Apple Intelligence Writing Tools: Complete Guide to Smarter Writing on iPhone, iPad, and Mac

Struggling to find the right words for important emails or messages? Apple Intelligence Writing Tools brings on-device AI assistance to your everyday writing, helping you compose, rewrite, and proofread messages instantly—without sharing your content with external servers.

What is Apple Intelligence Writing Tools?

Apple Intelligence Writing Tools is an on-device AI feature built into iPhone, iPad, and Mac that helps you improve your writing instantly. Think of it as a personal writing assistant that understands context and works entirely on your device—no content is sent to Apple’s servers or any external service.

These tools work across Mail, Messages, Notes, and most third-party apps through three core modes:

• Compose – Start from scratch or expand rough ideas into complete sentences. Great for when you know what you want to say but struggle with phrasing.

• Rewrite – Take existing text and improve it by adjusting tone (Friendly, Professional, or Concise). Perfect for emails that need a different voice.

• Proofread – Catch grammar, spelling, and punctuation mistakes automatically, with one-tap corrections for easy fixes.

Unlike general-purpose AI tools, Apple Intelligence stays on your device, meaning your personal messages, email drafts, and notes never leave your iPhone, iPad, or Mac. Apple’s private processing technology analyzes what you’ve written and suggests improvements based on context.

Current as of iOS 18.1+ / iPadOS 18.1+ / macOS 15.1+ (April 2026)

Why Use This Feature?

• Save Time on Writing Tasks – Instead of rewriting emails from scratch, let Apple Intelligence handle the heavy lifting. Compose emails in seconds, not minutes.

• Write with Confidence – Don’t worry about grammar or tone mistakes. Proofread catches errors before you send, and Rewrite helps you strike the right tone for any situation (professional meeting request vs. friendly note to a colleague).

• Improve Communication – Your message gets clearer and more impactful. Whether you’re refining a casual message or a formal email, Writing Tools adapt to your needs.

• Privacy-First AI – Everything happens on your device. Your emails, messages, and notes never travel to any external server or AI system—Apple’s on-device processing handles everything.

Things to Consider

• Device Requirements – Apple Intelligence Writing Tools only work on iPhone 15 Pro/Pro Max, iPad Pro/Air with M1 chip or newer, or Mac with M1 or newer processor. Older devices won’t have access to this feature.

• Software Update Needed – You must install iOS 18.1, iPadOS 18.1, or macOS 15.1 (or later). If your device meets the hardware requirements but you haven’t updated, Writing Tools won’t appear.

• Review AI Suggestions Carefully – While Apple Intelligence is accurate, it doesn’t know your specific context the way you do. Always review suggestions for professional or sensitive emails before sending to ensure the tone and content match your intent.

How to Use Apple Intelligence Writing Tools: Step-by-Step Setup

Step 1: Verify Your Device is Compatible

Apple Intelligence Writing Tools only work on newer Apple devices. Check what you’re working with:

1. On your device, open Settings > General > About
2. Look for your device model name (example: “iPhone 15 Pro”) and your current software version
3. Compatible devices are:
   • iPhone 15 Pro or iPhone 15 Pro Max
   • iPad Pro or iPad Air with M1 chip or newer
   • Mac with M1 chip or newer processor
4. If your device isn’t on this list, Writing Tools won’t be available

Step 2: Update Your Software

Apple Intelligence requires the latest software. Even if your device is compatible, older software versions won’t have Writing Tools:

1. Open Settings > General > Software Update
2. Tap Install Now if an update appears (you need iOS 18.1 or later, or equivalent iPadOS/macOS)
3. Your device will restart during the update—let it complete fully before using Writing Tools
4. After restarting, go back to Settings and confirm your version shows 18.1 or higher

Step 3: Enable Apple Intelligence

Apple Intelligence is off by default—you need to turn it on:

1. Open Settings > Apple Intelligence & Siri
2. Tap the toggle next to “Apple Intelligence” to turn it on (it will turn blue)
3. A privacy notice appears explaining that on-device processing keeps your data private—tap “Enable Apple Intelligence” to confirm
4. Wait a moment while your device prepares (it may download necessary files)
5. Once enabled, you’ll see “Apple Intelligence is on” at the top of the screen

Step 4: Open Mail and Start Composing

Now you’re ready to use Writing Tools. We’ll use Mail as an example (Writing Tools work the same way in Messages, Notes, and other apps):

1. Open the Mail app
2. Tap the compose button (pencil icon in a circle, usually in the bottom right corner)
3. Fill in the To, Subject, and start typing your message—or leave the message field blank if you want Apple Intelligence to compose from scratch
4. Don’t worry about perfect wording; you’ll refine it in the next steps

