Duet Autor: Mich

Watch movies, episodes, and YouTube together when you can't be in the same room.

Duet syncs play, pause, and seek between exactly two browsers in real time, so you and one other person can hit play once and stay together for the whole show — no screen sharing, no group calls, no buffering one side ahead of the other.

How it works
1. Install Duet on both browsers.
2. One person clicks Create a room and shares the 6-character code.
3. The other person types the code in.
4. Both open the same video. Press play. You're in sync.

No accounts, no logins, no setup beyond installing the extension.

Features
- Real-time play, pause, and seek sync
- Drift correction across network latency
- Floating draggable badge with chat + emoji reactions, right on top of the video
- "Sync partner to me" button — snap them to your exact timestamp
- Per-partner display name and avatar
- Works on YouTube, Vimeo, and any site with an HTML5 video element

Limits
- Strictly 2 people per room
- Some DRM-heavy sites (Netflix, Disney+) may have flaky seek sync; free YouTube works perfectly
