DirectWA or Direct WP is a productivity app that allows users to chat on WA without saving phone numbers. It also generates whatsapp direct message link, which you can share anywhere, and when the user clicks on it they can contact you directly.

It is rather inconvenient to add someone to your contacts, only to send them a single WhatsApp text. WA Direct allows you to send WhatsApp messages directly to the phone number, without saving it to your contacts.
Just select the appropriate country code, enter the receiver's phone number and the text message that you want to send, then click on the Send button. You will be redirected to the WhatsApp chat for that number, even though the contact is not saved on your device.

WhatsApp has a feature that allows people to create links, so any user can click and start a conversation (chat) directly with the person who created the link. This functionality is called "click to chat" and as you don’t have to save anyone’s phone number to message them, it simplifies interaction.

Even so, creating WhatsApp links is not user friendly and occasionally takes more time than expected. There’s where DirectWA comes in, we provide a tool that you can use to generate shortened WhatsApp links. This will increase your chat conversions, and it’s free!
