Display Mac System Audio as Live Captions
When your Mac plays a call, meeting, video, browser tab, or app sound, Caption captures the system audio and displays the spoken content as live text.
Follow sound from the Mac
Select system audio before the session, start playback, and read new caption lines as the sound continues.
Add your voice and a specific app
Use the microphone with system audio to include your side of a call. Select a specific app when the session centers on that app’s sound. Caption keeps the selected sources in the same session.
Use the text during and after playback
Read the live captions during a meeting, training video, demo, or media review. Save the session to review, revise, export, and search the subtitles by time later.
