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. The first three take a free key of your own, a minute to get. • 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. Once one is installed, lookups work with no internet at all. • 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, recognised on your device. The picture never leaves it. • 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 Jitendex, JMdict in eight languages, JMnedict, KANJIDIC with JLPT levels, and JMdict's example-sentence build. Sixteen dictionaries, one click each. 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 words, progress and settings stay in your browser. No account, no server, no analytics, nothing that reaches me. Chrome's data disclosure counts text an extension merely reads on your own machine, so the privacy policy spells out what each declared category actually is. Network requests only when a feature needs one: subtitle search, downloading a dictionary, an online dictionary lookup, pronunciation audio, OCR language data, or an AI feature you turned on with your own key. Online lookups and the AI features are off until you switch them on, and the welcome page asks you once. 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.
