BiliScope is a Firefox extension that serves as a comprehensive assistant for Bilibili users. It enhances the browsing experience by providing detailed information cards when hovering over content creators' links. These cards display essential data including the creator's ID, level, follower relationships, and quick actions for following or blocking them. Additionally, users can view real-time details such as whether the creator is live, their follower and submission counts, and a summary of their video content, along with an interactive word cloud of video titles and descriptions.

The extension also enriches video watching by offering AI-generated summaries that allow users to jump to specific chapters within videos. It automatically displays dynamic updates and comment sections with geographical IP information. Users can add personalized notes for creators, which can be tagged for easier searches. The customizable tag colors and the option to highlight creator names in tag colors further enhance user engagement, making BiliScope a valuable tool for active Bilibili community members.
