Romanyt - Romanize for YouTube Captions

Shows Hepburn romaji below Japanese captions on YouTube, including kanji.

Romanyt – Romaji for YouTube Captions Learning Japanese from YouTube just got easier. Romanyt automatically displays Hepburn romaji below Japanese captions as you watch, so you can follow along even when kanji and kana are moving faster than you can read them. What it does Romanyt detects Japanese subtitles on any YouTube video and overlays a romaji reading directly beneath each caption line — in real time, with no manual steps. It uses a full morphological tokenizer (kuromoji) to break Japanese text into words before converting, so readings are accurate rather than character-by-character guesses. Kanji, hiragana, and katakana are all handled. Four display modes Both: Japanese caption on top, romaji below (great for active learners) Romaji only: hides the Japanese and shows only the romanized text Japanese only: turns the extension off without uninstalling it Off: disables all changes to the page Customisable colours Pick any colour for the romaji text from a set of presets or enter your own hex code, so it always stands out against the video background. Who it's for Beginners who haven't learned kana yet and want to get started with real content Intermediate learners building reading speed through shadowing and listening practice Anyone studying Japanese who wants to watch native YouTube content without constantly pausing to look up readings Completely private Everything runs locally in your browser.
