FAQ

1. Are Intel Macs supported?

Currently (Phase 1), only Macs with Apple Silicon (M1/M2/M3, etc.) are supported. Support for Intel architecture is on our roadmap.

2. Why is there no response when I press the Fn key?

Please check: 1. Go to "System Settings -> Privacy & Security -> Accessibility / Microphone" and ensure Comma is checked. 2. Ensure your Mac uses Apple Silicon. 3. Check if other apps are occupying the Fn key.

3. Will there be an iOS or Windows version?

We are currently focused on perfecting the desktop productivity experience on Mac. The mobile version (iOS) is clearly on our roadmap and will follow once the desktop experience meets our standards.

4. Why does the recognized text sometimes duplicate?

Comma's speech engine streams text in real-time. In rare cases of network jitter, the "temporary streaming result" and the "final confirmed result" might briefly overlap. We are actively optimizing the alignment logic to prevent this.
