Transcription and offline use

Jarvis transcribes on your Mac by default. That keeps it fast, private, and able to work with no internet at all.

On-device by default

A local speech model runs on your Mac. Smaller models are faster; larger models are more accurate. You can pick the trade-off in settings.

Optional cloud, your key

If you want a cloud transcription service for extra accuracy, you can plug in your own key. The audio then goes from your Mac to that provider, not through us.

Accuracy and speed

• About 240ms from key release to the first word.
• Around 3.1% word error rate on technical English with a mid-size local model.
• Larger models trade a little speed for more accuracy.
