Echo is a Windows desktop application that provides offline semantic image search using CLIP embeddings and FAISS indexing. It combines a C# WinForms frontend with a Python FastAPI backend, offering a global hotkey, live folder management, and filesystem watching for automatic indexing. The project is notable for its practical integration of modern ML models into a native-feeling desktop tool with full local privacy.
