iOS 27: Replace Siri with ChatGPT, Claude, or Gemini

Apple's iOS 27 will allow users to replace Siri with other AI services like ChatGPT, Claude, or Gemini. This marks a major change for Siri, which debuted over a decade ago. This feature, called Extensions, was announced during WWDC 2026. It's part of Apple's broader Apple Intelligence strategy. Currently, Siri already hands certain requests to ChatGPT, a capability introduced with iOS 18.2. However, with iOS 27, this exclusive relationship is expected to end. What's interesting is that Apple has over 2.35 billion active devices worldwide. This move could create a huge distribution opportunity for companies building generative AI assistants. Users will be able to choose their default AI provider through a simple settings change after installing a supported app. Apple is also testing more detailed controls. This would let users assign different AI services for different tasks. For example, someone could use Gemini for web research and Claude for writing. Each provider is also expected to have a distinct voice. The bottom line is Apple seems to be positioning the iPhone as a hub for multiple AI models. This means users will have more choice in how they interact with AI on their devices.
