About InterSub
InterSub is a dual subtitles and translator extension for Chrome, Edge and Firefox: watch YouTube, Netflix, Prime Video, Crunchyroll and TED, or courses on Coursera, Udemy and LinkedIn Learning, with the subtitle and its translation on screen. Hover over any word and the video pauses to show a pop-up dictionary with an AI-generated definition and context translation, and every word you look up goes to your Wordbook - trainable in a Telegram bot with spaced repetition or synced with Anki.
