Vidoumo

Learn Japanese from YouTube and Netflix with the subtitles they already have. Vidoumo adds the reading over every kanji, the English underneath, and a dictionary behind every word you click. WHAT YOU GET • Furigana over kanji, so you can read the line while you listen. • English under every Japanese line. Where the video has English subtitles, those are used (on Netflix, Netflix's own English subtitles). If not, YouTube's own English translation is used, rebuilt into whole sentences. Only if neither is available does a line go to Google Translate. • Click any word and the video pauses. A card shows the reading, the JLPT level and the meanings. • A JLPT level estimate in front of the video title (for example "JLPT N3–N4"), worked out from the vocabulary, the kanji, the grammar and how fast people speak. On Netflix the speed figure is rougher, because Netflix gives no speech timing. Hover it for the breakdown. A video with too little speech reads "JLPT unrated". It is an estimate, not an official rating. • Save a word with one click. It keeps the sentence it came from and a link back to that moment in the video. • Export your saved words as a CSV file. • Furigana and translation each switch off from the toolbar popup, so the same video works for a beginner and for someone who only wants the dictionary now and then. HOW IT WORKS Vidoumo reads the Japanese subtitles the site already has and draws them in a box over the video. On YouTube that is the captions, manual or automatic. On Netflix it is the subtitle file for the title you are watching, the same one the player downloads. Japanese has no spaces, so the words are found by kuromoji, a tokenizer that is bundled with the extension and runs in your browser. Dictionary entries come from Jisho.org. The level estimate is worked out in your browser from the captions and bundled word, kanji and grammar lists, so nothing extra is sent anywhere. How it works, in full: https://mrfrisby.com/vidoumo/levels PRIVACY There are no accounts, no analytics and no servers of ours. Your saved words and settings stay in your browser. Two outside services are used: Jisho receives the word you click, and Google Translate receives a subtitle line only when there are no English subtitles to use (on YouTube, when YouTube cannot translate the video either). Turn Translation off and no caption text goes to Google. Full policy: https://mrfrisby.com/vidoumo/privacy Vidoumo works on youtube.com and netflix.com.
