WatchTwin

Watch videos together in sync: shared playback and live chat on YouTube, Twitch, and any video site.

Watch together, in perfect sync - no matter where you are. WatchTwin turns any video page into a shared watch party. Press play here and it plays for everyone; pause, seek, or switch videos and the whole room follows. A live chat sidebar sits right next to the video so you can react and talk without leaving the page. No accounts. No setup. Just pick a name, share a room code, and you're watching together in seconds. WHAT YOU GET • Synced playback - play, pause, and seek travel instantly to everyone in the room. • Collaborative control - anyone can drive. Change the video and the party comes with you. • Live chat + reactions - a built-in sidebar with messages, typing indicators, and floating emoji reactions. • Watch local files - share a video from your own device with the room, peer-to-peer. • Stays together through YouTube ads- if someone hits an ad, the party waits so no one falls behind. • No account required - just a display name and a room code. Nothing to sign up for. HOW IT WORKS 1. Install WatchTwin and open any page with a video. 2. Click the WatchTwin icon and pick a display name. 3. Create a party (or join one with a room code), then share your code with friends. 4. Watch together - controls and chat stay in sync in real time. WORKS ON Any website with a standard HTML5 video player - YouTube, Vimeo, Twitch, personal and embedded videos, and more. You can also stream a local file to the room. Note: DRM-protected streaming services (Netflix, Disney+, etc.) restrict playback access, so sync generally won't work there. PRIVACY WatchTwin is built to be minimal with your data. No accounts, no emails, no browsing history, no analytics, and no ad tracking. The extension only reads a page's video element while you're actively in a party, and room data is temporary - it's removed once the room is abandoned.
