Maestra has a browser-based web captioner. StreamTranslate offers the same plus OBS overlay, 50+ language translation, gaming accuracy, and a Twitch extension — at a third of the price.
Try Free Setup GuideA web captioner is a browser-based tool that uses your microphone to produce real-time speech-to-text output directly in a browser window. You can then display that browser window on your stream — either by capturing it in OBS as a window source, or by using the page as a browser source.
Maestra has a web captioner product that works this way. Open the page, grant microphone access, and the browser produces captions in real time. It's a simple approach that works, but it has limitations for streamers who need the overlay to be clean, transparent, and accurate on gaming audio.
StreamTranslate takes the same core concept — browser-based captioning — and builds a purpose-built streamer experience on top of it. Instead of a general captioner page, StreamTranslate gives you a dedicated Browser Source URL that functions as a transparent overlay widget.
The URL renders only the caption text on a transparent background, positioned and styled for stream overlays. It integrates with OBS as a Browser Source with zero extra steps. And it runs Deepgram Nova-2 on the backend, not a generic web speech API, which means gaming vocabulary and conversational audio are handled with substantially higher accuracy.

Maestra's web captioner produces transcriptions — it shows what you said in your language. StreamTranslate produces transcriptions AND translations — it shows what you said to viewers in their language, simultaneously.
This is the key capability difference that matters for streamers building international audiences. A web captioner that only shows English captions to English speakers isn't significantly expanding your reach. StreamTranslate's translation means every captioned word is instantly available to viewers in 50+ languages — Spanish, Portuguese, Japanese, Korean, German, French, Arabic, and more.
Maestra's web captioner uses standard speech recognition under the hood, which is optimized for clean, formal speech. StreamTranslate uses Deepgram Nova-2, trained on conversational and entertainment audio. The accuracy gap is most visible on gaming-specific vocabulary and in conditions with background audio.
When you say "I'm gonna third-party this dude" or "bro that was so cringe" or reference specific game items, abilities, and character names, Deepgram Nova-2 produces accurate transcriptions where generic speech APIs produce garbled output. For a gaming streamer, caption accuracy on these terms is non-negotiable — wrong captions are worse than no captions.
