Live captions
Listens to a microphone and shows closed captions on a black or translucent background, in English or, with an access key, translated to Spanish, Portuguese, Polish, German, French, Italian, Russian, Chinese, Japanese, Korean or Vietnamese. Send this screen to a display, projector or switcher input.
Captions will appear here. Press Start listening, then Full screen to send this to a display.
Translation needs an access key. Without one, captions show in the speaker’s language.
Tips
- Works in Chrome, Edge and Safari. Firefox can’t do speech recognition yet.
- Feed it clean audio: a mix bus or aux into the computer’s line or USB input, or a mic close to the talker. Room mics and loud music lower accuracy. Pick the input in your browser’s site settings or your computer’s sound settings.
- Press Full screen and send the computer’s display output to your switcher or projector. Green or blue screen color lets a keyer drop the background; the black box works for a luma key.
- Captions are machine-made and can be wrong, especially names and technical terms. They aren’t a substitute for a professional captioner where accuracy is required.
- Keyboard: F for full screen, C to clear, Space to start or stop.

Your browser does the listening. Chrome and Edge send the audio to Google or Microsoft to turn it into text, and Safari uses Apple. Recent desktop Chrome translates on your computer. Other browsers send the caption text (not audio) through our server to the DeepL translation service. We don’t keep the audio, the captions or the translations.
