What Keylabs is

Keylabs is a data annotation platform for image, video, and 3D data. It combines AI-assisted labeling with workflow controls and multiple quality-assurance layers. Annotation options include bounding boxes, polygons, polylines, keypoints, semantic and instance segmentation, rotating boxes, skeletal data, cuboids, meshes, 3D point clouds, bitmasks, and custom annotations. Listed model support includes SAM-family models, YOLO, Qwen2.5-VL, LayoutLMv3, SAM 3D, Autodistill, RLHF, and bring-your-own models. The service connects with AWS S3, Google Cloud, Azure, local storage, Roboflow, and Google Vision OCR. Its REST API has 110+ secure endpoints, and a Python SDK manages projects, files, assignments, and exports. Exports include COCO, YOLO, native Keylabs format, and ZIP archives with JSON and PNG masks. Keylabs runs in the cloud or on customer hardware, including fully on-premise deployments. It offers self-service use or managed annotation teams.
