FAQ
Common VTuber questions
What is the best translation tool for VTubers?
StreamTranslate is the easiest VTuber stream translation tool. It adds real-time subtitles as a browser source in OBS or any streaming software — no download, no GPU usage, no configuration beyond pasting a URL. Setup takes under 2 minutes.
How do I add subtitles to my VTuber stream?
Go to streamtranslate.live/control, pick your language pair (e.g. Japanese → English), copy the browser source URL, and add it as a Browser Source in OBS at 1920×1080. Subtitles appear live on your stream automatically.
Will StreamTranslate conflict with VSeeFace or VTube Studio?
No. StreamTranslate is a standalone browser source overlay. It runs independently and has zero interaction with VSeeFace, VTube Studio, or any other avatar software. Layer it above or below your avatar in OBS with no issues.
Do I need a powerful PC to use StreamTranslate?
No. All translation processing happens in the cloud — no local AI or GPU workload. This is especially helpful for VTubers already using CPU/GPU resources for their avatar software and streaming.
Can Japanese VTubers get real-time English subtitles?
Yes. StreamTranslate supports Japanese → English translation with under 2-second latency. Perfect for Hololive, Nijisanji JP, and indie Japanese VTubers wanting to grow their international audience.
Is there a free trial?
Yes. Test StreamTranslate with a free 15-minute preview — no account needed. Sign up with your email for a free 6-hour trial with full access. No credit card required.
What streaming platforms does StreamTranslate work with?
StreamTranslate works with any platform: Twitch, YouTube Live, X, and TikTok, Kick, Bilibili, and more. Because it runs as a browser source overlay in your streaming software, the destination platform doesn't matter.
