Twinread: Dual Subtitles on YouTube & Bilingual Page Translator

Dual subtitles on YouTube and other videos, and the translation under each paragraph of a page. No account, no quota, on-device.

Learning a language from the videos and articles you already watch and read? Twinread puts the translation under the original: dual subtitles on YouTube and other video sites, and a bilingual view of any web page, paragraph by paragraph. • Dual subtitles for the whole video, a transcript beside the player, a pause after each line, a repeat, and a translation for any word you click • Bilingual page translator: the translation under each paragraph, or the translation alone • Phrases you keep, saved with the sentence they came from, to review later • PDFs and your own subtitle files, read the same way Translation runs on the browser's built-in on-device translator: no account, and page text is never sent anywhere. Own-key translation with DeepL or an OpenAI-compatible endpoint is off until you add a key; it sends the text being translated to that provider and nothing else. Free: any page, subtitles for the first 10 minutes of each video, 200 saved words. Pro: subtitles for the whole video, unlimited saved words with Anki export, transcript export, and PDF study mode. Sent: your licence key when it is checked. Nothing else. PERMISSIONS • activeTab: the page you are on, when you press the toolbar button or a shortcut • scripting: adds the translation to the page you pick • storage: settings, glossary, kept phrases and licence key, kept on your computer • unlimitedStorage: lets a long list of kept phrases grow past the browser's default storage cap • optional access to any site you choose: asked one site at a time, when you switch on Always translate for it • optional access to www.youtube.com: asked when you switch on the player button on YouTube pages • optional access to your translation provider's host: asked when you save an own-key setting Every feature in detail, guides and the changelog: https://twinread.pages.dev Roadmap: https://twinread.pages.dev/roadmap Twinread is not affiliated with Google.
