Yanling is a free Chrome add-on designed for content creators, facilitating comment management across popular platforms like Xiaohongshu, Bilibili, and Douyin. This tool provides a sidebar that aggregates visible comments from supported sites, allowing users to efficiently read and respond to them. It synchronizes with the current tab and updates according to page changes. Users can differentiate between their comments and others, and the sidebar merges with cloud data to display intent tags and reply statuses, requiring user login and internet connection.

The core feature, known as Zhiyuan, allows users to view and refresh comment lists that highlight as the page scrolls. It offers filters for comments and AI-generated reply suggestions that can be easily inserted into the site's reply box. Users can also save frequently used AI phrases for quick access, manage their accounts, and customize settings within the sidebar. Yanling is compliant with platform rules and ensures secure communication with its servers.
