Siri
What Does Siri Do?
Siri is Apple's intelligent personal assistant, integrated across Apple's ecosystem including iOS, iPadOS, watchOS, macOS, tvOS, and HomePod. It uses voice queries and a natural language user interface to answer questions, make recommendations, and perform actions by delegating requests to a set of Internet services. Siri adapts to users' individual language usages, searches, and preferences, with a focus on privacy through on-device processing for many tasks and end-to-end encryption for server-based queries.
