The short version: At WWDC on 9 June, Apple announced that Siri is being rebuilt on Google's Gemini model for iOS 27. Users can also choose Claude as their AI instead. For tradespeople and service business owners who use iPhone for customer calls, estimates, and scheduling, this is the most significant practical AI upgrade to arrive on your existing device — and it costs nothing extra.
What Apple announced at WWDC 2026
Tim Cook's keynote on 9 June was headlined by one change above all others: Siri has been rebuilt. The version of Siri shipping with iOS 27 this autumn is powered by Google's Gemini model and can handle complex, multi-step tasks across the entire iPhone ecosystem — not just simple one-question commands.
Alongside the Gemini-powered default, Apple introduced "AI Extensions" — a framework that lets users set a different AI model as their primary assistant. Claude is available from day one as an alternative. This is a first for Apple: the company has previously kept its AI stack entirely proprietary. Offering Claude as a first-class option signals how seriously Anthropic's lead in practical AI capability is being taken across the industry.
The broader iOS 27 rollout also includes upgraded AI tools for photos, messaging, and document handling, plus a rebuilt on-device intelligence layer for privacy-sensitive tasks. The focus is on AI that works even when connectivity is limited — relevant for tradespeople working on-site or in rural areas.
What a Gemini-powered Siri actually does differently
The existing Siri is limited to simple commands — set a timer, call a contact, open an app. The new version understands context and can execute across applications. Practical examples that Apple demonstrated include: booking an appointment by parsing an email and adding it to Calendar; drafting a reply in the customer's tone based on a voice prompt; pulling invoice totals from a document and updating a Numbers spreadsheet; and handling multi-part instructions like "find my last quote for [customer name], update the price by 10%, and send it to them."
For a service business owner managing customer communications, pricing, and scheduling from a single iPhone, these are tasks that currently require switching between multiple apps and manual copy-paste. The rebuilt Siri handles them in a continuous voice conversation.
Why the Claude option matters
For businesses that have already integrated Claude-based workflows — document processing, customer communication drafts, quote generation — the option to use Claude as the primary iPhone AI creates continuity. The same model handling your business logic on a laptop or desktop can now handle voice interactions on the device you carry everywhere.
The AI Extensions framework also suggests Apple is comfortable competing on its hardware and privacy architecture rather than its AI model. That is a structural commitment: third-party AI providers including Anthropic and Google are first-class participants in the iPhone platform going forward, not workarounds.
The practical timeline for UK operators
iOS 27 arrives this autumn — typically a September release in the UK. If you are on an iPhone 15 or newer, you will receive it as a standard software update. No new hardware is required for the core AI features, though some on-device intelligence capabilities require the most recent chip generations.
The practical move between now and September is not to wait passively but to start using voice commands for business tasks today — even with the current Siri. The habit of talking to your phone to get work done is more valuable than any specific model. When iOS 27 arrives with meaningfully better AI, you will be positioned to use it immediately rather than discovering it months after your competitors.
Operator move for this week
Spend five minutes today testing voice commands for your three most common iPhone tasks — drafting a customer reply, checking your schedule, or finding a contact's last communication. Note where the current Siri falls short. Those are precisely the gaps the rebuilt version addresses. You will have a working shortlist ready the day iOS 27 ships.
