Scientific Typing™
Hold, Speak, Done
The Problem
Typing breaks flow.
Switching apps kills momentum.
Copy-paste is not a workflow.
The Method

Add names, brands & technical terms so ASR never mishears them.
Track words dictated, time saved, and accuracy trends.
Voice data is processed securely via enterprise-grade cloud ASR. We never store your audio.
Keyboard Shortcuts

Get Started
macOS 12.0+ required
Currently (Phase 1), only Macs with Apple Silicon (M1/M2/M3, etc.) are supported. Support for Intel architecture is on our roadmap.
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.
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.
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.
