NextoVO

Watch in the original language, and actually understand it. NextoVO shows two subtitle languages at once under your video: the one you are learning, and yours right below. Missed a word? Click it, and its definition appears. Without leaving the video, without opening a tab, without waiting for a server. WHAT IT DOES • Two subtitle languages at once, on Netflix and YouTube • Click any word: 90,000 definitions bundled inside the extension • Select several words: 27,000 expressions whose meaning you cannot guess from the words alone — look after, get away with, by the way • Sentence-by-sentence keyboard navigation, to replay a line • Automatic pause at the end of each line, so you have time to read • Draggable, resizable subtitle block; your setting is remembered • Saved words keep the line you met them in • Anki export, free and unlimited, even without a subscription WHY EVERYTHING IS LOCAL Subtitle extensions break when their server breaks. Their users are left staring at an endless loading state, and paying subscribers lose access to what they paid for. NextoVO has no server. The dictionary ships inside the extension. The subtitles are the ones the platform already sends to your browser. Your vocabulary lives in your browser. There is nothing that can go down, and nothing to collect about you: no account, no analytics, no record of what you watch. FREE, AND HONESTLY FREE Everything above is free, with no time limit: both languages, the dictionary, the expressions, the navigation, the automatic pause. The only limit is how many words you can save — 25. And even at the limit, what you saved stays readable, editable and exportable to Anki. Forever, including after you cancel. We cap what you add, never what you already own. Premium — €5/month or €25 for life: • Unlimited vocabulary • Spaced review inside the extension, no need for Anki • Training mode: the translation hidden, revealed on hover • Spanish as a learning language • Richer Anki export and local statistics BEFORE YOU INSTALL On YouTube, the second language only appears if the video actually carries a subtitle track in your language. Many videos only have one. The click-to-define dictionary always works — that is precisely where it matters most. We use no machine translation. The subtitles shown are the ones written by the platform's own translators. NextoVO is an independent extension, not affiliated with Netflix or YouTube. Those names are used here only to describe where the extension works. Definitions from Wiktionary (fr.wiktionary.org), licensed CC BY-SA 4.0.
