I replaced ChatGPT with Siri AI for a day — here's what surprised me

The author of this article experimented with using Siri AI on their iPhone for a day instead of the popular ChatGPT. They were surprised by the many ways Siri AI has evolved in iOS 27.

Firstly, Siri AI is now conversational, able to understand vague questions and context better than before. Instead of needing precise commands, the author could ask about vague topics like restaurant names or missed appointments. This improvement allowed the author to more easily find information they thought they remembered but couldn't locate.

Secondly, Siri AI can interact with what's on the user's screen. If the author was viewing information, they could ask Siri to remind them about it later or perform actions based on what they're viewing. This seamless interaction between Siri AI and the iPhone's interface makes it more useful than traditional chatbots that require extra steps to input data.

Thirdly, Siri AI excels at handling complex, everyday requests. The author gave it tasks like planning dinner based on limited ingredients or upcoming events. Unlike ChatGPT, Siri AI continued the conversation, adapting to the author's feedback and adding new constraints.

Fourthly, Siri AI has the advantage of interacting with the iPhone at an operating system level. It can perform actions based on the information it finds, something ChatGPT can't do. This gives Siri AI a unique edge in both finding and acting upon information on the device.

Finally, while Siri AI has become more useful, the author still prefers ChatGPT for brainstorming and fact-checking complex ideas. However, Siri AI has now become a go-to for when the author wants AI to help them do something on their iPhone, marking a shift in the two assistants' roles. Despite this, the author is glad Siri AI has regained relevance in their daily life.
