Writing Tools
Writing Tools provides AI-powered text composition and editing directly within Apple apps like Pages, Mail, and Messages.
Why It Exists
Users spend significant time writing and editing text across apps. Writing Tools addresses the need for intelligent text assistance without switching contexts or sharing sensitive content with cloud services.
How It Works
Writing Tools leverages Apple's on-device language models to generate and refine text based on user prompts. The feature integrates deeply with the iOS text system, allowing users to rewrite, proofread, and summarize text without leaving their current app. All processing happens on-device using the Apple Neural Engine, ensuring user data remains private.
Everyday Use Cases
- Rewrite an email to sound more professional
- Summarize a long document quickly
- Proofread a text message before sending
- Generate creative content for social media
User Workflow
- Select text in any supported app
- Tap the Writing Tools icon or use the on-screen menu
- Choose an action: Rewrite, Proofread, Summarize, or Custom
- Review the AI-generated suggestion and tap to accept or edit
AI Processing Flow
On-device Apple Intelligence model processes text locally. No data leaves the device for core writing tasks.
Inputs / Outputs
Inputs:
- Selected text
- User prompt
Outputs:
- Rewritten text
