PRIVATE BY DESIGN
What you hear
stays here.
Speech recognition and translation run on your Mac. No Private Captions server, no account, and no analytics. Your audio and captions stay with you.
Initial setup requires downloads for speech models and translation languages.
Read our privacy policyHow do I get started?
Download Private Captions from the Mac App Store, choose an audio source, and select your spoken and subtitle languages. Complete the model downloads and requested macOS permissions, then start captions.
Can I use it offline?
Transcription and translation run on-device once the required speech model and translation languages are downloaded. You’ll need an internet connection for those initial downloads.
Does Private Captions save my audio?
Audio is discarded after transcription by default. You can optionally enable Save Audio with History to keep recordings locally on your Mac. You control what is saved.
Can I change how captions look?
Yes. Adjust the subtitle font size and background opacity, and choose whether to show the original-language caption alongside the translation.
A WORLD OF WORDS. A LITTLE CLOSER.
Understand more.
In real time.
