Inject external items into YouTube's Subscriptions feed that look like videos but link elsewhere.

Features & Capabilities

Inject external items into YouTube's Subscriptions feed that look like videos but link elsewhere.

Features • Follow any show by name and TVSubs will pull the newest two episodes via the TVMaze API. • Cards display real air dates, durations, and fallback artwork so they blend in alongside YouTube uploads. • External links are clearly labelled and open in a separate tab

How to use

  1. Install the extension and open the TVSubs popup.
  2. Enter a show name and the destination link you want (official site, streaming app, etc.).
  3. Visit https://www.youtube.com/feed/subscriptions and refresh — the newest two episodes per show appear as external cards.
  4. You can unfollow shows or change their link at any time from the popup.

Privacy & data collection • No sign-in is required. • The extension does not collect, store, or transmit personal data. • Requests are made only to YouTube (to insert the cards) and TVMaze (to fetch public episode metadata). • All data stays in your browser’s local storage.

Permissions • storage — used to save the list of followed shows and chosen links. • https://www.youtube.com/ — required to inject the cards on the Subscriptions feed. • https://api.tvmaze.com/ — used to download episode titles, thumbnails, and air dates.
