Youtube Livechat Danmaku Helper

About

# 🚀 Experience YouTube Live streams like never before!

YouTube Livechat Danmaku Helper overlays live chat messages directly onto the video player as scrolling "Danmaku" (barrage) comments. This allows you to watch the video and the chat interaction simultaneously in fullscreen, without needing a separate chat window.

## ✨ KEY FEATURES:

### 🚀 High Performance Engine
Powered by HTML5 Canvas and GPU acceleration. It renders smooth 60fps animations without slowing down your browser, even with thousands of concurrent messages.

### 🎨 Fully Customizable
Personalize your viewing experience with a modern, pink-themed control panel:
- **Fonts:** Support for English, Chinese (Sim/Trad), Japanese, Korean, and Thai.
- **Size & Speed:** Adjust text size, scroll speed, and opacity.
- **Display Area:** Limit danmaku to the top/bottom half or use full screen.
- **Smart Anti-Overlap:** Intelligent algorithm to prevent text overlapping.

### 🛡️ Privacy First & Open Source
- **Zero Data Collection:** We do not collect or upload any of your personal data.
- **Local Processing:** All chat messages are processed locally in your browser.
- **Open Source:** This project is fully open source on GitHub. You can inspect the code yourself!

### 🌐 International Support
The interface automatically adapts to your browser language (English, Chinese, Japanese, Korean, French, Thai).
