Apple Intelligence is the suite of on-device AI features Apple introduced with iOS 18, iPadOS 18, and macOS Sequoia. Summarizing text, rewriting drafts, generating images, a noticeably smarter Siri — work that used to require third-party AI apps can now happen right on your device.
The catch is that supported models are limited and language support has rolled out in stages, so it's easy to lose track of who can actually use what. This guide walks through which devices are supported, how to enable Apple Intelligence, and the major features you can use today.

What Apple Intelligence Is
Start by understanding where Apple Intelligence sits in the stack.
The Core Concept
Apple Intelligence is a set of AI capabilities Apple announced in 2024 that run primarily on the device itself. Text understanding, image generation, summarization, and search all execute locally, and only fall back to Apple's own servers (Private Cloud Compute) when extra compute is needed. Unlike ChatGPT or Google Gemini, there's no separate account to sign up for and no monthly fee — it's bundled with the operating system.
How It Differs From Older Siri and External AI
Old Siri was essentially a voice command interpreter. Apple Intelligence is more context-aware: it can summarize the body of an email, identify people in a photo, and respond to questions that depend on what's currently on screen. When a request needs heavier reasoning, you can hand off to ChatGPT directly from the same interface.
Supported Devices and Language Coverage
Apple Intelligence does not run on every iPhone, iPad, or Mac.
Compatible iPhones
The supported iPhones are the iPhone 15 Pro and 15 Pro Max plus every iPhone 16 model. The standard iPhone 15 / 15 Plus and anything older than the iPhone 14 series don't have the A17 Pro chip and are not supported. This has been a real factor in used-phone pricing and an argument for upgrading sooner than usual.
Compatible iPads and Macs
For iPad, you need an M-series chip (M1 or later) — applicable iPad Pro, iPad Air, and iPad mini models. For Mac, any Apple Silicon Mac (M1 or later) is supported: MacBook Air, MacBook Pro, Mac mini, iMac, Mac Studio, and Mac Pro. Intel Macs are excluded.
Language Support
Japanese support rolled out in iOS 18.4 in spring 2025, and other languages have been arriving on a similar staggered schedule. The major features — Writing Tools, summaries, Image Playground — all work in supported languages, but a few smaller features remain English-only for now.
How to Enable Apple Intelligence
Even on a supported device, Apple Intelligence is off by default.
Requirements and Prep
You need iOS 18.1 or later on iPhone, iPadOS 18.1 or later on iPad, and macOS Sequoia 15.1 or later on Mac. Update via Settings → General → Software Update. Your device language and Siri language must also be set to a supported language pair.
Turning It On in Settings
Open Settings → Apple Intelligence & Siri and tap Turn on Apple Intelligence. The first time you enable it, the device downloads the model files, so you'll want to be on Wi-Fi with a few GB of free storage. On Mac, the equivalent path is System Settings → Apple Intelligence & Siri.
The First-Time Download Wait
The initial download can take anywhere from a few minutes to several hours, and you may sit in a queue before it even starts. There's no rush in most cases — turning it on overnight while the device is charging is the painless option.
What Apple Intelligence Can Do
Here are the main capabilities you'll actually use.
Writing Tools
Select any text in Mail, Notes, or a supporting third-party app and Writing Tools appears: proofreading, summarization, tone changes (professional, friendly, etc.), and bullet-point conversion. It's basically "ask ChatGPT to clean this up," but built into the OS keyboard layer.
Mail and Notification Summaries
The Mail app puts an AI-generated summary at the top of long messages, and the preview line in the inbox shows a summary instead of the first few words. Notifications get a "Priority Notifications" treatment that pushes the genuinely important ones to the top.
Image Playground and Genmoji
The Image Playground app generates images from text prompts in three styles — animation, illustration, and sketch. Genmoji lets you spin up custom emoji on the fly and use them in Messages and other apps.
The New Siri
Siri got a new look (the screen edges glow) along with more natural conversation, the option to type instead of speak, and an awareness of what's on screen. "Make a reservation at the place on screen" — that kind of context-bound request actually works now. Enable ChatGPT integration and harder questions can be handed off seamlessly.
Call Recording and Transcription
iOS 18 introduced built-in call recording and transcription. On Apple Intelligence-supported devices, the system also generates an AI summary of the recorded conversation. For step-by-step instructions and the legal caveats, see How to Record Phone Calls on iPhone.
Things to Watch Out For
There are real benefits, but also a few things worth knowing.
Privacy and Private Cloud Compute
Most processing stays on device. When something needs more compute, the request goes to Private Cloud Compute (PCC), an Apple-designed server environment whose architecture is publicly documented. Apple commits to not storing the request data and not retaining operational logs. The ChatGPT handoff is the only case where a separate consent prompt appears, because that data leaves Apple's stack.
Battery Impact
AI workloads are compute-heavy, so you may notice a small uptick in battery drain right after enabling Apple Intelligence. Turning off features you don't use (in Settings → Apple Intelligence & Siri) and combining with Low Power Mode mostly closes the gap.
When Features Don't Appear
Even when all the requirements are met, the features sometimes just don't show up. The usual fix sequence: toggle Apple Intelligence off and back on, restart the device, then re-check Software Update. One of those three almost always resolves it.
Wrap-Up
For supported devices, Apple Intelligence is a no-extra-cost AI layer that lifts writing, mail processing, image generation, and Siri all at once. If you own a compatible device and haven't enabled it, you're leaving real value on the table — at minimum, Writing Tools and notification summaries are worth turning on today.
In my own use, the mail summaries and Writing Tools' proofreading have noticeably cut the time I spend on routine writing. The trick is to weave the features into your daily workflow gradually rather than trying to use everything at once.
