+## Demo Video: Similarity Search UI
+This short video showcases the **EchoPrime similarity search user interface**, a companion tool that enables interactive retrieval of echocardiogram studies based on cosine similarity.  
+It demonstrates how users can query specific phrases (e.g., *aortic root dilation*, *mitral calcification*) or upload new studies, and view the most similar cases across multiple views in real time.
