To opt out of Apple Intelligence and go back to the standard, AI-less experience, navigate to Settings > Apple Intelligence & Siri and flip off the Apple Intelligence toggle at the top of the page.

Apple has kicked off iOS 18.3, iPadOS 18.3, and MacOS 15.3 with one significant change affecting AI. Since its debut, Apple Intelligence has required the extra step of actually turning it on or opting in. But with the new versions, Apple's AI feature is enabled by default for eliglble devices.

If you're not sure whether you want Apple Intelligence on your iPhone, the next iOS update has it automatically switched on.As we reported in January, Apple's AI features will default to active when you install iOS 18.
