Apple’s new Siri may dominate on installed base with iOS 27, but ChatGPT still leads on conversation
Apple is expected to roll out a revamped Siri in September alongside iOS 27, instantly giving it the largest installed base of any AI chatbot because the assistant will ship preloaded on hundreds of millions of iPhones, including devices going back to the iPhone 15 Pro. But a hands-on test by Bloomberg reporter Natalie Lung found that scale does not automatically translate into stronger chat performance. According to the report, the new Siri’s edge comes from device awareness. It can read emails, messages, notes and files stored on the phone, and it can also understand what is currently shown on screen. That allows it to generate more tailored responses and help with items such as spreadsheets, documents or even crossword clues. The trade-off is setup time: Apple’s assistant may need hours or even days to re-index device content before it can retrieve older information reliably. The report also says Siri still lacks access to real-time data from third-party apps, while ChatGPT already offers broader external integrations. OpenAI, for its part, is pushing ahead on voice interaction and productivity tools. Bloomberg highlighted GPT-Live for more natural spoken exchanges and ChatGPT Work for integrations with Codex, Google Drive and desktop workflows. In short, the comparison is shaping up as distribution versus capability: Apple has the channel, while OpenAI still holds the lead in conversational fluency and workflow breadth.
