Whole-slide imaging (WSI) for pathology education

Eosin is an open-source whole-slide imaging viewer for digital pathology under Sable Crest Labs. It’s built for pathology students and educators who need consistent, browser-based access to whole-slide images.

Use Eosin to navigate WSI quickly, add structured WSI annotation, and share permalinks that open to a specific field of view for teaching and guided study.
