Captionglass
Live subtitles for anything your Mac plays.
Captionglass listens to the sound coming out of your Mac, writes it down, and shows a translated subtitle band on screen. Drop in a video and get a translated .srt. All on your Mac.
Apple Silicon · macOS 14.2 or later
Two things, done well.
Live subtitles
Play a video, join a meeting, open a stream. Captionglass picks up the system sound, transcribes it, translates it, and shows the result in a band at the bottom of your screen. Show the original and the translation together, or the translation alone.
Video to .srt
Drop in a video file and get a translated subtitle file you can use in any player or editor. The free plan covers one video up to 10 minutes.
Your audio stays on your Mac.
Speech recognition runs on your Mac. Translation runs on a local language model through Ollama. No audio and no subtitles are sent to the internet, so it works on private calls and unreleased footage. The only thing that goes online is the license check, which sends a hash of your key, a hash of a device identifier, and the Mac’s name.
Speaks four languages.
- Transcription
- Japanese · Korean · English · Chinese
- Subtitles
- Korean · English · Japanese · Chinese
Show the original and the translation together, or the translation only.

Questions
Do I need an internet connection?
Not to caption or translate. Audio and subtitles never leave your Mac. You need a connection to download the app, the runtime and models the first time, and for the periodic license check.
What is your refund policy?
Ask within 14 days of purchase and we refund you in full. Write to support@raynear.xyz or request it through Paddle (paddle.net). A refunded key stops working. See the Refund Policy.
I got a new Mac. What happens to my license?
In the app menu choose “Deactivate this Mac”, then enter your key on the new Mac. A license works on 2 Macs at a time.
Which apps’ sound does it caption?
All system sound: YouTube, Netflix, meeting apps, a local video player, anything that plays through your Mac’s speakers.
Does it run on Intel Macs?
No. Captionglass needs Apple Silicon.
