About Youtube Livechat Danmaku Helper

# 🚀 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). ## 🔧 HOW TO USE: 1. Install the extension. 2. Open any YouTube video with a Live Chat (or replay). 3. The danmaku will appear automatically! 4. Click the extension icon to adjust settings or toggle the "Hide Chat Window" mode for a cleaner view. ## 📂 OPEN SOURCE: [GitHub Repository](https://github.com/devforagirl/YTChatHelper) --- **Disclaimer:** This extension is an independent open-source project and is not affiliated with or endorsed by YouTube or Google Inc.
