WhatsApp is trying out a new feature called Guest Chats, which lets people chat with someone without having a WhatsApp account. You don’t need to sign up or download the app to use it. All you have to do is open a special chat link and start messaging right away — great for short, quick chats. Right now, this feature only works for sending text messages, but it might make WhatsApp easier to use and more accessible without the need for signing up.
