How to Set Up Apple Intelligence on iPhone: Requirements and Steps

If you've just picked up a new iPhone, learning how to set up Apple Intelligence on iPhone takes only a couple of minutes — but compatibility, software version, storage and language are what trip people up more than the setup itself. This guide covers exactly what your iPhone needs, the steps to turn Apple Intelligence on, and what to check if the option isn't showing up.

Whether you've just unboxed a new iPhone or you're setting it up on an existing one, here's everything you need to get Apple Intelligence running properly.

Apple Intelligence is switched on from a single toggle inside Settings.

1. Apple Intelligence Requirements Before You Start

Apple Intelligence has a hardware floor rather than a simple software switch — your iPhone needs a chip powerful enough to run its on-device AI models, which is why it isn't available on every iPhone still in use today.

Bottom line: check the individual product page before ordering if Apple Intelligence compatibility is important to you, since requirements are tied to the specific iPhone model and software version.

2. How to Turn On Apple Intelligence on iPhone

Once you've confirmed your iPhone qualifies, switching it on takes just a few steps.

1. Open Settings.
2. Tap Apple Intelligence & Siri.
3. Follow the on-screen instructions to turn Apple Intelligence on.
4. Keep your iPhone connected to Wi-Fi while the required models download.
5. Wait for setup to complete.
6. Test a verified feature such as Writing Tools, if available on your device.

Menu labels can differ slightly by iOS version and region.

Bottom line: there's no separate app to install — it's built into Settings using your existing Apple Account.

3. Language and Region Requirements

Your device language and Siri language must be set to the same supported language. If either is set to an unsupported language, or the two don't match, Apple Intelligence won't be available even on a fully compatible iPhone.

Apple's current supported language list (as of iOS 26.1) includes English, Danish, Dutch, French, German, Italian, Norwegian, Portuguese, Spanish, Swedish, Turkish and Chinese (Simplified), with more languages added over time. Apple Intelligence is available in most regions, including the European Union, on supported devices and software — but individual features, languages and Siri capabilities can vary by country, language and iOS version.

Check Apple's current feature-availability page and your iPhone Settings for the latest availability in your country.

Bottom line: if the toggle is missing despite having a supported iPhone, mismatched or unsupported languages are one of the most common causes.

Writing Tools is one of the most-used Apple Intelligence features, available in almost any text field.

4. What Apple Intelligence Can Do on iPhone

Once enabled, Apple Intelligence adds a set of features across apps you already use, rather than a single standalone app. Availability varies by language, region and software version.

• Writing Tools: select text in supported apps to proofread, rewrite or summarise, with preset tone options. Availability varies by language, region and software version.
• Notification summaries: condenses longer notification threads into a shorter summary. Availability varies by language, region and software version.
• Clean Up in Photos: helps remove distracting background objects from photos. Availability varies by language, region and software version.
• Natural-language photo search: search your photo library using descriptive, everyday language. Availability varies by language, region and software version.
• Siri improvements: Apple Intelligence can enhance Siri with improved language understanding and access to Apple Intelligence features. The availability of particular Siri capabilities may vary by language, country and software version.

Bottom line: these features work inside apps you already use daily — exactly which ones are available to you depends on your iPhone, language and current iOS version.

5. Apple Intelligence Not Showing Up? Try These Fixes

If you've gone to Settings and can't find Apple Intelligence & Siri at all, or the toggle appears greyed out, work through these in order:

1. Confirm your iPhone model is compatible (iPhone 15 Pro or later, or iPhone 16 and later).
2. Update to the latest available iOS version.
3. Check you have enough available storage (around 7GB is needed).
4. Check your device language and Siri language match and are supported.
5. Restart your iPhone.
6. Check Apple's current availability page for your country.
7. Check whether the specific feature you want requires a particular region, language or iOS version.

Bottom line: working through this list in order usually identifies the issue quickly — model, software version and language account for most cases.

6. How Much iPhone Storage Does Apple Intelligence Need?

Apple states that Apple Intelligence requires about 7GB of on-device storage for its models. This is a one-time download rather than an ongoing storage cost, but available storage can vary once system files, apps and media are taken into account.

Check what's free under Settings, then General, then iPhone Storage before attempting setup if your phone is already close to full. If you're choosing a new iPhone and plan to use Apple Intelligence heavily alongside photos, apps and downloaded media, it's worth building in some headroom — storage cannot be upgraded after purchase.

Bottom line: 7GB isn't large on a modern iPhone, but it's worth checking if you're setting up an older, fuller device.

Checking compatibility and storage before setup helps Apple Intelligence run smoothly from day one.

7. Final Verdict

Learning how to set up Apple Intelligence on iPhone really comes down to three things: confirming your device qualifies, updating to a supported iOS version, and flipping one toggle in Settings. Current availability and feature support can change with future iOS updates, so it's worth checking Apple's official pages if a specific feature matters to you.

Compare Apple Intelligence-compatible iPhones, choose the storage and colour that suit your daily routine, and check the relevant product page for current pricing, delivery options and warranty information before ordering.
