On first launch, the extension downloads a ~150MB Opus-MT translation model from Hugging Face's CDN. This is a one-time download — the model is cached in your browser's Cache Storage, so subsequent launches are instantaneous.
Traditional translators send your text to cloud APIs (Google Translate, DeepL, etc.). This extension runs neural inference entirely in your browser via WebAssembly. No subtitle text, no viewing habits, and no personal data ever leaves your device.
The popup UI lets you adjust Swedish and English font sizes independently, swap the text order (Swedish/English vs English/Swedish), toggle between stacked and side-by-side layouts, and reset the overlay position. All preferences persist across sessions.
Yes — the extension intercepts VTT subtitle streams and also has a DOM scraper fallback. It works with news programs, dramas, documentaries, and live broadcasts on svtplay.se, as long as Swedish subtitles are available for the content.
Yes — SVT Play English Subtitles is currently free to download and use. The AI translation model is provided by Helsinki-NLP's Opus-MT project.
This extension was built with a strict privacy-first philosophy.
This extension does not collect, store, transmit, or sell any personal data, browsing history, or viewing habits. Period.
No analytics (Google Analytics, Mixpanel, etc.), no crash reporting, no ad networks, no tracking pixels. The extension has zero dependencies on external services for translation.
Download the extension and enjoy Sweden's premium programs with real-time, local AI subtitles.
