Overview

Product summary

Review the store description, core capabilities, and common use cases.

Extends capabilities of TwoSeven to synchronize content from streaming platforms such as Netflix, Hulu and several others. In addition, the extension will detect supported videos from many, many other websites, and provide an easy way to watch together.

Simply install the extension, login, and head over to the website where the video you want to watch together exists. The extension will report any supported videos that it found. Click on the TwoSeven extension icon, and select which video you would like to watch together. The extension will automatically load it in an existing TwoSeven room if you're part of one, or create a new room with this video.

The video sharing functionality works perfectly fine! But after installing this, chrome stopped loading .pdf files so i had to disable it each time :(

Why does this app need so much permissions? Be warned.

AI product read

TwoSeven Extension enables synchronized co-watching of videos from streaming platforms (Netflix, Hulu, Amazon Prime, Disney+, HBO Max, YouTube, Crunchyroll, etc.) with friends on twoseven.xyz

Enables remote friends/family to watch videos together in sync, regardless of which streaming platform the content is on, by synchronizing playback state across multiple users

User installs extension → logs into TwoSeven account → visits a streaming platform → extension detects video content → user clicks extension icon → selects video → extension loads video in a TwoSeven room (existing or new) → multiple users join room → video playback is synchronized across all participants

Target users: Friends and family who want to watch content together remotely / Long-distance couples / Online communities who co-watch content / Users of streaming platforms who want synchronized viewing experiences

Cannot verify if twoseven.xyz web service itself has paid tiers without visiting the website
Popup UI content is minified JavaScript making it difficult to verify exact login flow presentation
Cannot confirm if all streaming platform integrations are fully functional from static analysis alone

Monetization

No paid features detected

No evidence of paid features, subscription gating, or payment processing within the extension. 'premium' keyword matches are from Plyr media player library's toggleYouTubeCaptions function. 'subscribe' matches are EventEmitter patterns. 'stripe' matches are CSS is-striped table styling. No billing APIs, payment UI, or upgrade prompts found. ko-fi.com references are embedded donation widget styling only.

Confidence: 85
Payment platform: --
Source: AI / High
Login required: Yes
Reason: The extension implements OAuth authentication with twoseven.xyz using chrome.identity.launchWebAuthFlow. Background script defines LOGIN_DOMAIN='twoseven.xyz' and OAUTH_DOMAIN='auth.twoseven.xyz' with full token management (access_token, id_token, refresh_token). Store description explicitly states 'Simply install the extension, login, and head over to the website'. Login is required to use the TwoSeven co-watching service.
