WWDC 2026 Preview: iOS 27, Siri 2.0, and the End of ChatGPT’s Siri Monopoly

WWDC 2026 runs June 8 to 12, with the keynote on Monday June 8 at 10am Pacific Time, streamed online globally and capped by an in-person event at Apple Park. Apple confirmed the dates and AI focus on March 23, 2026, and the company’s own teaser graphic has already hinted at a redesigned Siri.

This year’s conference is the most consequential AI moment Apple has had since Apple Intelligence debuted in 2024. Bloomberg, MacRumors, and 9to5Mac all report that iOS 27, iPadOS 27, and macOS 27 will introduce a new Extensions system for piping Siri queries into third-party AI assistants like Claude and Gemini, with the door open to Grok and others. The change ends OpenAI’s exclusive Siri integration.

Below: what is confirmed by Apple, what is leaked through credible reporters, and what is still rumor. Plus what it all means if you actually use AI on your Mac or iPhone.

The Key Takeaways

• WWDC 2026 keynote: Monday, June 8, 2026 at 10am PT (1pm ET / 6pm UK), streamed online with an in-person event at Apple Park.
• Apple is opening Siri to Claude, Gemini, and other third-party AI through a new Extensions system in iOS 27, iPadOS 27, and macOS 27, first reported by Bloomberg on March 26, 2026.
• Siri 2.0 gets a chatbot-style redesign with Dynamic Island integration, a dedicated Siri app, conversation history, and multi-step task handling across apps.
• iOS 27 is being treated as a Snow Leopard-style release by Mark Gurman, focused on stability and performance over a long feature list, but it still drops support for iPhone 11, 11 Pro, 11 Pro Max, and iPhone SE (2nd gen).
• Hardware rumors include M5 Mac mini, M5 iMac, and M5 Ultra Mac Studio, plus iOS 27 multitasking that prepares for the foldable iPhone in September.

When is WWDC 2026? Date, Keynote, and Format

WWDC 2026 runs from June 8 to June 12, 2026. The keynote starts on Monday, June 8 at 10am Pacific Time, which is 1pm Eastern, 6pm UK, and 7pm Central European Time. Apple is streaming the entire conference online for free, and an invited group of developers and students will watch the Keynote and Platforms State of the Union live at Apple Park on June 8.

The format mirrors recent years. The conference is hybrid, online globally with over a hundred video sessions and interactive labs throughout the week, plus the one-day in-person celebration. Apple’s official confirmation says the event will spotlight “incredible updates for Apple platforms, including AI advancements and exciting new software and developer tools.” That is unusually direct AI signaling from a company that has historically been quiet about machine learning until showtime.

What Apple Has Confirmed About WWDC 2026

Apple has confirmed a short list of facts and left the rest to leakers. The company has officially announced the dates, the keynote time, the hybrid format, the in-person Apple Park event, and the AI focus. Apple’s own promotional graphic teased a redesigned Siri interface, with MacRumors reporting that the swirling cursor and glow effect in the artwork match leaked details about the new Dynamic Island integration.

The OS lineup is also implicit but confirmed by Apple’s developer page. Expect iOS 27, iPadOS 27, macOS 27, watchOS 27, tvOS 27, and visionOS 27. The version-number alignment is intentional, Apple unified version numbers last year starting at 26 so all platforms share the same number going forward. Anything beyond this list, including specific Siri features, hardware refreshes, and the Extensions system, is still in leak territory and worth treating as such until June 8.

Siri 2.0: The Biggest iOS 27 Story

The Siri overhaul is the headline. According to MacRumors a AppleInsider, the new Siri turns into something that feels like a chatbot rather than a voice command parser. You will see a glowing border on the Dynamic Island when you invoke it, and a dedicated Siri app comes preinstalled on iOS 27 and macOS 27, where you can hold back-and-forth conversations and view your conversation history just like you would in Claude or ChatGPT.

Capability-wise, the leaks point to three big upgrades. Siri will handle multi-step tasks across apps with a single command, like “find the email from my landlord, summarize it, and add the rent date to my calendar.” Personal context awareness pulls information from your messages, mail, and calendar to answer questions. And on-screen awareness lets Siri see what is on your iPhone or Mac at the moment of the request. You can ask it about a photo, an article, or a Maps result without having to describe what you are looking at.

Mark Gurman’s reporting frames the broader project as Apple’s catch-up moment. Siri has been behind ChatGPT, Claude, and Gemini for two years, and Apple needs to deliver a credible chatbot at WWDC 2026 to stop hemorrhaging mindshare to apps people install themselves. The Snow Leopard analogy applies to iOS 27 as a whole, performance and stability over a long feature list, but Siri 2.0 is the one piece getting headline treatment.

iOS 27 Extensions: Claude, Gemini, and ChatGPT in Siri

This is the single biggest piece of news for anyone who already uses third-party AI on Apple devices. Bloomberg reported on March 26, 2026 that Apple plans to introduce an Extensions system in iOS 27, iPadOS 27, and macOS 27 that lets you pick which AI assistant Siri hands off to. The current setup ties Siri to ChatGPT through OpenAI’s exclusive partnership; the new system breaks that exclusivity wide open.

In practice, you will see a list of installed AI apps in the Apple Intelligence section of Settings, similar to how default browsers and email apps work today. Install the Claude app and you can route Siri questions to Claude Opus 4.7. Install Gemini and you can route them to Google’s flagship. The same path is open to Grok, Perplexity, and any other AI maker that ships an Extensions integration. According to 9to5Mac quoting Bloomberg, Anthropic and Google are the first two named third-party partners alongside the existing ChatGPT integration, with the door open for more.

