InterSub

Learn languages with dual subtitles and a hover dictionary in any video

Dual subtitles in your two languages

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 pop-up dictionary

Hover any subtitle word and the video pauses while a pop-up shows an AI-generated definition plus a translation of the surrounding context.

Self-filling vocabulary builder

Every word you look up lands in your Wordbook with its original context, so you build a personal list from scenes you actually watched.

AI subtitle translation

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.
