Apple is getting ready to relaunch Siri as a full-blown standalone chatbot app in iOS 27, and privacy is its biggest selling point. According to Bloomberg's Mark Gurman, the new Siri app will let users automatically delete conversation history after 30 days, one year, or keep it forever. That's the same set of options already available in the Messages app, and it goes further than what most rival chatbots offer. ChatGPT and others typically only provide a temporary "incognito" mode as an optional toggle. Apple wants these protections baked in by default.The app itself will work much like ChatGPT: a repository of past conversations, the ability to start fresh chats, upload files, and use voice. Users can also choose whether the app opens to a grid of past conversations or a blank new chat each time.Apple is leaning on Google to power the very thing it's calling privateHere's the twist. While Apple is pitching this as a privacy-first AI experience, it's quietly running the new Siri on Google's Gemini models. Apple says it will process these requests through its own Private Cloud Compute infrastructure—meaning Google shouldn't be training on your conversations—but the company has been vague about exactly how that arrangement works at scale.Gurman suggests Apple's privacy framing may also be doing some heavy lifting as cover for Siri's continued shortcomings. Compared to what Google just demoed for Android 17—AI deeply woven across apps, capable of completing real tasks—Apple is still playing catch-up.Even after a two-year delay, Siri could still ship as a betaPerhaps the most telling detail: internal Apple test builds of iOS 27 already label the new Siri as a "beta," with an option to opt out entirely. Given WWDC is just weeks away in June, that beta label may well stick when iOS 27 ships publicly this fall. It's a humbling position for a feature that was originally promised back in 2024.A Genmoji upgrade—suggested emoji generated from your photos and common phrases—is also planned for iOS 27.
