About this app

■ Key Features

• Show multiple language subtitles at once
Display multiple subtitles on a single screen to compare the original and its translation, for a more immersive viewing experience.

• Subtitle generation & translation
Even without subtitles, AI recognizes speech to create them and translates them into the language you want. Choose offline or online AI models to match your needs for accuracy and speed.

• Section repeat
A-B loop, bookmark loop, custom repeat count, and silence skipping — repeat as much as you like until you've fully mastered the key lines.

• Study mode
Use subtitles to repeat listening, dictation, and speaking (shadowing) and pick up your target language naturally.

• Word list & bookmarks
Instantly look up unfamiliar words and save them to your word list, and add important sections to bookmarks to replay and review only the parts you've bookmarked.
