InterSub is a browser extension for interactive dual subtitles and instant word translations. It is designed for language learners who want to understand videos while keeping the original content in view, with support for side-by-side subtitles in the target and native languages. The product works on desktop browsers and connects to popular streaming and learning platforms such as YouTube, Netflix, Prime Video, Coursera, Udemy, LinkedIn Learning, TED, and Crunchyroll. It also saves looked-up words to a personal word list and can sync that vocabulary to mobile apps or Telegram bots for review. ## O que InterSub pode fazer? ### Dual subtitles with on-the-fly translation Watch content with subtitles in both your target language and your native language side by side. If subtitles are unavailable in your language, InterSub can translate them on the fly. ### Instant word lookups Hover over words in subtitles to see an instant definition and context translation without leaving the video. ### Personal vocabulary tracking Save every translated word to a personal Wordbook for later review, with history and frequently checked words available in the profile. ### Mobile review sync Use connected mobile apps, Telegram bots, or Anki-style workflows to review saved words away from the browser. ### Desktop browser support InterSub is available for Google Chrome, Microsoft Edge, and Firefox, and it is designed to work across several major video and course platforms. ### Learning aids for longer viewing sessions The extension recognizes English phrasal verbs, idioms, and compound nouns, and it includes options such as showing subtitles only on pause and using a phone as remote control. ## Casos de uso ### Comprehension while streaming Watch shows, documentaries, or lessons with target-language and native-language subtitles visible at the same time so you can follow the plot without pausing as often. ### Vocabulary building during playback Check unfamiliar words directly in the subtitle line to get an instant translation and context meaning, then save them automatically to your vocabulary list. ### Offline review and spaced practice Review saved words later in mobile apps or Telegram bots, or export them for use in other study tools, to turn viewing sessions into repeat practice. ### Big-screen watching with phone control Use the remote control flow when watching on a larger screen so you can pause, rewind, or inspect subtitles from your phone instead of returning to the computer. ### Course-based language study Study course videos on platforms such as Coursera, Udemy, or LinkedIn Learning while reducing interruptions from subtitle lookups and keeping your attention on the lesson. ## Perguntas frequentes ### What is InterSub and how does it work?
