Common questions answered.
How do I add live captions to Chrome?
Install Lessonscriptor from the Chrome Web Store. Open any video, click the extension icon to open the side panel, and hit play. Live captions appear automatically in real-time.
Does Chrome have live captions built in?
Yes, Chrome has a basic live captions feature (Settings → Accessibility → Live Caption). However, it only supports English, produces a read-only feed you can't edit or export, and doesn't handle technical vocabulary well. Lessonscriptor supports 14+ languages and gives you a fully editable, exportable transcript.
Do live captions work with headphones in Chrome?
Lessonscriptor's Premium mode uses tab audio capture — it grabs audio directly from the browser tab rather than through a microphone, so headphones work perfectly.
Can I use live captions for Zoom or Teams recordings in Chrome?
Yes. Lessonscriptor works on any video that plays in Chrome, including Zoom recordings, Google Meet recordings, Teams recordings, and any other video platform.
