What does SonicCaption do?
SonicCaption is a browser extension that listens to audio from any tab—like YouTube, Netflix, Twitch, or Zoom—and generates live subtitles with translation. You install it, pin it to your toolbar, open a video or meeting, and click start. It processes the audio directly in your browser, showing both the original language and your chosen translation side-by-side with minimal delay.
The tool stands out because it works universally on any site that plays audio, requires no file uploads, and operates with very low latency—subtitles appear in about half a second. It offers dual subtitles so you can see the original and translated text simultaneously, and it's designed with privacy in mind: audio processing happens locally, and only text snippets are sent for translation.
This is ideal for language learners watching foreign content, professionals participating in multilingual video calls, or students taking online courses in another language. It helps you follow along without constant pausing or rewinding, making foreign-language media more accessible and less exhausting to consume.
