Siri AI Review (2026): Apple's Rebuilt Assistant vs ChatGPT & Gemini [Tested]

Short answer: Siri AI is Apple’s ground-up rebuild of Siri, announced at WWDC 2026 on June 8. It’s powered by Apple Intelligence and Google Gemini models. For the first time, Siri gets a dedicated app, conversation history, personal context across your apps, on-screen awareness, and system-wide writing tools. Developer beta is live now. Public beta arrives later this year in English first.

Verdict: Watch for most users until the public beta proves the demos hold up. Use if you live inside the Apple ecosystem and want an assistant that actually knows your stuff without sending it to a third-party cloud. Skip if you need advanced coding help or live in a region where it isn’t launching yet.

Quick specs

What happened: the two-year delay

Apple first promised a smarter Siri at WWDC 2024. It didn’t ship. The company delayed it twice, then announced Siri AI at WWDC 2026 on June 8, two years behind schedule. Here is why that context matters for anyone deciding whether to trust this launch.

You need the backstory to understand why Siri AI matters.

At WWDC 2024, Apple showed a smarter Siri with on-screen awareness and personal context. It was supposed to ship with iOS 18. It didn’t. Apple delayed it twice. In March 2025, the company said Siri was delayed indefinitely. By October 2025, Tim Cook promised it would arrive “on time” in 2026.

In the meantime, ChatGPT added voice, vision, and agent mode. Gemini on Android started chaining tasks across Google apps. Claude became the go-to for writing and coding. Siri stayed the same.

WWDC 2026 was the do-over. Apple tore Siri down and rebuilt it on a new architecture, partnering with Google Gemini to do it.

The new architecture: what changed under the hood

Siri AI runs on a three-layer system: on-device processing for personal queries, Apple’s Private Cloud Compute for heavier tasks, and Google Gemini models at the foundation layer. Your data stays on your device or in Apple’s private cloud. It doesn’t go to Google.

Apple made three big architectural shifts that separate Siri AI from old Siri.

First, on-device processing as the default. Siri AI runs a second-generation on-device model for most tasks. It indexes your messages, emails, photos, calendar, and notes locally using Spotlight’s semantic index. When you ask something personal, the answer comes from your device, not a server.

Second, Private Cloud Compute for tougher queries. When a prompt is too complex for the on-device model, it goes to Apple’s servers running Private Cloud Compute. Apple says personal data isn’t stored and isn’t accessible to Apple or anyone else during these sessions. Outside experts can verify this claim.

Third, Google Gemini at the model layer. This is the twist. Apple confirmed a collaboration with Google. Gemini technologies power the next generation of Apple Foundation Models. We track every major foundation model release in our latest AI models hub — the Apple/Gemini partnership is a new entry worth watching. But Gemini sits at the infrastructure level. Your personal data doesn’t go to Google. It flows through Apple’s own architecture and privacy rules.

Compare this to how Gemini works on Android: you opt into sharing your Gmail or calendar, and then Gemini reaches into those sources directly. Apple’s approach is different. The data stays indexed on your device or in Private Cloud Compute. The model is smarter, but the privacy model is the same one Apple has been selling for years.

Key features

Siri AI adds six major capabilities that old Siri never had. Personal context lets it search your messages, emails, and photos. On-screen awareness reads what’s on your display. A dedicated app stores conversation history. Cross-app actions chain tasks together. Visual Intelligence analyzes what your camera sees. Write with Siri drafts and edits text anywhere you type.

Personal context understanding

This is the feature Apple promised in 2024 and finally delivered. Siri AI can search across your messages, emails, photos, calendar, and notes to answer questions about your life.

In the WWDC keynote, a presenter asked Siri about a dessert from an event. Siri found it in Messages, compiled a watch party menu, and drafted a message to contacts. The Verge tested this hands-on: Allison Johnson asked Siri when she needed to return rented gear. It found the answer from a calendar event and an email.

On-screen awareness

Siri AI can read what’s on your screen and respond based on it. In the keynote, a presenter asked about a location in an Instagram post and Siri identified it. The Verge confirmed this works consistently: prompting Siri with “add these events to my calendar” triggered it to reference the information visible on screen. Apple says it works system-wide.

Dedicated Siri app

For the first time, Siri has its own app. It looks like ChatGPT or Claude: a conversation interface with text and voice input, saved history, and cross-device sync through iCloud. Start a chat on your Mac, continue it on your iPhone. The old Siri disappeared after each query. The new one remembers.

Cross-app actions

Siri AI can chain actions across multiple apps. The keynote showed it adding calendar events from a poster by pointing the camera at it, splitting a bill from a receipt, and composing emails pulling context from messages and calendar. The system orchestrator works on device through the App Intents framework.

Visual Intelligence

Siri AI gets a visual understanding layer across platforms. On iPhone, it’s built into the Camera app as a dedicated Siri mode. Point the camera at a poster and Siri adds events to your calendar. Point it at a receipt and it splits the bill. On Vision Pro, users can look at a floating Siri orb and start a conversation without saying “Hey Siri.”

Write with Siri

System-wide writing tools let you generate and edit text anywhere you type. You describe what you want, Siri drafts it. You describe a change, Siri updates it. In Mail and Messages, Siri learns how you communicate with each contact. Send your manager bullet points? That’s what Siri produces. Casual with a friend? It matches that tone.

Voice customization

Siri AI has a new voice engine with adjustable pace, expressivity, and accent. Dictation also got a boost with automatic capitalization, punctuation, and formatting as you speak.

