SubHamster

Real-time subtitles & translations in up to 3 languages while you watch.

Learn a language while you watch. SubHamster shows live subtitles in up to three languages at the same time — the original, your translation, and a phonetic line (for example Pinyin with tone marks, or Japanese Romaji). Watch your favorite videos and pick up a new language along the way.
