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 layers of quality assurance, and supports annotation types such as bounding boxes, polygons, keypoints, segmentation, cuboids, meshes, and 3D point clouds. Listed model support includes SAM-family models, YOLO, Qwen2.5-VL, LayoutLMv3, SAM 3D, Autodistill, RLHF, and bring-your-own-model options. Teams can connect AWS S3, Google Cloud, Azure, local storage, Roboflow, and Google Vision OCR. A REST API with 110+ secure endpoints and a Python SDK cover projects, files, assignments, and exports. Export options include COCO, YOLO with tracking and attributes, and Keylabs formats. It can run in the cloud or on customer hardware, including fully on-premise deployment. Keylabs lists GDPR compliance, ISO 27001 and ISO 9001 certification, and encryption at rest and in transit. A free trial is available, but there is no free plan. Paid plans start at $1, with the listed Startup plan billed at $1,200.00.
