bilicrab is a Chrome add-on developed by slotDumpling that allows you to convert the danmaku (comment) format in Bilibili videos to a vertical layout. With this add-on, the danmaku will be displayed in a traditional vertical format, scrolling from the bottom of the screen to the top.

This add-on supports converting the danmaku format in regular Bilibili videos, but does not currently support live streaming videos. With bilicrab, you can experience a unique way of viewing danmaku content, making it easier to read and follow along with the comments.

Please note that bilicrab is free to use and is available on the Chrome platform. It falls under the category of Browsers and is classified as an Add-ons & Tools subcategory. Enjoy your Bilibili videos with the converted vertical danmaku format provided by bilicrab!
