TwoSeven is a watch-together service: you create a room, invite friends, and everyone’s video plays, pauses and skips at the same moment, with chat and optional video calls on the side. YouTube and your own files work straight from the TwoSeven website, while streaming services such as Netflix need the TwoSeven extension for your browser. This guide explains how it works and how to host your first watch party.
What you can watch with TwoSeven
| Source | Extension needed? | What each viewer needs |
|---|---|---|
| YouTube | No | A TwoSeven account |
| Your own video files | No | A TwoSeven account |
| Netflix, Amazon Prime Video, HBO and similar | Yes | Their own subscription to that service |
| Other sites with standard video players | Yes, in many cases | Access to the site |
TwoSeven does not share one person’s streaming account with the room: for paid services, every viewer plays the video from their own account, and TwoSeven keeps the playback in sync.
How to install the TwoSeven extension
- Install it from the Chrome Web Store or from Firefox Add-ons.
- Click the TwoSeven button in the toolbar and sign in with your TwoSeven account.
- Go to the streaming site and open the video you want to watch.
- When the extension says it detected a video, choose Watch on TwoSeven.
How to host a watch party
- Create a room on twoseven.xyz.
- Copy the room link and send it to your friends.
- Pick the video: paste a YouTube link, upload a file, or send a streaming video in with the extension.
- Press play. Anyone in the room can pause or skip, and the change applies to everyone.
Tips for a smooth watch party
- Test ten minutes early. Let everyone open the room and play a few seconds, so sign-in and extension problems are solved before the film starts.
- Use headphones on video calls. Otherwise the film’s sound loops back through everyone’s microphones.
- Agree on subtitles and quality. They are set by each viewer, and a slow connection on full HD causes most sync problems.
- Pick one person to control playback. Anyone can pause, which is handy, but a few people pressing at once makes the video jump.
Why is my friend’s video out of sync?
- Their connection is buffering; lower the video quality on their side.
- They do not have the extension, or are not signed in to it, for a streaming service.
- They are watching a different version of the title, for example another region’s catalogue.
Pausing and pressing play again usually brings everyone back together. Ratings on the Chrome Web Store are mixed, around 3.3 out of 5 as of September 2026, and most complaints are about specific streaming sites changing their players; YouTube rooms tend to work most reliably.
Frequently asked questions
Is TwoSeven free?
Creating rooms and watching together is free. TwoSeven also offers paid options with extra features; check its site for the current details.
Does everyone need Netflix to watch Netflix together?
Yes. Each viewer streams from their own account; TwoSeven only synchronises playback.
How many people can join a room?
Rooms are designed for small groups of friends and family. For a larger audience, check TwoSeven’s help pages for the current limits.
Does it work on phones?
YouTube rooms can be joined from a mobile browser, but the extension, and therefore streaming services, needs a desktop browser.
TwoSeven is a simple way to share a film or a playlist with people in other places. Start with a YouTube room to get the hang of it, then add the TwoSeven extension for streaming nights. For more browser tools, see our list of free YouTube extensions.
