What Labellerr is

Labellerr is a data labeling and annotation platform for teams preparing training data for AI and machine-learning projects. It supports image, video, PDF, text, and audio projects, with image formats including JPG, JPEG, PNG, BMP, and TIFF. Annotation tools cover bounding boxes, polygons, polylines, keypoints, dots, classification, segmentation, and object detection. Labeling options include prompts, model assistance, and active learning; the company also says it natively supports Meta’s SAM, SAM 2, and SAM 3. Teams can use a Python SDK to manage datasets and workflows in ML pipelines, then export annotations in formats including COCO JSON, YOLO, Pascal VOC XML, CSV, and custom formats. The free Researcher Plan includes 2,500 data credits, one seat, one workspace, and up to 10 projects. Pro costs $9,999 a year and includes 100,000 data credits and up to 200 seats. Unused data credits do not carry forward to the next payment cycle.
