Apple Intelligence vs Samsung Galaxy AI in 2026: The Honest Comparison

Updated June 2026

Apple announced at WWDC 2026 that the rebuilt Siri runs on Apple Intelligence and is powered in part by Google's Gemini models, the same family behind much of Samsung's Galaxy AI. The new Siri needs an iPhone 16 or later, or iPhone 15 Pro; Galaxy AI runs on the Galaxy S25.

At WWDC 2026 on June 8, Apple did something it rarely does: it rebuilt Siri from the ground up on Apple Intelligence and, per Apple, powered it in part by Google's Gemini models. That is notable because Gemini is also a backbone of much of Samsung's Galaxy AI. So the real question is no longer "whose AI is smarter" in the abstract, it's which assistant fits the phone, the apps, and the people already in your life. This guide compares the new Siri against Galaxy AI as honestly as we can, flags what Apple has and hasn't shipped, and tells you who should pick which phone. We'll only claim Apple features Apple actually announced, and we'll be precise about the catch that trips up most buyers: which phones can even run the new Siri.

They now share a brain, so what's the real difference?

The headline from WWDC 2026 is that Siri was rebuilt on Apple Intelligence and, Apple says, runs in part on Google's Gemini models. Galaxy AI on phones like the Galaxy S25 has leaned on Gemini for a while. So both assistants draw from a similar class of model, which means the gap is less about raw conversational ability and more about integration. The thing that separates them is how deeply each one reaches into the phone you already use. Apple announced that the new Siri understands personal context and on-screen awareness, so it can take action based on what's on your screen, hold a back-and-forth conversation, and do tasks like adding photos to an album, setting reminders, suggesting recipes, or giving feedback on a document. Galaxy AI's strength has long been the same idea expressed in Android's open, customizable way. If you're weighing a current flagship from each camp, the iPhone 17 and the Galaxy S25 are the natural head-to-head.

Pros

  • Both assistants now build on a similar class of Gemini-based models
  • Apple's new Siri adds on-screen awareness and personal context
  • Galaxy AI brings Android's openness and deeper default-app control

Cons

  • The new Siri is English only at launch and delayed in the EU on iPhone and iPad
  • Cross-brand feature names differ, so a direct spec-for-spec match isn't possible

The catch nobody mentions: which phones can run it

This is where the buying decision actually gets made. Apple announced that iOS 27 itself installs on a wide range of iPhones, the same lineup as iOS 26, going back to the iPhone 11 and second-generation iPhone SE. But the marquee AI, the new Siri and Apple Intelligence, needs an iPhone 16 or later, or an iPhone 15 Pro or 15 Pro Max. It does not run on the iPhone 15 (non-Pro), the iPhone SE, the iPhone 14, or the iPhone 11. So an older supported iPhone updates to iOS 27 and gets the refreshed look and speed improvements, but not the conversational Siri. If the new AI is the reason you're upgrading, you need an iPhone 16 or later, or the 15 Pro. On the Android side, Galaxy AI ships on the Galaxy S25 today, so there's no separate hardware gate to clear.

Beyond Siri: the rest of Apple Intelligence

Apple Intelligence in 2026 is more than the assistant. Apple announced Safari tools that organize tabs by topic, notify you when a webpage changes, and generate custom extensions. Passwords gets one-tap credential strengthening that can agentically update the password on the website for you. Messages and Mail offer smart replies that mimic your writing style, and Calendar can create or modify events from a plain-language description. Image Playground generates photorealistic images and wallpapers, while Photos adds virtual reframing and image-expansion editing, with AI-generated content carrying SynthID watermarks. There's also a dedicated Siri app on iPhone, iPad, and Mac for text and image generation and file analysis, a chatbot-style experience. Galaxy AI covers similar ground in writing help, photo editing, and search on the Galaxy S25, expressed through Android. Whichever ecosystem you choose, these are the kinds of features that make a flagship like the iPhone 17 feel current.

