Turns your voice into keystrokes on Apple Silicon Macs
Hex transcribes your voice and pastes it straight into the app you’re already typing in, no context switching required.

What it does
Hex sits in the background until you press a global hotkey, then records your voice and drops the transcribed text directly into the active application. It behaves like a system-wide dictation shortcut that actually understands where your cursor is. You can hold the key to talk, or double-tap it to lock recording until you tap again.
The interesting bit
The app supports two entirely different transcription backends: a cloud-optimized Parakeet model via FluidAudio for speed and multilingual support, and WhisperKit for entirely on-device processing. It also uses the Swift Composable Architecture, which is unusual for a simple utility and suggests the author plans to keep the logic maintainable as it grows.
Key highlights
- Runs only on Apple Silicon Macs; Intel Macs need not apply.
- Two transcription backends: cloud-optimized Parakeet via
FluidAudio, or on-deviceWhisperKitfor offline use. - Global hotkey injection requires microphone and accessibility permissions.
- Two recording modes: momentary press-and-hold or toggle-style double-tap.
- Open source under MIT, though the author is currently prioritizing issue reports over significant external contributions.
Caveats
- Apple Silicon only; Intel Macs are explicitly unsupported.
- Accessibility permissions are mandatory, which may give privacy-conscious users pause.
- The project is evolving rapidly and the author is not actively reviewing pull requests for core logic changes.
Verdict
Ideal for developers or writers on M-series Macs who want dictation without breaking flow. Skip it if you’re on Intel, wary of accessibility access, or looking to land a major PR right now.
