Annotation studio for biomedical imaging
Nothing in biology
makes sense except in the light of data.
LabelX turns pathology slides, OPGs, CT and microscopy into pixel-perfect, model-ready datasets — with SAM 2 segmentation, vector memory, and an active-learning loop that tells you what to label next.
