Autofill in GoogleChat is a Chrome extension developed by tatsu. This free tool automatically inputs text in any designated space within GoogleChat. It is designed to assist users by entering predefined text or mentions in spaces where standard phrases or mentions are frequently used.

With Autofill in GoogleChat, users can streamline their messaging process by predefining URLs and texts in a convenient pop-up window. This extension is particularly useful for spaces where users want to consistently input specific text or mentions, such as "@all" mentions. By copying and registering the required span element from the developer tools, users can easily automate these inputs in GoogleChat.
