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.

Moonshot AI's long-context assistant for research, coding, and agentic work
Feed in lengthy documents, papers, or code and ask questions across the full text without losing earlier context.
Hand over multi-step jobs that involve planning, browsing, and tool use instead of only single-turn answers.
Generate structured research reports, slide decks, and formatted documents directly from your prompt or source files.
Extend capabilities with plugins and set recurring jobs so the assistant keeps working between sessions.
