WhatsApp is testing AI message rewriting tool with multiple tone options

Tone policing just got easier. WhatsApp is developing an AI-powered text rewriting tool that will help users adjust the style and tone of their messages, from proofreading to adding humor or sarcasm. This feature represents a careful integration of AI capabilities into the world’s most popular messaging platform, showing how Meta is strategically expanding AI functionality in a service used by billions of people globally.

The big picture: Meta is developing an AI-based text rewriting feature for WhatsApp that would allow users to modify the style and tone of their messages before sending.

• Code in the latest WhatsApp beta (v2.25.8.5) reveals a new Pencil button that would appear above the send button when users type in the text box.
• Tapping this button would open a text editor that uses AI to help rewrite messages in different styles, though the feature is clearly still under development.

Key details: The AI rewriting tool will seemingly offer multiple style options to transform messages.

• According to code in the app, available rewriting styles will include: Funny, Proofread, Puns, Rephrase, Sarcastic, Shorter, Spooky, and Supportive.
• The Proofread option appears designed to check spelling and grammar, while other options would adjust the overall tone and style of messages.

Why this matters: Meta is proceeding carefully with AI integration into WhatsApp, recognizing that even small changes impact billions of users worldwide.

• This measured approach to implementing AI features reflects the company’s understanding of WhatsApp’s critical role in global communications.
• The feature shows how consumer-facing AI tools are evolving beyond creation to include refinement and personalization of user-generated content.

Behind the scenes: The feature was discovered through an APK teardown, which examines code in development versions of the app.

• While APK teardowns can reliably predict upcoming features, there’s no guarantee this specific implementation will make it to a public release.
• Currently, tapping the new option only opens an empty bottom sheet, indicating the feature is still in early development stages.
