Sayline

On a Mac, Sayline lets you dictate into any text field instead of typing. It is a native macOS voice dictation app that runs locally, so what you say is turned into text on your machine.

You trigger it with global hotkeys, which means the same shortcut works in Gmail, Slack, VS Code, Notes and other apps.

Privacy is the main selling point.

Sayline uses on-device processing built on NVIDIA Parakeet and MLX, and the audio and resulting data stay on your Mac rather than going to a cloud service.

That matters if you dictate email, code comments or internal chat messages you would rather not upload anywhere.

The developer claims Sayline is about 4x faster than typing by hand.

Use that as a vendor figure, since speed depends on how you speak and what you write.

As a speech-to-text tool it is built for Mac users who want fast, private dictation without switching between apps.
