Quick Answer
Closed caption extensions add CC to streams you watch or streams you broadcast. For streamers, StreamTranslate is better than any extension — it provides an OBS overlay with real-time CC + translation in 28+ languages. For viewers, browser extensions like "Closed Captions for Twitch, YouTube, X, and TikTok" can display CC on supported streams.
Types of Closed Caption Extensions
There are two types of closed caption extensions:
- Viewer extensions — Display captions while YOU watch a stream (if the streamer has enabled CC).
- Streamer tools — Generate captions on YOUR stream for viewers. These are usually OBS overlays, not browser extensions.
Most streamers searching for a "closed captions extension" actually need a captioning tool for OBS, not a browser extension.
Best Options for Streamers
- StreamTranslate — Not an extension but an OBS Browser Source overlay. Provides real-time CC + translation in 28+ languages. More reliable and customizable than any extension. Try it →
- Pixel Closed Captioning — OBS plugin for basic CC.
- Twitch, YouTube, X, and TikTok Closed Captions Extension — Twitch panel extension that displays CC (requires a captioning source).
Why an OBS Overlay Beats an Extension
Browser extensions are limited by what the browser can access. An OBS Browser Source overlay is embedded directly in your stream — every viewer on every platform sees it automatically. No extension installation required on the viewer's end.
StreamTranslate's overlay approach means your captions work on Twitch, YouTube, X, and TikTok, Kick, or any other platform you stream to.
