Every neighbourhood has its own story.
Open a video
Any YouTube video with Japanese captions, including auto-generated ones. CaptionLearn fetches the transcript and keeps it in sync with the player.
Tap a word
The video pauses and you get the meaning of that word as it is used in that sentence, in your own language, not a dictionary list. Powered by DeepL.
Keep it, with its context
Saved words are grouped by base form. Each one remembers its sentence and timestamp, so you can jump back and hear it again.
Japanese is written without spaces. CaptionLearn splits each line into words, so you tap a whole word, not one character at a time.

Questions
- Which Japanese videos work with CaptionLearn?
- Any YouTube video that has Japanese captions, either uploaded by the creator or auto-generated by YouTube. If a video only has captions in other languages, CaptionLearn tells you which ones it found.
- Do I need to know Japanese already?
- No. Beginners tap more words, advanced learners tap fewer. The meaning you get is for the word as it is used in that sentence, which is what makes it useful at every level.
- What does a lookup cost?
- A lookup is one tap on a word. The Free plan includes 30 lookups a month; Learner has 1,000 and Fluent 5,000. Looking at a word you or anyone else already looked up in the same video is free.
- In which languages can I get the meanings?
- Meanings can be shown in German, English, French, Spanish, Italian, Portuguese, Dutch, Polish, Swedish, Danish, Turkish, Ukrainian, Russian, Japanese, Chinese, or Korean. Change it in your account.
