What Are Apple Writing Tools?

Apple Writing Tools are part of Apple Intelligence, Apple's personal intelligence system available on supported iPhone, iPad, and Mac devices.

Rather than replacing your keyboard, Writing Tools appear when you select text inside compatible apps.

You can quickly:

• Proofread text
• Rewrite sentences
• Make writing friendlier
• Make writing more professional
• Make text more concise
• Summarize long passages

For many users, these built-in tools eliminate the need to copy and paste text into separate AI apps.

If your writing needs are occasional—replying to emails, editing notes, or polishing messages—Apple Writing Tools provide a convenient solution without installing additional software.

Feature-by-Feature Comparison

AI Writing Assistance

Both Apple Writing Tools and RewriteMate help improve your writing, but they approach the task differently.

Apple Writing Tools

Apple focuses on making existing text better.

You write first.

Then select the text.

Then choose an action such as:

• Rewrite
• Friendly
• Professional
• Concise
• Proofread
• Summarize

The experience feels polished and integrates naturally into supported apps.

RewriteMate

RewriteMate focuses on giving you more ways to transform your writing.

Instead of only offering preset options, it lets you quickly:

• Rewrite professionally
• Rewrite casually
• Make messages more persuasive
• Simplify explanations
• Improve readability
• Adjust confidence
• Add empathy
• Expand or shorten content
• Use your own saved AI prompts

This flexibility is particularly valuable for users who communicate with different audiences throughout the day.

---

Keyboard Experience

One of the biggest differences is how you interact with AI.

Apple Writing Tools

Apple Writing Tools are not a keyboard.

Instead, they appear after selecting text.

Typical workflow:

1. Write your message.
2. Highlight the text.
3. Open Writing Tools.
4. Choose an option.
5. Replace the original text.

This works well for occasional edits but adds a few extra steps when you frequently rewrite messages.

RewriteMate

RewriteMate integrates AI directly into your keyboard.

Instead of leaving your typing flow, you simply tap the desired action while composing your message.

For users who spend hours every day writing on their phones, this keyboard-first approach can feel significantly faster.

---

App Compatibility

Compatibility matters because most people switch between several apps throughout the day.

Apple Writing Tools

Writing Tools are available in supported apps on compatible Apple devices.

The exact experience can vary depending on the app and whether it supports Apple's writing features.

RewriteMate

Because RewriteMate functions as an AI keyboard, it works in most places where the iPhone keyboard appears.

Common examples include:

• Messages
• Mail
• Gmail
• Outlook
• Slack
• WhatsApp
• Telegram
• Notes
• LinkedIn
• Instagram
• X
• Facebook

For users who constantly move between communication apps, this consistency can make AI assistance feel more accessible.

---

Grammar Correction

Grammar checking is an important feature regardless of which tool you choose.

Apple Writing Tools include proofreading that identifies spelling mistakes, grammar issues, and awkward phrasing.

RewriteMate also provides grammar correction, but pairs it with broader AI rewriting capabilities.

---

Custom AI Commands

This is where RewriteMate separates itself from Apple's built-in solution.

Apple Writing Tools provide a fixed set of actions.

RewriteMate allows users to create reusable AI commands tailored to their workflow.

Examples include:

• Rewrite like my CEO
• Friendly customer support reply
• Turn this into a LinkedIn comment
• Simplify technical writing
• Create executive summary
• Make this persuasive
• Rewrite for non-native English readers

These saved commands eliminate repetitive prompting and help maintain a consistent writing style.

If you regularly write similar emails or messages, custom commands can save significant time.

---

Translation & Multilingual Writing

Many professionals communicate across multiple languages every day.

RewriteMate combines translation with AI rewriting, allowing users to translate content while preserving natural tone.

For example:

Write in English.

Translate to Spanish.

Then make it sound more professional.

Everything happens from the keyboard.

Apple Writing Tools also support multilingual writing improvements in supported languages, but RewriteMate's keyboard-first workflow can be more convenient for users who frequently switch languages while messaging.

---

Privacy & On-Device Processing

Privacy is one of Apple's strongest selling points.

Apple Intelligence is designed to process many requests directly on your device whenever possible. For more complex requests, Apple uses Private Cloud Compute, a system intended to extend AI capabilities while maintaining strong privacy protections.

RewriteMate, as a dedicated AI writing tool, focuses on providing AI-assisted writing features while handling requests securely according to its service architecture.

If on-device processing is your highest priority, Apple's built-in approach may be especially appealing.

If your priority is productivity and advanced writing workflows, RewriteMate provides a richer feature set while still emphasizing responsible handling of user content.
