Answer
AOT compiles Angular templates during build time for faster startup, smaller bundles, earlier error detection, and better security.
AOT is the default for production builds in modern Angular.
Quick Answer
AOT compiles Angular templates at build time on the developer's machine, not at runtime in the browser. Benefits: faster app startup (browser runs pre-compiled code), smaller bundle size (Angular compiler not included in the bundle), template errors caught early, and better security (HTML/JS injection not possible since templates are pre-compiled). Default in production builds.
