Vidoumo
Learn Japanese on YouTube with embedded language tools.
Vidoumo reads the captions YouTube already has and adds the reading over every kanji, the English underneath, and a dictionary behind every word you click. A JLPT level in front of the title tells you how hard the video is before you press play.
I studied Japanese at university, back when a tool like this wasn't possible. Reading meant a dictionary and a lot of patience. YouTube now has captions for almost everything, but they are a native-speaker tool, not a learner tool: no readings over the kanji, English that arrives late or not at all, and a dictionary tab you have to keep switching to.
Vidoumo puts the reading over every kanji, idiomatic and human-written English underneath, and a dictionary card for every word you click. Clicking pauses the video. Save the word and it keeps the sentence and a link back to that moment.
The English comes from the uploader's own subtitles first, then YouTube's translation rebuilt into whole sentences. Google Translate is the last resort, and it only sees a line when nothing else exists.
The newest thing is a JLPT level estimate in front of the video title, say "JLPT N3–N4", so you can tell how hard a video is before you commit to it. It's worked out from the vocabulary, the kanji and how fast people speak. It's a guide, not a rating, because the JLPT publishes no official word lists.
There are no accounts, no analytics and no servers. Everything stays in your browser, including the level estimate.
I'd like to know which videos it handles badly. Songs and very fast speech are where I expect it to struggle.
