Chatra is a live chat software that allows your customers to chat with you and have their questions answered in real time. Chatra enables you to engage proactively with your customers, facilitates group chats for optimum team collaboration on support, and provides chat previews for your team members to get inside the heads of your customers, viewing their chat questions before your customers hit send.
