The Facebook Auto-Chat Robot can automatically send various types of messages, including double-click sending, looping sending, or repeating single messages. It supports message editing, allowing you to customize message sequences for automatic chatting with various online friends. You can also change the chat frequency, with the fastest being once per second.
If you are an online customer service representative, you can set some promotional messages so that even when you are away from the computer, you can still provide useful tips to your users, which is much more flexible than the built-in reply function. Additionally, you can use your defined messages to dismiss some friends you don't want to chat with or to penalize those who are hostile towards you.
