What is PySyft?

PySyft lets you perform data science and machine learning on data that stays on its owner's server, eliminating the need to copy or expose raw data. It provides a Pythonic interface that integrates with PyTorch and other ML frameworks for secure, privacy‑preserving computation. Built by the OpenMined community, PySyft supports federated learning, differential privacy, and multi‑party computation, enabling collaborative AI while respecting regulatory and IP constraints.
