Twinread: Dual Subtitles & Page Translator geliştiren: exochard

Watch YouTube with subtitles in two languages, and read any web page with its translation under each paragraph. Twinread is a dual subtitles extension and bilingual page translator for language learners: hear the original, read both lines, pause after each one, and keep the words you want to learn.

Translation runs on your computer. No account.

• 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
• Saved words, each with the sentence it came from, reviewed as flashcards on a spaced schedule, and sent to Anki (Pro)
• PDFs, your own EPUB, text and HTML files, and your own subtitle files, read the same way
• Reading aids on subtitles: furigana and romaji for Japanese, pinyin for Chinese
• A sentence explained, its meaning and grammar, by your own key
• Anki cards with the picture and the sound of the line (Pro)
• The site's own second caption track beside the translation, slow replay of a line and Hear, which reads a word aloud with a voice on your computer

Translation: Bergamot, on your computer.

Free covers any page, the whole video, saved words, a reader for your own files and a few sentence explanations. Pro lifts those limits and adds reading aids without a cap, Anki cards with picture and sound, transcript export, Anki and CSV word export, a bilingual copy of a PDF and article copies. Pro is a pass for a set time or one payment for Pro forever. Full refund within two weeks, no questions asked. Plans, trial and refund terms: https://twinread.exotools.dev/pricing

PRIVACY
Sent to our server: the licence key, the product name, a random id for this browser and the other fields in the privacy policy, when you activate Pro and about once a day after; the trial's start and end, rounded to the hour, when you start a trial, kept only in a cookie in Firefox; a diagnostics report, when you press Send. Each language pair's model downloads from Mozilla on first use, and only the name of the pair is sent. Text goes to a provider only for a language pair you route to your own DeepL or OpenAI-compatible key. Saved words go to Anki on your computer when you press Send to Anki. Firefox asks your permission before the key or the trial's dates leave. Privacy policy: https://twinread.exotools.dev/privacy
