Our Top Pick: Upgrade to a Siri AI‑Ready iPhone First
Apple’s new Siri AI is a conversational assistant built into a dedicated app across iPhone, iPad and Mac that lets you type or speak queries, saves them as ongoing conversations, and keeps everything synced via iCloud for easy reference later across all your devices. For most people, the smartest move is clear: make your next phone an iPhone 17 or iPhone 17 Pro, because iPhones are getting Siri AI first and will deliver the most complete experience day one. These models sit at the center of Apple’s ecosystem and are the devices you reach for constantly, so they should be the ones that support the new assistant from the start. While Siri AI will also reach recent iPads, Macs, Apple Watch and Vision Pro, the phone is where new AI features feel instant and useful, from quick questions to managing daily tasks.
Siri AI Features and How the New App Works
Siri AI arrives as a separate app in iOS 27, iPadOS 27 and macOS 27 Golden Gate, working much like other text‑based AI chat tools but tightly integrated with Apple’s voice assistant and cloud sync. You can type or use your voice to ask questions, and every query is stored as part of a conversation you can reopen later, whether you started it with the app or with the traditional Siri button or wake phrase. All of these chats sync over iCloud, so a question you ask on your iPhone is visible on your iPad and Mac without any setup. You can change the conversation view style between list and grid to fit how you browse your history, rename threads to keep topics organized, and pin important conversations at the top so reference material stays where you need it. Together, these make Siri AI feel more like a personal knowledge log than a fleeting voice command.
Device Compatibility: Who Gets Siri AI First
Siri AI will roll out with iOS 27, iPadOS 27, macOS Golden Gate and watchOS 27, but not every device that can install these updates will support the new assistant. The first wave of compatible hardware is focused on recent and higher‑end models. On iPhone, that includes iPhone 15 Pro and Pro Max, all iPhone 16 variants, iPhone 17, iPhone 17e, iPhone 17 Pro and Pro Max, plus iPhone Air. On iPad, you need iPad Pro or iPad Air with at least an M1 chip, or the latest iPad mini with an A17 Pro chip. All Macs with Apple silicon starting from M1, and those with the A18 Pro chip, are included, as are all Vision Pro models and Apple Watch Series 9, Apple Watch Ultra 2 and Apple Watch SE 3. The watch must be paired to an Apple Intelligence‑supported iPhone to use Siri AI features, reinforcing that the phone remains the hub.
Advanced Siri AI Features Need Newer Chips
Not all Siri AI features arrive everywhere at once, and some of the most expressive options are reserved for the newest hardware. Basic conversational features, saved chats and iCloud sync will reach all listed compatible devices. However, Apple has limited more advanced controls, such as changing Siri AI’s pace and expressivity, to a subset of products with stronger processors and more memory. According to one report, these options require iPhone 17 Pro, iPhone 17 Pro Max, iPhone Air, iPads with an M4 chip or later and at least 12GB of unified memory, Macs with M3 or later and at least 12GB of unified memory, and Apple Vision Pro with an M5 chip. That means even if your current device supports Apple Intelligence and the new Siri app, you may miss some fine‑tuning tools unless you step up to this newest tier.
Customizing Siri AI Across iPhone, iPad and Mac
Once you have a compatible device, you can personalize Siri AI so it behaves the way you prefer on each screen. Inside Settings on iOS 27 or System Settings on macOS 27 Golden Gate, you can choose whether the Siri app opens straight into a fresh conversation or shows your recent threads first. You can also adjust how many lines of each answer appear in the conversation list, from none up to five lines, if you want a denser or more minimal overview. For privacy and tidiness, there is a Keep Conversations option that lets you automatically delete chats after 30 days or one year instead of keeping everything forever. In the app itself, you can quickly select and delete multiple conversations using familiar multi‑selection gestures, and on iPad you can even open a chat in a separate window for side‑by‑side work. These controls make Siri AI feel tailored rather than generic.
Buy if / Skip if
- Buy the iPhone 17 Pro if you want the fullest Siri AI experience, including advanced pace and expressivity controls on day one.
- Skip the iPhone 15 Pro if you specifically need the newest expressive Siri AI voice controls, which are reserved for later chips.
- Buy the iPad Pro (M1 or later) if you plan to use Siri AI as a long‑form research and note‑taking tool with synced conversations.
- Skip the Apple Watch Series 9 if you do not own an Apple Intelligence‑supported iPhone, since Siri AI on watch depends on that pairing.
- Buy the Mac with Apple silicon (M1 or later) if you want desktop access to the Siri app with shared conversations and customization options.
- Skip the iPad mini without A17 Pro if your main goal is trying Siri AI, because older mini models are not on the supported list.
