自動メンバー追加くん is a free Chrome add-on designed to enhance efficiency in managing members within Chatwork rooms. This tool automates the process of adding multiple members to various rooms with just one click. Key features include automatic retrieval of contact and room lists via the Chatwork API, bulk addition of members to multiple rooms, a room set feature for saving commonly used member combinations, and a search filter to quickly select members and rooms.

The add-on is particularly useful for administrators who need to add new employees to multiple rooms or consistently add the same members for various projects. To use the tool, users must set up an API token initially, retrieve room and member lists, select the desired members, choose the target rooms, and execute the addition. Note that during execution, users should avoid interacting with other Chatwork tabs.
