Introducing Pakku: a Chrome extension designed to filter out spammy comments on Bilibili videos, giving you a clean and enjoyable viewing experience. Pakku merges repetitive comments, reducing the obstruction on the screen and eliminating the need to constantly rewind and catch missed content. It can block the majority of duplicate comments, making up 30% to 80% of the total comment pool. Additionally, Pakku offers enhancements to the HTML5 player, such as a comments display box, comment density chart, and the ability to view comment senders. All operations are performed locally, with no collection of user account information or viewing history. The extension is open-source and also available for Firefox on addons.mozilla.org under the name "pakku."
