VTubers face a unique challenge: building global audiences across language barriers. StreamTranslate helps VTubers add real-time translated subtitles to their streams via OBS browser source — reaching English, Japanese, Korean, Spanish, and other language audiences simultaneously.

Why VTubers Use StreamTranslate

Many VTubers stream in Japanese but want to reach English-speaking global audiences. Others stream in English and want to grow their Japanese or Korean fanbase. StreamTranslate handles both use cases — it transcribes whatever language you speak and translates it into your target audience's language in real time.

The overlay works perfectly with VTuber setups — it's transparent, customizable in position, and adds zero GPU overhead (since it's cloud-based). It works with any Live2D or 3D VTuber setup in OBS.
