VOD Chat Sync

Show VOD-synced chat in an always-on-top picture-in-picture window. Supports BTTV/FFZ/7TV emotes and click-to-seek.

Replays VOD chat synchronized with video playback in a floating, always-on-top Picture-in-Picture window — so you can keep up with chat while doing something else on the side. ━━━ HIGHLIGHTS ━━━ - Document Picture-in-Picture window — stays visible across virtual desktops, full-screen apps, and other browser tabs. - Two modes: – "Video + Chat" mirrors the VOD into the PiP window via captureStream so you don't need to keep the original tab in the foreground at all. – "Chat only" is the lightest option — chat alone, no video mirror. - Third-party emotes (BetterTTV, FrankerFaceZ, 7TV) — both global and per-channel sets are loaded automatically. Animated emotes work. - Click any chat line to seek the video to that exact timestamp. Great for finding the highlight clip somebody just referenced 30 seconds ago. - Resizable chat width, adjustable opacity, three emote sizes, optional hide-header / hide-status-bar. - Localized in English and Japanese. ━━━ HOW TO USE ━━━ 1. Open any Twitch VOD page (twitch.tv/videos/...). 2. Click the toolbar icon and press "Open PiP now". 3. A floating window appears with chat synced to the video. If the PiP window does not open, click anywhere on the Twitch page first to restore the page's "user activation" state, then try again. Browsers require a recent gesture before opening a PiP window. ━━━ PRIVACY ━━━ - No accounts. No tracking. No analytics. - No data is ever sent to a server operated by the developer. - The only outbound network requests are to Twitch's public chat-replay endpoint and to BTTV / FFZ / 7TV for emote images. - All settings live in chrome.storage on your device.
