By the end of this guide you'll have Apple Intelligence switched on, know how to ask Siri for a quick draft or a short summary, and feel confident using the new AI‑powered suggestions in Messages and Mail. This guide is for anyone who picks up an iPhone and wants a smarter daily helper without needing any coding knowledge.

💡 Tip: tap a step’s number when you finish it — a green tick appears and your browser remembers how far you got.

✅ Before you start
  • iPhone model – Only iPhone 15 Pro, iPhone 15 Pro Max, iPhone 16, iPhone 16 Plus, iPhone 16 Pro, iPhone 16 Pro Max, or iPhone 16e support Apple Intelligence. The regular iPhone 15 and iPhone 15 Plus do not have this feature.
  • iOS version – You need iOS 18.1 or later. Earlier versions do not include Apple Intelligence.
  • Language setting – Apple Intelligence requires your device language to be set to English (US). Go to Settings → General → Language & Region → iPhone Language and select English (US).
  • Apple ID – the same account you use for the App Store; you'll need to be signed in.
  • Internet connection – a Wi‑Fi or mobile data link is required for the first activation.
  • Time needed – roughly 10 minutes total: a few minutes to update, a couple of minutes to enable the feature, and a few minutes to try a sample prompt.

You'll know you're ready when your iPhone shows the current iOS version (Settings → General → About → Version) as 18.1 or later.

Step 1 of 6

Update to the latest iOS

Tap Settings, then General, and finally Software Update. You'll see a screen that either says "Your software is up‑to‑date" or shows a button labeled Download and Install. Press the download button; the phone will download the update, verify it, and then ask you to restart.

💬 Example*No typing needed for this step.*
✅ You'll know it worked when

the phone restarts and the About page now displays a version number starting with 18.1 or higher.

🔄 If it looks different

If you don't see a Software Update option, look for a gear‑icon labeled Settings in the lower‑right corner of the home screen – the wording may vary by region.

Set language to English (US)

Apple Intelligence only works when your device language is set to English (US). Go to Settings → General → Language & Region. Tap iPhone Language and select English (US). Confirm any prompts to apply the change.

💬 Example*If you prefer another language, Apple Intelligence won't appear in your settings.*
✅ You'll know it worked when

"English (US)" appears as your selected iPhone language.

Turn on Apple Intelligence in Siri settings

Open Settings again, scroll down until you find Apple Intelligence & Siri, and tap it. (On some iOS versions, it may be under Siri & Search.) The screen will show a switch labeled Apple Intelligence or Enable Apple Intelligence. Flip that switch on. If the Apple Intelligence option is missing, first confirm your device supports it and is running iOS 18.1 or later. You may need to scroll down to find it, or it could be nested under a submenu on some devices.

💬 Example*No text entry required.*
✅ You'll know it worked when

the switch turns green and a brief banner appears saying "Apple Intelligence is now active".

Step 4 of 6

Configure the type of suggestions you want

While still in Apple Intelligence & Siri settings (or Siri & Search), look for Writing Tools or Intelligent Suggestions. Here you'll see options for Message Drafts, Mail Summaries, and App Suggestions. Enable the features you want to test (for a first test, enable Message Drafts and Mail Summaries). Some iOS versions show toggles, others show checkboxes — either way, make sure the feature is turned on.

💬 Example*No typing required.*
✅ You'll know it worked when

each option you selected displays a green highlight or a checkmark beside it.

Step 5 of 6

Use Writing Tools to draft a reply in Messages

Open the Messages app and start a new conversation or select an existing one. Tap the text field so the keyboard appears, then look for the Apple Intelligence icon (a sparkling star or the Siri logo depending on your iOS version) near the keyboard. Tap it and try a prompt like "Draft a friendly reply saying I'll be there at 3 pm."

✅ You'll know it worked when

suggested text appears that you can tap to insert into your message.

🔄 If it looks different

If you don't see the icon, you can also activate Siri by holding the side button or saying "Hey Siri" out loud, then ask: "Can you help me draft a reply for my message?"

💬 Try typing this"Hey Siri, help me draft a reply saying I'll be there at 3 pm."➤

Use Apple Intelligence to summarize an email in Mail

Launch the Mail app and open any email that contains a few paragraphs. If Apple Intelligence is enabled, you'll see a Summarize button or icon at the top of the email (or in the reply area). Tap it. If the button isn't visible, look for the Apple Intelligence icon in the toolbar, or try long-pressing on the email and selecting Summarize from the context menu.

💬 Example*Tap the summarize button — no typing needed.*
✅ You'll know it worked when

a concise summary of the email appears, usually in one or two sentences.

⚠️ Common mistakes
  • Using a non-Pro iPhone model: Apple Intelligence only works on iPhone 15 Pro, iPhone 15 Pro Max, iPhone 16 series, and later Pro models. If you have a regular iPhone 15 or iPhone 15 Plus, the feature won't be available — consider upgrading to a supported model.
  • Skipping the iOS update: The Apple Intelligence switch only appears on iOS 18.1 or later. If you miss the update, the option won't show — go back to Step 1 and ensure the version is 18.1 or higher.
  • Wrong language setting: Apple Intelligence requires English (US). If your iPhone is set to another language, the feature won't appear even on supported devices.
  • Leaving toggles off: The feature is enabled but the specific suggestions (Message Drafts, Mail Summaries) stay disabled. Re‑visit Step 4 and double‑check each option is turned on.
  • Expecting automatic sending: Apple Intelligence can draft or summarize text, but it cannot press "Send" for you. Always review the generated content before sending.
🚀 Try it now

Open Messages, activate Siri (hold the side button or say "Hey Siri"), and ask: "Can you help me draft a reply saying I'll be there at 3 pm?" If suggested text appears, you've completed the core activation — now you can explore other prompts at your own pace.
