##### How to Use

Go to the page, input a message with special text, and send the message. The text in the chat list is automatically identified and marked with special text. Currently, the following types of text can be recognized: phone number, link, email address, and address. Addresses need specific address information to be identified. The recognized text will turn blue and be underlined.
