FAQ

Q: Can I transcribe multiple apps simultaneously?

A: Only one app can be selected for transcription at a time, but microphone audio can be recorded simultaneously.

Q: Why is audio from other apps also being transcribed?

A: This is due to system limitations. You can try closing other apps and system sounds.

Q: Why can't I record when an app is full-screen or moved to another Space on macOS?

A: This is due to macOS security restrictions that prevent accessing app screens not in the same hierarchy. Please ensure the app being recorded is in the same hierarchy and not in full-screen mode.

Q: What is the latency of real-time transcription?

A: When device performance is sufficient and GPU acceleration is enabled, latency is typically less than 500ms. If device performance is insufficient, please use real-time models.
