# TandemParty > TandemParty is a watch-together service that keeps a video in sync for a group of friends. Playback (play, pause, seek) stays synchronized for everyone in a room, with live text chat and reactions alongside the video. For YouTube, VK Video and RuTube nothing has to be installed — opening the room link in any browser is enough, including on a phone. A Chrome extension extends the same rooms to twelve more streaming services. TandemParty does not host or provide any content — it only synchronizes playback, and every participant watches on their own account on the chosen service. ## What it is TandemParty lets a group watch the same video at the same moment, even from different places. Everyone joins a room through a single link; play, pause and seek performed by the host are applied to everyone, and a live chat with reactions sits next to the video. It is a "watch together" / watch-party tool (an alternative to services like Teleparty), covering both international and Russian streaming platforms. Important: TandemParty is not a streaming service and does not provide any movies or shows. It only synchronizes playback. Every participant must have their own access to the selected platform and its content. ## Two ways to watch There are two paths, and which one applies depends on the streaming service. **Directly on the site, nothing installed.** YouTube, VK Video and RuTube play inside the room page on tandemparty.com. Any modern browser works, on a computer or a phone. A participant only needs to open the invite link and sign in; the room accepts the invitation automatically and the video starts in sync. **With the browser extension.** For the other twelve services the TandemParty extension is required, because playback happens on the streaming site itself. The extension runs in Chrome, Yandex Browser, Microsoft Edge and other Chromium-based browsers. There is no Firefox or Safari version. If a participant without the extension opens a room for a service that is not supported on the site, the room page offers to install the extension instead. ## How to start On a computer, with the extension: 1. Install the TandemParty extension and sign in (email + one-time code). 2. Open a video on a supported streaming site and start playing it. 3. Click the extension icon and create a room; the room name and link are taken from the open tab. 4. Copy the invite link and send it to your friends. On a phone or without installing anything: 1. Open a video in the YouTube, VK Video or RuTube app and tap "Share". 2. Send the link to the Telegram bot @tandemparty_bot. 3. The bot creates a room and replies with an invite link; forward it to your friends. 4. Everyone opens the link and watches in sync, right in the browser. ## Features - Synchronized playback: play, pause, and seek are shared instantly with all room participants. - Watching on the site with no installation for YouTube, VK Video and RuTube, including on phones. - In-room text chat next to the video, with a one-message-per-second limit. - Reactions and animated sticker packs during viewing (Premium). - Room creation from a shared link through the Telegram bot. - Sign-in codes delivered on Telegram when the account is linked, with email as a fallback. - Profile page with avatar, nickname, subscription status and the list of your rooms; profile appearance customization (Premium). - Phone as a remote control via a QR code shown in the browser — no mobile app required. - Resume from the room's saved timecode. - Automatic reconnection after a dropped connection; opening the same room on another device moves playback there instead of fighting over the session. - Interface languages: Russian, English, German, Spanish. ## Plans - Free plan: rooms with up to 2 participants. - Premium: rooms with up to 15 participants, plus reactions, stickers and profile customization. - Premium can also be earned: linking a Telegram account and subscribing to the channel grants 3 days. - Current prices and details: https://tandemparty.com/tarifs ## Requirements - To watch on the site: any modern browser, desktop or mobile.
