Readable dual subtitles.
Learning line first. Familiar line underneath. Stable sizing and contrast, so both lines stay easy to scan.

Product
Less pausing. More watching.
Built for people who use shows as listening practice: readable dual subtitles, phrase lookup, replay, and saved lines with context.
Phrase lookup, not just word lookup.
Click a word or drag across the whole phrase. The explanation stays in the video, where the context still makes sense.
Replay without scrubbing.
Alt-R jumps back to the current subtitle line, so you can hear it again without hunting through the timeline.
Premium explains the parts subtitles miss.
Idioms, grammar turns, tone, and context when a literal translation is accurate but not especially useful.
Save the line with the word.
Keep vocabulary attached to the sentence where you found it, then export to CSV or Anki when you are ready to review.
Built for real viewing sessions.
Works on desktop Chrome with Netflix and YouTube, including YouTube auto-translate captions when available.
Privacy
Your watch history stays out of it.
Settings, saved words, and free lookups stay in Chrome extension storage. Premium sends the selected phrase, nearby subtitle line, and language pair so the answer has context. Not the page. Not your history.
