Field notes
The interface accepts one ovarian ultrasound image, warns against collages and webpage screenshots, and provides a confirmation step before analysis. It says computation happens in the browser and offers a PDF export; the output separates normal-pattern and abnormal-pattern visual similarity scores. Cathra identifies PCOSGen data under CC BY 4.0 and says the demonstration is not FDA-cleared or intended for medical decisions.
