About T-Rex Label
T-Rex Label is a browser-based platform designed for B2B teams building computer vision training datasets across industries such as healthcare, automotive, robotics, agriculture, and logistics. The tool streamlines the annotation process by offering AI-assisted labeling and pre-annotation using built-in visual models like Grounding DINO, DINO-X, and T-Rex2 without requiring fine-tuning. It supports 2D bounding box and mask (segmentation) annotations for common detection and segmentation workflows, enabling efficient labeling of objects in images. A key feature is visual prompt-based object detection, where users can draw a bounding box to find similar objects across images, including cross-image inference to apply prompts consistently. The platform ensures compatibility with standard dataset formats, allowing seamless import and export of COCO and YOLO files for downstream training pipelines. T-Rex Label emphasizes one-step, in-browser prompting paired with open-set, zero-shot detection capabilities in T-Rex2, which recognizes objects beyond initial training sets without retraining, reducing manual effort for rare or long-tail classes. This approach is particularly useful for teams needing scalable, efficient, and accessible annotation workflows without heavy infrastructure dependencies.
