Better than a pop-up dictionary: Most online dictionaries still use outdated word look-up systems created years ago that provide a list of candidate words. Interlign determines the correct sense of the word from context and translates morphological parts that other systems often miss.

Interlign reads 떠나야지만 알 수 있는 게 있죠 as leave-must-only know can existing thing exist-right while lookup misreads 알, 수, and 게.
Interlign reads 그렇게 찢어발기지 좀 말라고 좀 as like-that tear-rip-open-don't please don't-said please while lookup loses the negated reported command.
Interlign reads 감싸고 돌잖아 as shield-and go-around-you-know while lookup makes it look like physical wrapping and rotating.

These tools are not just limited to video, we are rapidly building cross-surface usage so that users can learn with whatever they want: books, videogames, apps - anything in your target language
