iOS 27 Public Beta Brings Siri AI: What’s Actually New

Apple has released iOS 27 as a public beta, and it includes the first broadly available version of its revamped assistant, now called Siri AI. First shown at WWDC in June, Siri AI adds a chatbot-style app, deep integration across the iPhone's operating system, and on-device indexing that lets Siri pull context from your messages, calendar, and apps. The overhaul is real but incomplete: the app still lacks a memory feature, meaning Siri forgets your preferences between sessions.

What happened

Detail	Fact
Software version	iOS 27 public beta
Feature name	Siri AI
First announced	WWDC, June
Indexing time (WIRED test device)	Just over one week
Test device	iPhone 16 Pro Max
Conversation retention options	Forever, 1 year, or 30 days

Apple has opened iOS 27 to the general public as a beta, bringing the rebranded Siri AI out of developer-only access for the first time. You can enroll through Apple’s Beta Software Program, but after installing the update you still need to join a Siri AI wait list inside Settings. Apple sends a notification once you have access.

WIRED’s hands-on with earlier developer betas found the assistant genuinely useful for tasks like surfacing old photos, composing texts, and finding nearby restaurants. Their test on an iPhone 16 Pro Max went without any serious software problems.

What’s new inside Siri AI

A chatbot-style app

Siri now has a dedicated app. It functions mainly as a conversation log: you can scroll back through past sessions or pick up an old thread. You can also start a new chat from the app, though Siri is also embedded directly into the phone’s search function. Swiping down from the home screen surfaces a “Search or Ask” bar where typing a query sends it straight to Siri.

Conversation history can be controlled under Settings > Siri AI > Keep Conversations. Options are forever, one year, or 30 days. Switching to a shorter window deletes older chats immediately.

On-device personal context

The most meaningful change is how Siri reads your device. During setup, the iPhone builds a local, searchable database of your data. Apple labels the process “Optimizing Search and Siri” in recent betas, with a progress bar to show completion. On WIRED’s test device it took just over a week.

Once indexed, Siri can scan texts, calendar events, and app activity to answer questions. In one test, asking Siri what was coming up that week prompted it to surface a TikTok Shop delivery from a text thread and flag a movie that friends had mentioned in a group chat, plus a birthday party and a live performance from the calendar.

According to Josh Clark, principal at digital-design agency Big Medium and co-author of Sentient Design: Crafting Intelligent Interfaces with AI, this is a structural advantage over external chatbots: “Siri AI has access to the kind of context that things like ChatGPT and Claude can’t easily have, because Siri is cooked into the operating system.”

If you want to block Siri from learning from a specific app, go to Settings > Siri AI > App Access, pick the app, and toggle “Learn from this App” off. These toggles are all on by default when Siri AI is enabled.

What’s still missing

The chatbot app does not yet have a memory feature. Competitors like ChatGPT and Claude store user preferences so you don’t have to repeat yourself. Siri AI does not, so it won’t remember that you’re vegan the next time you ask for recipe help. Apple has not announced a timeline for adding memory, though it is expected to keep iterating on the product.

Nabila Popal, senior research director at International Data Corporation, told WIRED the integration work is solid: “They’ve integrated it across the entire ecosystem, so you can access Siri AI no matter where you are on the device.” But that integration is only as useful as the underlying AI, and memory gaps are a real friction point for daily use.

Why it matters

Apple is the world’s largest consumer device platform. A deeply embedded AI assistant that reads your messages, calendar, and apps is a meaningful shift in how people might use an iPhone every day. It also raises the bar for what users expect from voice and chat interfaces on any device.

For businesses, the more relevant question is behavioural: if more iPhone users start using a well-integrated AI assistant to find local services, draft messages, and navigate apps, that changes how people interact with search and web content. An assistant that pulls driving directions straight from a query, for example, may reduce the number of taps that ever reach a browser or a Google results page. Teams thinking about SEO and organic visibility should watch whether on-device AI starts eating into mobile search traffic.

Our take

The practical gap here is memory, and it’s not a small one. Any AI assistant that forgets your preferences between sessions adds friction rather than removing it. Apple is playing catch-up to ChatGPT and Claude on this specific feature, and until that changes Siri AI will feel incomplete for people who use AI tools daily.

That said, the on-device context angle is real. A model that can see your actual messages and calendar without you uploading anything is genuinely more useful for personal scheduling and local task management than a cloud chatbot working from whatever you paste in. We’ve seen similar logic play out in AI integration work for clients: the closer the AI sits to the data, the less effort the user has to spend bridging the gap.

Wait for the stable release before recommending this to clients or less technical users. Public betas are betas. The indexing week is real downtime for a feature that is meant to be always-on.

What to do about it

1. Back up your iPhone before installing any beta software.
2. Enroll at Apple’s Beta Software Program, then install iOS 27.
3. Go to Settings, find Siri AI, and join the wait list.
4. Let the on-device indexing run to completion before testing Siri’s personal context features.
5. Review Settings > Siri AI > App Access and turn off data sharing for any apps you want kept private.
6. Set your conversation retention window (forever, one year, or 30 days) under Keep Conversations.

If you ship mobile-first products, this is worth testing now so you understand how your users may start interacting with their phones differently by the time iOS 27 hits stable release.
