Mesej Je is a Chrome extension developed by kusyuk that allows users to start a Whatsapp Web chat conversation without any hassle. With this extension, users can directly message a Whatsapp number without the need to save the number to their contact list. This makes contacting unsaved numbers on Whatsapp Web much easier.

One of the key features of Mesej Je is the ability to open a chat message for unsaved numbers on Whatsapp Web. This extension simplifies the process of contacting someone with a single-time phone number. It eliminates the need to save the number first, saving users time and effort.

Originally an Android business tools app for Whatsapp (WA) users, Mesej Je has now come to Chrome Extension, bringing its full functionality to desktop users. However, please note that Mesej Je relies on the official Whatsapp application to verify a phone number. Depending on your internet connection and the refresh rate of the contact list, you may occasionally experience an error message stating "number not registered".

Privacy is an important aspect of Mesej Je. The developers emphasize that the app does not condone any act of spamming or privacy abuse towards other users. Users are advised to use this app with dignity and respect towards others.
