New WhatsApp AI tool will help you write better messages within a chat

WhatsApp today launched Writing Help, an AI assistant that offers private suggestions to sharpen the tone, clarity, or style of your messages on iOS and Android. Let’s dive in.

No more writer's block on chats

The tool sits in the message field and waits politely while you type. Nothing is processed until you tap the new pencil icon, and the app will not see your words until that tap.

Once asked, the system returns several rewritten options in different tones including rephrase, professional, funny, supportive, and proofread. You can copy an option, edit it further, or stick with your original text.

Recipients will not know that Writing Help was used because suggestions merge seamlessly into normal chat flow. The vibe here is simple. If you need a quick professional polish, a lighter tone for friends, or more empathetic phrasing when someone needs support, Writing Help offers tidy options.

The feature runs on Private Processing so every request is encrypted and routed anonymously, and neither WhatsApp nor Meta can read or store your draft or the suggestions it produces.

WhatsApp first tested this in a small beta rollout and today is expanding access to more users in English in the United States and several other countries with broader language support planned later this year. Turning on Writing Help requires opting in via app settings so the feature never activates without your say so.

In case you want to dig deeper, Meta also points to engineering notes and a technical white paper.
