Maestra has a Chrome extension for live voice captioning. StreamTranslate has a Twitch extension and OBS overlay — better for streaming audiences who need to see captions, not just you.
Start Free TrialSetup GuideThis is the question that determines which tool is right for a streamer. A Chrome extension for live voice captioning shows captions to you — the person running the extension in their browser. An OBS overlay or Twitch extension shows captions to your viewers — the hundreds or thousands of people watching your stream.
Maestra has a Chrome browser extension that captures voice and displays captions in your browser. This is useful for the person speaking — they can see what is being transcribed. But your viewers on Twitch, YouTube, or Kick cannot see those captions. They are entirely inside your browser window.
StreamTranslate solves the viewer problem. The OBS Browser Source URL creates a caption overlay that goes directly into your stream — so everyone watching can see the captions. The Twitch extension takes this further by delivering captions directly to the Twitch viewer layer, where individual viewers can toggle them on or off.
Maestra Chrome extension is a live voice translation tool that runs in the browser. You speak, it captures audio, it displays translated captions on your screen in real time. This has genuine utility for people who need real-time translation for themselves — international meetings, language learning, conversation assistance. It is not a streaming tool.
StreamTranslate generates an OBS Browser Source URL. When you add this to OBS as a Browser Source and position it on your scene, the caption overlay becomes part of your stream output. Every viewer watching your stream on Twitch, YouTube, Kick, or any other platform sees the captions as part of the video they are watching — exactly like professional broadcast closed captions.
The Twitch extension adds another layer: viewer-side toggleable captions. Viewers who want captions enable them through the Twitch panel. Viewers who do not want captions do not see them. This is how professional broadcast captioning works and it is only available through StreamTranslate.

Stream accessibility is about your audience, not you. If captions only appear on your screen, they serve no viewer accessibility purpose. Viewers who are deaf or hard of hearing, viewers who speak a different language, viewers in loud environments who cannot hear your audio — they all benefit from captions in the stream itself, not just on the streamer browser. StreamTranslate is built with this in mind. The captions go into the stream. The Twitch extension puts captions in the Twitch viewer UI. Every part of the product is oriented toward your audience seeing the captions, not just you.
Visit the setup page to get your OBS Browser Source URL. Add it in OBS, position it on your scene, and your viewers immediately have live captions with real-time translation in 50+ languages. For the Twitch extension, install it from the Twitch Extension Store and activate it on your channel.
No. Maestra Chrome extension shows captions in your browser to you. Your stream viewers cannot see them. StreamTranslate OBS overlay and Twitch extension put captions where your viewers can see them.
A Chrome extension runs in your browser. A Twitch extension runs in the Twitch viewer interface and is visible to your audience watching the stream. StreamTranslate has a Twitch extension.
Via OBS Browser Source overlay (all viewers see it as part of the video) and via the native Twitch extension (viewers can toggle it themselves in the Twitch panel).
Yes via the Twitch extension. Viewers who want captions enable them. Viewers who do not want captions do not see them.
StreamTranslate is not a Chrome extension — it is an OBS Browser Source overlay and Twitch extension. This is intentional: it puts captions in your stream for viewers, not just in your browser for you.