The strategic shift here is enormous. Apple is essentially saying it is fine if its on-device Apple Intelligence handles routine work and a third party handles the heavy lifting. For Mac and iPhone users, this means the choice of AI app is about to matter more than the choice of operating system.

If you are buying a new Mac in May or June with a multi-AI workflow in mind, the best ChatGPT alternatives for Mac roundup is a sensible starting point. Installing one app that already handles all five major models avoids the friction of juggling separate accounts and subscriptions.

The Multi-model AI App

This is also where Fello AI fits the picture cleanly. Rather than installing the ChatGPT, Claude, Gemini, Grok, and DeepSeek apps separately and managing five subscriptions, Fello AI gives you all of them in one Mac and iPhone app for $9.99 per month, with no API keys and no provider lock-in. It already has 25,000+ five-star reviews across the App Store. The way Apple is structuring iOS 27 Extensions makes the multi-model angle stronger, not weaker, because you keep flexibility no matter which model wins next quarter.

Other iOS 27 and macOS 27 Features Leaked Ahead of WWDC 2026

Beyond Siri, Visual Intelligence is getting the biggest expansion. iOS 27 leaks point to a dedicated Siri Camera Mode in the Camera app’s mode strip, sitting next to Photo, Video, and Portrait. Visual Intelligence will scan nutrition labels and pull phone numbers and addresses from photos directly into Contacts and Health. It will also scan physical tickets straight into Wallet and automatically name Tab Groups in Safari based on the open pages. These are small features individually but they collectively turn the iPhone camera into a working AI assistant rather than a separate app.

iOS 27 also expands satellite connectivity. According to Digit.in and other leakers, you will get Apple Maps via satellite for offline navigation, and Messages will support sending and receiving photos over satellite for the first time. Combined with the existing satellite text and emergency features, iPhones become useful in places with zero cell service, which is a meaningful upgrade for outdoor users.

The Snow Leopard

The Snow Leopard framing is the other through-line. Mark Gurman reports that Apple’s engineering teams have spent the year hunting down bloat and bugs rather than racing for new features, and the result is an OS focused on speed, battery life, and overall reliability. Apple is reportedly testing a system-wide intensity slider for the Liquid Glass design that shipped in iOS 26, letting you tune transparency and motion to taste. None of this is glamorous, but if your iPhone has felt sluggish since late 2025, this is the release that fixes it.

One footnote: iOS 27 drops support for the iPhone 11, iPhone 11 Pro, iPhone 11 Pro Max, and iPhone SE (2nd generation), per a MacRumors leak published on April 20. Those devices will keep getting iOS 26 security updates for at least a few more years, but the new Siri, Visual Intelligence, and Extensions features need newer hardware. macOS 27 stays Apple silicon only, so any Intel Mac is out.

Hardware Rumors: M5 Mac mini, iMac, and Mac Studio

WWDC has historically been a software event, but Apple does occasionally drop hardware on stage. The strongest rumors for WWDC 2026 center on the M5 chip family. The base M5 is expected in a refreshed Mac mini a iMac 24-inch, while the M5 Max and M5 Ultra are rumored for a new Mac Studio. The iPad refresh is tipped for the A18 chip, and Apple TV may finally get the A17 Pro, possibly with HDMI passthrough that lets it act as a central home entertainment hub.

The bigger hardware story actually lands in September. iOS 27’s multitasking architecture is being shaped around the long-rumored foldable iPhone, which Apple is reportedly preparing for a fall release. The Mac Studio and any new Mac mini that ships at WWDC will hit shelves before then. None of this is confirmed, so treat it as directional rather than definite, and check the best AI models comparison hub if you are weighing a new Mac purchase against AI workload requirements.

What WWDC 2026 Means for Mac and iPhone AI Users

If you already use AI heavily on your Mac or iPhone, WWDC 2026 changes two things. First, Siri stops being a closed system tied to OpenAI. Whichever model you prefer, you can route Siri queries to it through the Extensions system, and Apple is making this a first-class feature rather than a workaround. Second, the line between “AI in the OS” and “AI app I install” is dissolving. Apple Intelligence handles the on-device work, the cloud part you control through whatever provider you trust most.

For most readers this argues for keeping a multi-model app installed regardless of which AI you currently favor. Models leapfrog each other on a quarterly cadence now. GPT-5.5 launched on April 23, 2026 with a record-setting Intelligence Index score and a 60% drop in hallucinations vs GPT-5.4. Claude Opus 4.7 still leads on SWE-bench Pro coding. Gemini 3.1 Ultra dominates long-context and Google Workspace integration. DeepSeek V4 Pro undercuts everyone on price by roughly 7x.

Locking yourself into a single vendor in May 2026 is the wrong move. Fello AI is built for exactly this market. For $9.99 per month you get Claude, ChatGPT, Gemini, Grok, and DeepSeek in one native Mac and iPhone app, no API keys, 25,000+ five-star reviews. You also keep your conversation history when you switch models inside a single thread.

Závěr

WWDC 2026 is going to be remembered for two things, the moment Siri became a real chatbot and the moment Apple stopped being an OpenAI-only AI platform. June 8 at 10am PT is the keynote you want to watch live.

If you are an AI-first Mac or iPhone user, stop locking yourself into a single AI provider. By September you will be able to route Siri to any of them. Get Fello AI on the App Store if you want one app that already handles Claude, ChatGPT, Gemini, Grok, and DeepSeek for $9.99 per month.
