ISO 27001 data annotation services for AI and ML teams in regulated industries
Bounding boxes, polygons, segmentation masks, keypoints, landmarks, and classification labels for detection, segmentation, and classification models, with human validation on every batch.
Frame-by-frame boxes, masks, keypoints, and identity-consistent object tracks for detection, tracking, and action-recognition models, validated at the sequence level.
3D cuboids, point cloud segmentation, drivable-area labeling, and object tracking for robotics, autonomous mobility, geospatial, and industrial AI programs.
Text-region labeling, document segmentation, handwriting annotation, structured field extraction, plus LLM evaluation with calibrated rubrics and GenAI alignment data.
Self-hosted AI workspace for local and cloud models
Connect local runtimes like Ollama alongside OpenAI-compatible and Anthropic APIs, and switch between them inside one interface.
RAG over your own documents, web search and citation-aware answers come standard, so responses are grounded in real sources.
Extend the platform with Python code to add custom tooling, preprocessing, and multi-step pipelines, then share them with others.
SSO, RBAC, audit logs, data residency, and on-premises, hybrid or air-gapped deployment for organisations with strict requirements.
