Apple is transforming Siri into a more open, conversational assistant in iOS 27, allowing third-party AI chatbots like ChatGPT to respond alongside Apple’s own system, marking a significant shift towards flexible, chatbot-based interactions.
Apple’s iOS 27 appears to be moving Siri closer to an open assistant model, with third-party chatbots such as ChatGPT able to take over certain text-based queries. Geeky Gadgets said the feature is designed for users who want more detailed, conversational responses than Siri typically provides, while still keeping Apple’s own assistant available for system-level tasks.
According to MacRumors, Apple is also rebuilding Siri itself for iOS 27, with a more chatbot-like experience, a dedicated app and a stronger focus on conversational interaction. That wider overhaul suggests the ChatGPT option is part of a broader push to make Apple Intelligence more flexible rather than a simple bolt-on feature.
MacRumors reported that Apple plans to let users choose third-party AI services through an Extensions area in iOS 27 settings. That would allow services such as ChatGPT, Claude or Gemini to respond inside Siri in a similar way, while Apple also reportedly works on its own model partnerships, including a Gemini-based system for some Apple Intelligence features.
In practical terms, the setup described by Geeky Gadgets is straightforward: enable the extension in Settings, sign in with a ChatGPT account, and then select ChatGPT when making a text query through Siri or Spotlight Search. The main limitation is that Siri remains better integrated with iPhone and iPad functions such as alarms, reminders, calls, messages and HomeKit controls.
Reporting from iDownloadBlog and the MacObserver adds an important caveat: switching between Siri and ChatGPT does not appear to carry conversation context across, and the selection may revert to Siri when the app is closed and reopened. Even so, the arrangement gives users a clear choice between Apple’s system control and ChatGPT’s stronger language handling, which may prove more useful for drafting, brainstorming and other text-heavy work.
