Perhaps you meant to sound encouraging, but it came across as demanding.
Maybe you drafted a professional update that read like a casual chat.
In today’s fast-paced digital communication, getting the tone right is critical, especially when sending work or business-related messages on platforms like WhatsApp.
An unintended nuance can derail a deal or create unnecessary friction with a coworker or client.
This is a common and frustrating problem.
Here's a Cool Tip: Let AI rewrite your WhatsApp Messages.
Fortunately, WhatsApp now offers a smart solution built right into the composition window.
Feature Explanation
WhatsApp is rolling out an AI writing assistant, an on-device feature designed to help users refine the tone and polish the phrasing of their drafted messages before they are sent.
It uses a small language model that runs locally on your phone, enhancing privacy.
When you type a message, the AI offers suggestions to rewrite or rephrase the text.
This feature is not a grammar check; it is a communication tool.
The feature works by analyzing your message draft and then presenting alternative ways to express the same idea, focusing on changing the message's style and tone.
For example, a curt one-line reminder can be softened into a polite request.
A complex explanation can be simplified for clarity.
This matters because WhatsApp is increasingly used for official business communications, and maintaining a professional or appropriate tone is key to successful interaction.
What You’ll Gain
- Clarity: Ensure your message is easy to understand without ambiguity.
- Tone Control: Effortlessly switch between professional, casual, formal, or friendly tones.
- Time Savings: Quickly polish drafts without manually composing multiple versions.
- Fewer Misunderstandings: Reduce the chance of an unintended meaning causing friction.
Step-by-Step Instructions
Here's how to do it.
