The annotation platform for biomedical AI

Turn every scan into a training-ready dataset.

LabelX is where biomedical AI teams label faster and train sooner. SAM-assisted segmentation, an active reranking loop that focuses effort where it counts, and one-click export to COCO or YOLO — so you spend less time labeling and more time shipping models.

SAM-assisted segmentation

Click once, get a pixel-perfect mask. Label an order of magnitude faster.

Every annotation primitive

Boxes, polygons, lines and circles — by pen, touch or mouse.

Active reranking loop

Train a model, then let it surface the images worth labeling next.

Vector memory

Embeddings cached in Qdrant, so re-prompting an image is instant.

Train-ready export

COCO, YOLO, LabelMe or masks — a single, versioned .zip.

Live project insight

Coverage, class balance and progress, at a glance.

Built for the teams turning imaging into clinical AI.

Pathology, radiology, microscopy, dentistry — wherever the dataset decides the model, LabelX gets you there faster.
