Apple is preparing to turn Siri into a full chatbot-style assistant with iOS 27, giving it the ability to read what is on a user’s screen, recall personal details across conversations, and execute tasks that span multiple apps. The update, reported by Mark Gurman at Bloomberg, positions the changes as a direct response to the rapid adoption of standalone AI tools from OpenAI and Anthropic. With Apple also planning to let users swap in competing AI assistants inside iOS, the stakes extend well beyond a single software release: the company is betting that deep system-level integration can outweigh the head start its rivals already hold.
Why Apple’s Siri rewrite is a race against user habits
The urgency behind this overhaul comes down to a simple problem. Hundreds of millions of iPhone owners already have Siri on their devices, yet a growing share of them now reach for ChatGPT or Claude when they need something more than a timer or a weather check. Apple’s own developer site confirms that Siri’s personal context understanding, onscreen awareness, and in-app actions remain in development and will ship in a future software update. Every quarter those features stay unfinished is another quarter in which users build new habits around third-party AI apps that do not need Apple’s permission to improve.
The hypothesis that App Intents, Apple’s framework for letting Siri trigger actions inside third-party apps, could outpace OpenAI’s plugin ecosystem within 18 months of iOS 27’s release rests on one structural advantage: distribution. OpenAI must convince developers to build for a plugin store that users visit voluntarily. Apple can make Siri actions a default surface that appears whenever someone talks to their phone. But distribution alone has not saved Siri before. The framework has been available to developers for years, and adoption has been uneven. Whether the iOS 27 version of App Intents includes enough new capability to change that calculus is the central open question.
There is also a behavioral hurdle. Power users who have already woven tools like ChatGPT into their workflows may be slow to abandon them, even if Siri catches up on raw capability. Apple is effectively racing not just rival models, but the muscle memory of millions of people who now instinctively open a chatbot app instead of holding down the side button. Reversing that habit will require Siri to be both obviously better integrated and reliably more convenient than the alternatives.
Screen reading, memory, and cross-app control: what Apple has shown so far
Apple first outlined these capabilities at its 2024 Worldwide Developers Conference, when it introduced its broader Apple Intelligence initiative for iPhone, iPad, and Mac. The company described a version of Siri that could draw from personal context, take action across apps, and add onscreen awareness to “understand and take action with users’ content in more apps over time.” A keynote demo showed Siri pulling a photo from the Photos app and dropping it into Notes in a single conversational exchange, illustrating the kind of fluid, multi-app workflow that standalone chatbots cannot replicate without operating-system access.
Bloomberg’s reporting adds a competitive layer to those technical promises. Gurman’s account of the planned Siri revamp frames the iOS 27 update as Apple’s effort to fend off OpenAI by rebuilding the assistant as a built-in chatbot for both iPhone and Mac. A separate article in Bloomberg’s Japanese edition reports that Apple intends to let users invoke alternative AI systems through Siri, effectively turning the assistant into a front end for multiple models rather than a single, closed service. That second detail is significant: it suggests Apple views the assistant layer less as a walled garden and more as a platform play, where controlling the integration points matters more than being the only voice in the room.
The three headline features-screen reading, personal memory, and cross-app actions-each solve a different gap. Screen awareness lets Siri respond to what a user is looking at without requiring the user to copy and paste text into a chat window. Personal context means Siri can remember preferences, past requests, and relationships between contacts, files, and apps, so that follow-up questions feel natural instead of repetitive. Cross-app actions, powered by App Intents, let Siri chain together steps that today require switching between apps manually. Together, they describe an assistant that behaves less like a search box and more like a colleague who can see your screen and act on your behalf.
On paper, this combination could make Siri uniquely capable of “closing the loop” between information and action. A user might ask for flight options, pick one, and have Siri not only book the ticket but also add the itinerary to a calendar, file the confirmation email, and share the details with a travel companion-all without leaving the conversation. That kind of orchestration is difficult for web-based chatbots that lack deep hooks into the operating system, no matter how advanced their language models become.
How opening to rival assistants could reshape the platform
The plan to open Siri to competing assistants is where Apple’s strategy becomes most unconventional. According to Bloomberg’s Japanese-language coverage, Apple is preparing a mechanism for users to route certain Siri requests to external AI systems, effectively treating them as interchangeable engines behind the same voice interface. If implemented broadly, this would allow someone to keep using the familiar “Hey Siri” invocation while choosing a different model for tasks like coding help, translation, or creative writing.
For Apple, this approach offers a way to keep the assistant layer central even if third-party models outperform its own. By owning the invocation phrase, the on-screen UI, and the permissions system that governs what an assistant can access, Apple can remain the gatekeeper of the experience while acknowledging that no single model will be best at everything. It also aligns with the company’s privacy posture: routing requests through a controlled interface makes it easier to enforce data-handling rules and present clear consent prompts when assistants want access to sensitive information.
However, the competitive impact will depend heavily on implementation details. If switching to a rival assistant requires digging through nested settings, most people will never bother. If, instead, iOS offers contextual suggestions-“Do you want to use another assistant for this kind of task?”-the presence of alternatives could become much more visible. Android has long allowed users to pick a default assistant, yet Google Assistant still dominates, a reminder that defaults and discovery mechanisms matter as much as formal openness.
Gaps in the evidence and what to watch at WWDC
Several important details are still missing from the public record. Apple has not issued a formal statement confirming the iOS 27 release timeline or the specific feature set described in Bloomberg’s reporting. The company’s public materials on Apple Intelligence describe ambitious assistant capabilities but stop short of tying them to a specific OS version or date. That gap matters because Apple has a history of previewing Siri features that arrive later than expected or in reduced form.
The plan to open Siri to competing assistants appears only in Bloomberg’s coverage and has no matching language in Apple’s newsroom or developer documentation. If Apple does follow through, the practical details will shape whether the move genuinely increases competition or simply creates a setting most users never find. Android’s experience shows that technical support for choice does not automatically translate into meaningful market share for alternatives.
The next concrete milestone is Apple’s annual developer conference, typically held in June. That event will reveal whether the iOS 27 Siri update includes the full set of capabilities Bloomberg has described, whether App Intents receives the kind of expansion that would make third-party adoption worthwhile, and whether competing assistants get meaningful access or a token toggle buried in settings. For iPhone owners, the difference between those outcomes will determine whether Siri finally feels like a first-class AI companion or remains a familiar icon playing catch-up from the home screen.
