No GPU. No download. No configuration.
StreamTranslate runs in the cloud — paste one URL into OBS and go live. Works on any laptop or PC. Unlike local AI tools, there's nothing to install or configure.
The Fastest Way to Get OBS Stream Subtitles
Adding OBS stream subtitles used to mean installing plugins, configuring API keys, and praying your GPU could handle the load. In 2026, it takes two minutes and zero installs. StreamTranslate runs entirely in your browser and delivers subtitles to OBS through a standard browser source — the same way you add alerts or webcam frames.
Twitch, YouTube, X, and TikTok averages 26 million daily visitors (Twitch internal data, 2024), and 57% of internet users prefer content in their native language (CSA Research). Adding translated subtitles to your stream means you're not just captioning — you're opening your content to millions of viewers who couldn't understand you before.
How to Add Subtitles to Your Stream
Create your room on StreamTranslate
Go to streamtranslate.live/control, pick your speaking language and the subtitle language. You get a unique overlay URL instantly.
Add the Browser Source in OBS
In OBS, click "+" under Sources, select "Browser Source," and paste your overlay URL. Set width to 1920 and height to 1080. That's it — no plugin install required.
Position and go live
Drag the subtitle overlay to the bottom of your scene. Start streaming — subtitles appear automatically when you speak. Visit our setup guide if you need help positioning.
StreamTranslate vs Other OBS Subtitle Tools
There are several ways to add subtitles to an OBS stream. Here's how they compare:
| Feature | StreamTranslate | LocalVocal | stream-cc |
|---|---|---|---|
| Setup time | 2 minutes | 15–30 minutes | 5–10 minutes |
| Install required | No — browser source URL | Yes — OBS plugin + model download | Yes — browser extension |
| GPU required | No | Yes (dedicated GPU recommended) | No |
| Translation | 28+ languages | Limited (local models) | English captions only |
| Works on any machine | Yes — cloud-based | No — needs GPU | Partially |
| Latency | <2 seconds | 2–5 seconds | 1–3 seconds |
LocalVocal is a popular OBS plugin that runs AI models locally — but it requires a dedicated GPU, a significant download, and manual model configuration. If you're on a laptop or a machine without a strong GPU, it won't work well. It also has limited translation support compared to cloud-based tools.
stream-cc provides English closed captions but doesn't translate. If your goal is reaching international viewers — not just captioning for English speakers — stream-cc won't help.
StreamTranslate handles both transcription and translation, runs entirely in the cloud, and works on any machine with a browser. No GPU, no plugin, no configuration files.
Why OBS Stream Subtitles Matter in 2026
The global live streaming market is projected to reach $247 billion by 2027 (Grand View Research). As the market grows, so does competition for viewers. Subtitles give you an edge: live streams with subtitles see up to 80% more likely to watch an entire video when captions are available (Verizon Media, 2019) because viewers stay longer when they can follow every word — even in noisy environments or when watching on mute.
- Reach international viewers — Spanish alone has 600 million speakers worldwide (Instituto Cervantes, 2024)
- Improve accessibility for deaf and hard-of-hearing viewers
- Boost watch time and engagement metrics
- Stand out in saturated categories on Twitch, Kick, and YouTube, X, and TikTok
- Works in OBS, Streamlabs OBS, and XSplit
