Twinread: Dual Subtitles on YouTube & Bilingual Page Translator

Two languages at once: dual subtitles on YouTube and other videos, and on-device translation under each paragraph of a page.

• Video on YouTube and other sites: each line in two languages, the whole video, a transcript beside the player, a pause after each line, a repeat, a click on any word for its translation • 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: the browser's built-in on-device translator. No account. Page text stays on your computer unless you add your own DeepL or OpenAI-compatible key; with a key, the text being translated goes to that provider. Free: any page, the whole video, a starter list of saved words. Pro: unlimited saved words, transcript export, Anki and CSV word export, bilingual copy of a PDF, article copies. Pro comes as a timed pass or Pro forever. Trial: one full copy of each export (Anki, CSV word list, PDF copy, article copy, transcript). Sent: your licence key, the product name and a random install id, when you activate Pro and at most once a day after that. Kept phrases go to Anki on your computer when you press Send to Anki. Text goes to your own provider only after you save its key.
