and tabular data in one governed workspace rather than stitching together separate tools.
Bring your own models into the labeling loop for pre-annotation, segmentation and object tracking, with multiple model stages combined with human review before anything is approved.
Consensus, Quality Gate and expert review stages validate labels against hidden answer keys to keep training data reliable — Unitlab cites 99%+ QA-backed accuracy.
Build dataset versions as data evolves, assign tasks, track changes and keep annotation history and label lineage auditable across the AI lifecycle.
