The all-in-one computer vision platform for labeling, training and deploying vision AI
Speed up data prep with auto-annotation, model-assisted labeling, pixel-precise segmentation tools and consensus/approval workflows for consistent quality across annotators.
Build training workflows in a drag-and-drop interface, tune architecture, batch size and epochs, and visually evaluate model performance against ground truth.
Train classification, object detection, keypoint and segmentation models to cover tagging, tracking, pose estimation and pixel-level analysis use cases.
Ship models to edge or cloud environments via hosted APIs, with monitoring, scaling and secure authentication for production inference.
Enterprise AI training data, annotation and evaluation services
A large selection of ready-to-use, ethically sourced datasets across audio, image, video, text and multimodal formats, with advanced filtering and free samples.
Expert-verified labeling for text, audio, image and video using model-first, human-in-the-loop workflows for accuracy and fairness.
High-quality multilingual content for global AI systems, drawing on 500+ languages, dialects and locales.
Global, diverse data collection at scale for training, with privacy and security vetting on every dataset.
