Interlign

Watch and read Korean with sentence-aware glosses aligned under the original words, then save the exact moment for review.

Demo playback and text glossing are open without an account. Video-pack builds are the downloadable path.

Korean video frame with an Interlign gloss overlay, inline grammar annotation, and English word lookup.

From real media to a saved card

The homepage evidence uses checked-in product captures: glossed media, a context lookup moment, and the mined card made from that same workflow.

Interlign gloss overlay, grammar insight, and word lookup on a Korean video frame
Context glossThe Korean line stays visible while the gloss, grammar note, and lookup stay attached to that moment.

Source momentMining starts from the actual frame being watched, not a detached vocabulary row.

Mined cardThe saved card keeps the frame, Korean line, gloss, translation, and audio together.

Better than a pop-up dictionary: Most online dictionaries still use outdated word look-up systems created years ago that provide a list of candidate words.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.
There are things you can only know after leaving.
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.
Please stop tearing it apart like that.
Interlign reads 감싸고 돌잖아 as shield-and go-around-you-know while lookup makes it look like physical wrapping and rotating.
Why do the two of you keep covering for each other like that?
