Mochi Subs – Live Subtitle Translator for Crunchyroll

Translate Crunchyroll subtitles into 19 languages in real time, on-device. Works with burned-in subs and Picture-in-Picture.

Watch Crunchyroll with subtitles in your language. Mochi Subs translates subtitles in real time with the translator built into Chrome — everything runs on your device. NEW IN 2.0 • Picture-in-Picture with subtitles: keep watching in a floating window, with the translation, while you use other tabs. • Redesigned popup with one-click subtitle styles. • New icon and more reliable episode switching. TRANSLATE INTO 19 LANGUAGES Arabic · Chinese (Simplified) · Chinese (Traditional) · Dutch · English · French · German · Hindi · Indonesian · Italian · Japanese · Korean · Polish · Portuguese · Russian · Spanish · Thai · Turkish · Vietnamese Translation works from any subtitle track Crunchyroll offers for the episode in one of these languages. Chrome downloads each language pack the first time it's used. WORKS WITH EVERY KIND OF SUBTITLE • Regular text subtitles. • Closed captions (CC), when they are the only track in your language. • Subtitles burned into the video: Mochi Subs switches to the clean video and shows only the translation (or covers the original line with an adjustable box, if you prefer). SMART TRACK CHOICE • Uses your preferred subtitle language; if it isn't available, it picks the best alternative. • The badge on the video always shows the real pair, e.g. FR→EN, and tells you when closed captions or a fallback track are in use. • No translation when the subtitle is already in your language. PICTURE-IN-PICTURE WITH SUBTITLES (EXPERIMENTAL) • Floating window with the video, the translated subtitles and simple controls (play/pause, ±10 s, progress). • Open it from the button in the player, from the extension popup or with Alt+P. • Subtitles keep updating while the Crunchyroll tab is in the background. MAKE IT YOURS • One-click styles: Original, Box, Yellow, Large and Soft. • Or customize: size, font, bold, color, outline, height on screen, background color, opacity, padding and rounded corners — with a live preview. • Option to show the original line below the translation, smaller, for language learning. PRIVATE BY DESIGN • Translation runs on your device with Chrome's built-in Translator API. • No accounts, no analytics, no external servers. Subtitles never leave your browser. • The only permission used is "storage", to save your settings. REQUIREMENTS • Chrome 138 or later on desktop. • The first time you use a language pair, click the video so Chrome can download the language pack. Interface in English and Portuguese.
