T-Rex Label is a browser-based image annotation tool built on the T-Rex2 open-set detection model. Point it at one example and its visual-prompt, zero-shot detection finds and labels matching objects across an entire dataset—no training or fine-tuning required—handling dense, occluded, and varied-lighting scenes. It exports to COCO and YOLO formats and integrates with tools like Roboflow and Labelbox.

Pros & cons

  • Zero-shot, no training needed
  • Batch-labels from one example box
  • Handles dense and occluded scenes
  • COCO and YOLO export
  • Integrates with Roboflow, Labelbox
  • Browser-only, no offline mode
  • Pricing not clearly published
  • Detection-focused (boxes and masks)

    Vision MLOps end-to-end. Annotate, train, deploy.

    Annotation tooling, auto-labelling, hosted training, and edge deployment for computer-vision projects. Strong default when you're shipping a custom vision model rather than reaching for a multimodal LLM.

    Data platform to curate, label, and manage AI training data.

    An enterprise data development platform for preparing high-quality training data across images, video, documents, audio, DICOM, and 3D point clouds. It pairs AI-assisted labeling (SAM auto-segmentation, object tracking) with data curation, model evaluation, and workflow tooling, plus LLM-powered data agents for document tasks. Used heavily in medical imaging, robotics, and other physical-AI domains.

    Labelbox

    Data factory for AI teams — labeling, evals, and human data for training.

    Labelbox is a platform for generating and managing training data for AI models, combining annotation tools (Annotate), data curation (Catalog), and model-assisted labeling and evaluation (Model Foundry). It now spans reinforcement-learning data, custom evals, robotics datasets, and an on-demand network of expert human labelers, metered by a usage-based Labelbox Unit (LBU).
