An AI dictionary that explains words in context, at your level
Highlight any word on any page and inContext immediately shows its meaning without leaving the article, PDF or website you are reading.
The extension reads the surrounding sentence to choose the sense of the word that actually fits, rather than returning a generic entry.
Explanations are pitched at your language level, so the definition itself uses words you already understand.
Every looked-up word, plus the sentence you found it in, is stored in the side panel for later revision.
Learn languages with dual subtitles and a hover dictionary in any video
Watch with the subtitle of the language you are learning and your native language stacked, one line above the other, directly inside the video player.
Hover any subtitle word and the video pauses while a pop-up shows an AI-generated definition plus a translation of the surrounding context.
Every word you look up lands in your Wordbook with its original context, so you build a personal list from scenes you actually watched.
If an episode has no subtitles in your language, InterSub translates them on the fly with AI and shows the translation as the second line.