Step 5: Access the Writing Tools Menu

This is where the magic happens:

1. In the message body field, press and hold for 1-2 seconds (or look for a sparkle/AI icon—its exact location depends on your app)
2. A context menu appears with several options
3. Tap “Writing Tools” (it may also say “Apple Intelligence” or show a sparkle icon)
4. Three options now appear: Compose, Rewrite, and Proofread

Step 6: Choose Your Mode Based on Your Need

Each mode serves a different purpose:

If You’re Starting From Scratch (Compose Mode):

1. Make sure your message field is empty or has just a few words/ideas
2. Tap “Compose” from the Writing Tools menu
3. A suggestion appears—read it to see if it matches what you want to convey
4. Apple Intelligence expands your rough outline into full sentences
5. Example: Type “Meeting next week about Q2 budget” → Writing Tools might generate: “I’d like to schedule a meeting next week to discuss our Q2 budget. Would Tuesday or Wednesday afternoon work for you?”

If You Want to Change the Tone (Rewrite Mode):

1. First, write out your message (even if it’s rough)
2. Select the text you want to rewrite (or leave it all selected)
3. Tap “Rewrite” from the Writing Tools menu
4. Choose your desired tone:
   • Friendly – Casual, warm, and conversational
   • Professional – Formal, clear, and business-appropriate
   • Concise – Brief and to-the-point
5. Writing Tools instantly rewrites your selection in that tone
6. Example: “Can you send me the files?” becomes “Would you mind sharing those files when you have a moment? Thanks!” (Friendly) or “Please provide the requested files.” (Professional)

If You Want to Fix Grammar and Spelling (Proofread Mode):

1. Type or paste your complete message
2. Tap “Proofread” from the Writing Tools menu
3. Writing Tools scans for grammar, spelling, and punctuation errors
4. Each issue appears highlighted with a suggestion
5. You can tap each suggestion to accept it or leave it as-is
6. Example: “Their going to the meeting” → Writing Tools suggests “They’re going to the meeting”

Step 7: Review and Customize Suggestions

Apple Intelligence makes suggestions, but you’re in control:

1. Read through the entire suggested text or corrections
2. If you like a suggestion, tap “Accept” or just proceed (accepted text replaces your original)
3. If you don’t like something, manually edit it—select the text and retype it your way
4. You can delete entire phrases, reorder sentences, or change individual words
5. Pro tip for professional emails: Always manually review AI suggestions to ensure they match your specific context and company style
6. Don’t send a message just because Apple Intelligence suggested it—if something doesn’t feel right, change it

Step 8: Send Your Email

Once you’re satisfied with your message:

1. Review the complete email one final time (especially for important professional communication)
2. Check that the To field is correct and Subject is clear
3. Tap “Send” to deliver your message
4. Your email goes out with all the improvements you and Apple Intelligence made
5. Note: Writing Tools only help you compose—they have no effect on email delivery or how recipients see your message

Pro Tips for Getting the Most from Writing Tools

Be Specific When Using Compose Mode Instead of starting completely blank, give Apple Intelligence a direction. Rather than leaving the message empty, type something like “Meeting request for project timeline discussion” or “Thank you message for helping with the presentation.” This context helps Writing Tools generate more relevant and appropriate suggestions.

Use Rewrite to Test Different Approaches Don’t settle on your first version. Use Rewrite multiple times with different tones to see which version works best. Try Professional, then Friendly, then Concise—you’ll often discover better ways to phrase things you hadn’t considered.

Always Review Sensitive Professional Emails For emails about budgets, performance reviews, contracts, or sensitive topics, manually review every suggestion. Apple Intelligence doesn’t know your company’s specific context, politics, or relationships. A technically correct suggestion might miss important nuance.

If Writing Tools Doesn’t Appear Try these troubleshooting steps:

1. Verify Apple Intelligence is enabled in Settings > Apple Intelligence & Siri
2. Check that your app (Mail, Messages, Notes) is fully updated in the App Store
3. Restart your device and try again
4. Confirm you’re using iOS 18.1+ (or equivalent) and a compatible device

Use Proofread as Your Final Safety Check Before sending any important message, run Proofread as your last step. It catches small errors that your eyes might miss, especially in longer emails.

Apple Intelligence Writing Tools transform how you write on iPhone, iPad, and Mac by combining the convenience of AI assistance with the privacy of on-device processing. Whether you’re composing emails from scratch, adjusting tone for different audiences, or catching grammar mistakes, these tools make you a more efficient and confident communicator. Start with your next email and discover how much time and stress you can save.
