Desktop WA - online messenger is a Chrome extension that provides convenient access to your WhatsApp messages. It allows you to receive notifications for new messages and acts as a non-official WhatsApp app.

One of the key features of Desktop WA - online messenger is that it doesn't require a desktop version of WhatsApp to be installed on your PC. Instead, it functions as an extension on your browser, mirroring all your conversations and messages from the app on your phone. This enables you to view and reply to messages on your PC or Mac using your computer's keyboard.

The extension also enables always-on desktop notifications, meaning that Chrome will run in background mode permanently, keeping track of your WhatsApp notifications and showing them instantly. You can simply click on the notifications to go directly to the relevant chat.

With its comprehensive web client right in your browser's toolbar popup UI, Desktop WA - online messenger provides a seamless and accessible way to stay connected on WhatsApp. It also notifies you, via badge icon text, whenever there is any activity within your chat list on the web.

Please note that the official WhatsApp software is only released for smartphones and web. Desktop WA - online messenger is an independent project developed by Thu Nga Trịnh and is not related to WhatsApp IInc, the corporation behind WhatsApp.
