Sonora — Live Subtitles & Translation

Sonora adds live bilingual subtitles to any browser tab that plays audio — including the livestreams, lectures and meetings that have no caption track at all. Most subtitle extensions translate the captions a site already publishes, so they go blank the moment a video has none. Sonora listens to the audio itself and transcribes it. That is the whole difference, and it is why there is a cost per hour rather than a free unlimited tier. Once text is settled it is not rewritten, so subtitles stop flickering and second-guessing themselves while you are trying to read them. START IN ONE CLICK After a short sign-in and language setup, click the toolbar icon to start subtitles on the current tab. Click again to stop. The movable overlay keeps its controls beside the words instead of sending you to a separate popup. WHAT IT DOES • Detects the spoken language automatically • Shows the translation and optional original transcript together • Translates into Chinese, English, French, German, Hindi, Indonesian, Italian, Japanese, Korean, Portuguese, Russian, Spanish, or Vietnamese • Works with audio playing in a supported website tab, including meetings and livestreams. Chrome's own pages, the Chrome Web Store, and copy-protected media cannot be captured • Shows your remaining time on the overlay while subtitles run • Pauses automatically when playback stops, so paused time costs nothing PRIVATE BY DESIGN • Capture starts only after you invoke the extension on the current tab • No microphone or camera access • No extension code runs on every website; the overlay is injected on demand • Audio goes from your browser straight to the speech provider that produces the subtitles, over an encrypted connection, using a short-lived credential issued for that session. It never passes through a Live Subtitles server • Audio, transcript text, translation text, tab titles, and visited URLs are not retained by Live Subtitles • Usage history contains only start, end, consumed duration, and status and is retained for 12 months ACCOUNT AND HOURS Sign in with Google. New accounts receive 1 free starter hour. A US$4.99 monthly plan includes 10 hours — 50 cents an hour — or choose a one-time pack: 5 hours for US$3.99, 15 for US$10.99, or 40 for US$24.99. Unused monthly hours reset each billing period; starter and pack hours never expire. Stripe securely handles checkout and billing details. An active session continuously streams tab audio from start to stop, including silence, and consumes time based on audio forwarded for interpretation. Automated subtitles can be delayed or inaccurate, so do not rely on them for emergencies or professional interpretation.
