Kitsumi

YouTube/Anime/Netflix subtitle overlay with dictionaries, Anki mining, 46 languages support

Kitsumi - Hover a Word. Understand It. Keep Watching. 🦊 No setup. Press play and study. You're watching something. A word goes by that you don't know. Hover it - reading, definition, grammar, in about a second. Then you keep watching. That's the whole plugin. Everything else is optional. Watching foreign video with English subtitles never really worked. What you actually needed was native subtitles with definitions on demand. Open YouTube and it just works - pick your track and go. Watching anime? Find subs without leaving the page. 🎬 Works on anime, YouTube, Netflix, Crunchyroll, most HTML5 players. 🔍 Hover any subtitle word for an instant lookup. 🧠 Study the line's vocabulary in context. 🃏 Mine a word to Anki in one click. 📈 Watch your history build up. Free. No account. No subscription. No telemetry. 🦊 WHAT YOU CAN DO • Interactive subtitles - hover any word for readings, definitions, part of speech, difficulty and frequency. • Subtitle overlay - your own .srt, .vtt or .ass, restyled and repositioned. • Subtitle search - Jimaku, OpenSubtitles, SubDL and Kitsunekko, without leaving the video. • Precision sync - ±10 ms to ±1000 ms, saved per show. • Study Mode - the current line as a vocabulary session; mark what you know. • Anki mining - word, reading, definition, sentence, screenshot, audio, clip. • Custom dictionaries - Yomitan .zip / .json and plain .tsv wordlists. • 46 languages - Japanese, Spanish, German, French, Korean, Ukrainian, Chinese and more. • Articles Reader - the same hover lookup on any webpage. • OCR - pull text out of images and video frames. • Comprehension target - see how much of a line is new to you. • Stats - words, study time, streaks, active days, cards mined, per language. • 36 ranks and 200+ achievements, earned from what you were doing anyway. • Auto-next episode - carries your setup into the next one. • Overlay or its own window. Your call. 🇯🇵 JAPANESE GETS THE FULL STACK JMdict, JMnedict, KANJIDIC, pitch accent, frequency and JLPT data. Every other language runs on Yomitan-format dictionaries, so you're never stuck with what ships in the box. 🧠 HONEST NOTE It won't learn the language for you. Hovering is recognition; what builds memory is guessing before you look and using the word yourself. Ranks and XP measure activity, not ability. 🔒 PRIVACY Your data stays in your browser. No account, no server, nothing collected. Network requests only when you ask: subtitle search, dictionary download, or an AI feature you enabled with your own key. Kitsumi needs broad site access because subtitles get drawn over players it can't know about in advance, including ones inside embedded frames. Want it tighter? Right-click the icon → "This can read and change site data" → "On specific sites". Everything still works. 🦊 Unknown word → hover → understood → back to the episode.
