YouTube LiveChat Flusher (Danmaku Chat) is a Chrome extension that superimposes bullet chatting (danmaku) on YouTube Live streams, replicating the popular chat style seen on platforms like niconico and bilibili. It works without displaying the traditional chat frame, allowing a seamless and immersive viewing experience.

Key features include the ability to pause and manually scroll individual messages, rendering of vote results during streaming, integrated message translation using Google Translate, and time-shift chat support. Users can customize animation duration, font settings, chat opacity, message display limits, emoji expressions, flow direction, and hotkeys. Additional controls offer filtering options and user-defined CSS to tailor the chat appearance. A user-friendly configuration panel is accessible via a gear icon.

This extension enhances engagement on YouTube Live by providing a visually dynamic chat overlay, ideal for viewers who enjoy interactive real-time commentary. It is currently under development, so occasional refreshes or switching to the mini player may be needed for optimal performance.

User reviews

Users find the add-on very effective, offering smooth, customizable Danmaku-style comments on YouTube live streams with useful features like translations. It works reliably and feels natural.

Cons

Some delay in comment loading time when opening live streams or archives.

When rewinding video with keyboard, a large number of comments rapidly display, cluttering the screen.
