How KeyVox Works

No magic, just a short on-device process: record, transcribe, clean up, and insert, one step at a time.

KeyVox records your voice, turns it into text using a model installed on your Mac or iPhone, applies your custom dictionary and formatting preferences, and then inserts the result where you were typing.

Every one of those steps runs on your device once setup is complete. Only the initial model download and optional extras like iCloud sync need an internet connection.

The Path From Your Voice to Finished Text

This covers the dictation process itself. Downloads, purchases, and iCloud sync are separate, optional steps.

What happens on your device

  1. You speakHold your Mac trigger key, or tap the microphone on the KeyVox iPhone keyboard.
  2. Your device transcribes itThe installed Whisper or Parakeet model turns the recording into raw text.
  3. KeyVox cleans it upYour custom dictionary spellings and your saved List or Paragraph preferences are applied.
  4. The text appearsKeyVox inserts the finished text where your cursor is, ready for you to read.

How the Text Actually Gets Inserted

On Mac, KeyVox first tries to place finished text directly in the active text field, with a fallback if a particular app does not support that method. On iPhone, the KeyVox keyboard places text directly into the active text field.

In both cases, KeyVox stops once the text is inserted. It does not automatically submit a form, send a message, or press Return.

Changing Your Mind Without Recording Again

Your writing style through Vibes and your List or Paragraph formatting stay adjustable right after dictation, as long as you have not started editing the text yourself.

On Mac, tap your trigger key to apply or undo the current Vibe, double-tap to cycle between Vibes, and hold the trigger with L or P to toggle list or paragraph formatting. On iPhone, long-press the Vibes key to undo a change, or choose a style and long-press to apply it; the Lists and Paragraphs keys work the same way with a long press.
