Apple Writing Tools Limitations: What It Can't Do

7 Limitations of Apple Writing Tools

1. Only Works in Select Apps

This is the biggest limitation. Apple Writing Tools only appears in apps that explicitly integrate with it — primarily Apple's own apps (Mail, Notes, Pages, Safari, Messages) and a handful of updated third-party apps.

If you use Slack, Discord, VS Code, Chrome, Firefox, Notion, Obsidian, Bear, or Terminal — Writing Tools simply doesn't exist. You're on your own.

Many users report seeing "Writing Tools is unavailable" in apps where they expected it to work. Apple requires developers to explicitly adopt the API, and most third-party apps haven't.

2. Grammar Detection Is Basic

Apple's "Proofread" feature catches basic spelling and simple grammar errors, but misses nuanced issues that dedicated grammar checkers catch:

• Subject-verb agreement in complex sentences
• Commonly confused words (affect/effect, their/there)
• Comma splices and run-on sentences
• Inconsistent tense usage
• Wordiness and passive voice

For professional or academic writing, Apple Writing Tools isn't accurate enough to rely on.

3. Rewrite Changes Your Meaning

The "Rewrite" feature is one of the most criticized aspects. It tends to make text more generic — stripping personality, changing tone, and sometimes altering the actual meaning. Writers report that rewritten text sounds "AI-generated" and loses their voice.

4. No Translation

Apple Writing Tools doesn't include translation. If you write in multiple languages or need to translate text as part of your workflow, you need a separate tool.

5. Requires Apple Silicon + macOS 15

Writing Tools requires macOS Sequoia (15+) on an Apple Silicon Mac with at least 8GB of RAM. If you have an Intel Mac — even a recent one — Writing Tools is completely unavailable. This excludes millions of Mac users.

6. Slow and Disruptive Workflow

Using Writing Tools requires: select text → right-click → hover over "Writing Tools" → choose an option → wait for results → review in a separate panel → accept or reject. This multi-step process interrupts your writing flow, especially when you need to correct text frequently.

7. English-Centric

Most Writing Tools features work best (or only) in English. Proofreading support for other languages is limited, and the quality drops significantly for non-English text.

What to Use Instead

If Apple Writing Tools isn't enough for your needs, here are alternatives that solve these limitations:

Grammarly — Best for Browser Writing

If you primarily write in browsers and Google Docs, Grammarly remains the most comprehensive option. But it shares some of Apple's limitations — it doesn't work in all Mac apps either. See our full comparison.

LanguageTool — Best Open Source Option

LanguageTool supports 30+ languages and has an open-source core. Good for multilingual writers, but system-wide support on Mac is limited. See our comparison.

When Apple Writing Tools Is Still Worth Using

Despite its limitations, Apple Writing Tools makes sense if you meet certain narrow conditions. For everyone else, a dedicated grammar checker for Mac is a better choice. Here's when it works:

• Only write in Apple apps (Mail, Notes, Pages)
• Only need basic spell-checking
• Want the "Summarize" feature for long emails
• Prefer 100% on-device processing

For everything else, a dedicated grammar checker like FlowWrite fills the gaps Apple left.