Where Apple Intelligence reaches across your devices

One genuine Apple advantage is breadth across hardware. Apple announced that the new Siri is available across iOS, iPadOS, macOS Golden Gate, watchOS, visionOS, CarPlay, and AirPods, so the same assistant follows you from phone to laptop to wrist to car. Apple Intelligence runs on iPads with M-series or A17 Pro chips, Macs with M1 or later, Apple Vision Pro, and Apple Watch Series 10 and later when paired with a supported iPhone. If you already live in that world, an iPad or a recent MacBook extends the same AI rather than bolting on a second system. Galaxy AI is strongest when paired within Samsung's and Google's own ecosystem. This is less about which assistant is cleverer and more about how many of your screens it touches; if you own several Apple devices, that continuity is a real, practical reason to stay.

So which should you actually buy?

Be honest about your ecosystem before you read another spec. If your messages, earbuds, and laptop are already Apple, and you want the new Siri's on-screen awareness woven through all of them, get an iPhone that supports it, the iPhone 17 is the sensible default for most people, and step up only if cameras or battery push you to the Pro. If you prefer Android's openness, want to set your own default apps, or already use Google services heavily, the Galaxy S25 gives you Galaxy AI without compromise. And if you specifically want the new Siri, double-check the hardware: an iPhone 15 or older won't run it, even after updating to iOS 27. The assistants are closer than the marketing suggests, so the deciding factor is which phone fits your life with the least friction.

The verdict

There's no single winner, because the two assistants now share a similar Gemini-based foundation. The new Siri's edge is reach across Apple's devices and on-screen context; Galaxy AI's edge is Android's openness on the Galaxy S25. Pick by ecosystem. If you want the new Siri, just confirm your iPhone supports it: an iPhone 16 or later, or a 15 Pro.

Who should skip this

Skip the upgrade entirely if you own an iPhone 16 or 15 Pro that already runs the new Siri, since you've got it. If you're holding an iPhone 15, SE, or 11 mainly for the AI, know that iOS 27 will not bring the new Siri to those phones, so you'd need a newer iPhone or a Galaxy S25. And if you don't care about an AI assistant at all, don't pay a premium for it; buy the phone that fits your budget and ecosystem.

How we chose

We based every Apple claim on what Apple announced at WWDC 2026, including the rebuilt, Gemini-powered Siri and its device requirements, rather than on speculation or benchmarks. We compared the two AI systems on the things that change daily use, ecosystem fit, device support, and feature breadth, instead of chasing a spec-for-spec scoreboard, since the assistants now share a similar model foundation. Recommendations favor the phone that causes the least friction for a given person.

Frequently asked

Is the new Siri really powered by Google's Gemini?

In part, yes. Apple announced at WWDC 2026 that the rebuilt Siri runs on Apple Intelligence and is powered in part by Google's Gemini models. Gemini is also a backbone of much of Samsung's Galaxy AI, so the two assistants now share a similar class of underlying model.

Which iPhones can run the new Apple Intelligence Siri?

Apple announced that the new Siri needs an iPhone 16 or later, or the iPhone 15 Pro and 15 Pro Max. It does not run on the iPhone 15 (non-Pro), iPhone SE, iPhone 14, or iPhone 11. Those older models can still update to iOS 27, they just won't get the new Siri.

Will my iPhone 15 or iPhone 11 get the new Siri after updating to iOS 27?

No. Apple announced that iOS 27 installs on iPhone 11 and later, so those phones get the redesign and speed improvements. But the new Siri and Apple Intelligence require an iPhone 16 or later, or a 15 Pro, so a standard iPhone 15, SE, or 11 won't run it.

Is Apple Intelligence available everywhere at launch?

Not yet. Apple announced that the new Siri is English only initially, and it's delayed in the EU on iPhone and iPad due to the Digital Markets Act. Developer betas arrived June 8, 2026, with a public beta in July and the full free release this fall.

iPhone or Galaxy for AI in 2026?

Decide by ecosystem, not by the AI alone. The assistants are closer than the marketing implies. Choose an iPhone that supports the new Siri, such as the iPhone 17, if you're already in Apple's world; choose the Galaxy S25 if you prefer Android's openness and Google services.

Does the new Siri work on Apple Watch and CarPlay too?

Yes. Apple announced that the new Siri is available across iOS, iPadOS, macOS Golden Gate, watchOS, visionOS, CarPlay, and AirPods. On Apple Watch it needs Series 10 or later paired with a supported iPhone, so the same assistant can follow you across your Apple devices.