Platform-specific experiences

Siri AI is tailored for each device:

• iPhone: Swipe down from the Dynamic Island, press the side button, or say “Hey Siri.” The old glowing border is gone. Siri now animates from the Dynamic Island.
• iPad: Same core experience with a larger canvas for Visual Intelligence.
• Mac: Siri is integrated into Spotlight and available via right-click context menus.
• Apple Watch: Questions and actions from the wrist, plus Smart Stack suggestions.
• Vision Pro: A 3D orb users can look at to start a conversation without speaking.

What early hands-on testing shows

Early testers at WWDC got about an hour with Siri AI on developer beta devices. The consensus: it works for basic personal tasks, but it’s not pushing any boundaries. It feels like catching up to where Gemini was a year ago.

The Verge’s Allison Johnson got hands-on time at WWDC. Her summary: “It’s basic, but ‘it works’ is a big deal.”

She tested several real-world tasks. Siri diagnosed wilting roses, built a shopping list, set reminders, and added events from emails to her calendar. It referenced her email and calendar to answer “When should I leave for the airport?”

Johnson noted two things. First, Siri AI feels like “Gemini, circa 2025,” which makes sense since it runs on Gemini models. Second, Siri is more direct and less conversational than Gemini. Given the same prompt about wilting flowers, Gemini started with “That is incredibly frustrating…” while Siri got straight to diagnosis.

TechRadar’s Lance Ulanoff tested Siri AI across iPhone, Mac, and iPad. He called it “long-overdue” but said it “will win you over” because of the cross-device consistency and privacy model.

The consensus from early hands-on coverage: Siri AI does what Apple says it does, which was not true of the 2024 demo. But it is not pushing any boundaries. It is catching up to where competitors were a year ago.

Privacy: Apple’s differentiator

Apple’s main pitch for Siri AI isn’t intelligence. It’s privacy. The assistant indexes your personal data on-device and only sends the minimum needed to Apple’s servers when a query is too complex. Apple doesn’t store, log, or access that data. Independent researchers can verify the claims.

Here is how it works. Siri keeps a local semantic index of your data on-device. When you ask something personal, the on-device model handles it. When a prompt needs more compute, it goes to Private Cloud Compute with only the specific data needed. This is different from ChatGPT and Claude, where everything goes to the cloud by default.

The tradeoff: on-device processing limits what Siri AI can do compared to cloud-only models. Apple is betting users will accept a more basic assistant that keeps their data private.

Device requirements and access limits

Siri AI works on any device that supports Apple Intelligence today. But the most advanced on-device features need newer hardware with at least 12GB of unified memory. Some features will have daily usage limits, with higher limits for iCloud+ subscribers.

Siri AI works on iPhone 16 and later, iPhone 15 Pro and Pro Max, iPad mini (A17 Pro), iPads with M1 or later, Macs with M1 or later, Apple Vision Pro, Apple Watch Series 9 or later, and Apple Watch Ultra 2 or later.

The advanced on-device model requires iPhone Air or iPhone 17 Pro, iPads with M4 and 12GB RAM, or Macs with M3 and 12GB RAM.

Apple says some Siri AI and Apple Intelligence features will have daily usage limits. iCloud+ subscribers get increased limits. The company didn’t specify exact numbers in the keynote.

Siri AI launches in English first. Apple says it will “quickly expand” to more languages. The EU and China are blocked at launch due to regulatory issues. India, Australia, Canada, and other English-speaking markets are expected to be included in the initial rollout, though Apple hasn’t confirmed a country-by-country list.

Siri AI vs ChatGPT vs Gemini vs Claude

Siri AI’s advantage isn’t raw intelligence. It’s integration and privacy. ChatGPT, Gemini, and Claude are all smarter at most tasks. But none of them can search your messages, photos, and calendar without you handing over access. Here’s how they stack up.

Siri AI’s advantage is not capability. It’s integration and privacy. ChatGPT, Gemini, and Claude are smarter at most tasks. But none of them can search your messages, photos, and calendar without you handing over access. Siri AI can, and Apple says it does it without storing your data.

What we cannot verify yet

We’re writing this on June 10, 2026, two days after the WWDC announcement. The developer beta is live, but the public beta is months away. Here’s what we can’t confirm until real users get their hands on it. The developer beta is live, but the public beta is months away. Here is what we do not know yet:

• Whether conversational quality holds up outside controlled demos
• How often on-screen awareness misfires
• Whether cross-app actions work with third-party apps, not just Apple’s
• What the actual daily usage limits are
• How Siri handles contradictory personal data across apps

We also cannot test the EU and China blocks. Apple’s regulatory issues in those regions could take months or years to resolve.

Who should use, watch, or skip Siri AI

The bottom line

Siri AI is the assistant Apple should have shipped two years ago. It’s not the smartest AI in the room. ChatGPT, Claude, and Gemini are all ahead on raw capability. But Siri AI does something those tools can’t: it lives inside your device, knows your stuff, and doesn’t send your data to anyone else’s servers by default.

The question is whether “private but basic” beats “smarter but in the cloud.” For users who never trusted Siri with anything beyond timers, the new app and conversation history make it feel like a real tool for the first time. For users deep into ChatGPT or Gemini, Siri AI will feel like catching up.

Apple’s execution will decide the rest. If the public beta ships on time and features work as shown, Siri becomes relevant again. If delays repeat the 2024 to 2025 pattern, the trust damage might be permanent.

We will update this review when the public beta arrives and we can test Siri AI on our own devices.
