View on Chrome Web StoreChrome will indicate if you already have this installed.
Overview
YouTube Live Chat Overlay transforms the standard YouTube live chat sidebar
into a Nico-nico style flowing comment overlay directly over the video.
Watch live streams with chat messages scrolling across the screen — just
like Japanese video sharing platforms.
✨ Features:
• Four display modes — Right-to-left scroll (classic), left-to-right
reverse, top-fixed, bottom-fixed
• Rich content support — Text, emoji, Super Chats (with stickers and
amounts), membership join messages
• Real-time translation — Translate chat messages with dual-language
subtitle display or full replacement (Chrome 138+)
• Multi-language settings UI — English, 한국어, 日本語, Español, 中文
• Backlog injection — Past messages fill the screen when you join a
stream in progress
• Depth layers — Messages separate into near/far visual planes based on
speed for a 3D-like effect
• Author badges — Owner, moderator, and member icons with customizable
colors
• Full customization — Control speed, font, size, opacity, colors, text
outline, safe zones, lane spacing, and more
• Settings import/export — Share configuration across browsers or back
up your preferences
• Cross-tab sync — Settings sync instantly across all YouTube tabs
🔒 100% local processing. Chat content is never recorded, stored, or sent
anywhere. All parsing, rendering, and translation happens inside your browser.
