CAPABILITIES / Mac work

Built for the places you already type.

Cursor ready

Press once. Speak into the app you were already using.

Just Speak records, transcribes with local Whisper, and inserts the text into the active field.

Dictation

Focused on transcription

No writing assistant layer. The product is built around fast local dictation and cursor paste.

Local

Whisper runs on your Mac

Speech recognition runs locally via whisper.cpp. Your audio does not need to leave your machine.

Model

Smart model picker

Just Speak recommends the right Whisper model for your hardware: accurate enough without melting your fans.

Your choice

No API key required for local mode

Use local Whisper offline, or explicitly choose OpenAI or Groq with your own API key when cloud speed matters.

Languages

English and Korean UI

A bilingual interface for Mac work, with dictation in every language Whisper understands.

PRIVACY / BY ARCHITECTURE

Your voice stays yours.

Dictation hears everything you say. Local Whisper keeps that work on your Mac by default.

  • Speech recognition runs locally (whisper.cpp)
  • Local Whisper works without uploading audio
  • No account required for the trial
  • Transcript history stays local when enabled
  • Optional cloud audio goes directly to your selected provider
FAQ / Before launch

Before you ask

Is this a subscription?

No. One payment, yours forever. Early Access buyers get lifetime Just Speak app updates while the product is actively maintained and distributed. This does not guarantee indefinite maintenance, every future feature, every future macOS compatibility fix, third-party service availability, or support forever.

Does my voice leave my Mac?

Local Whisper is the default and works without uploading audio. If you explicitly select OpenAI or Groq, Just Speak sends audio directly to that provider using your own API key; it does not pass through Swingby servers.

How accurate is local Whisper?

Accuracy varies by model, language, speaking style, microphone quality, and background noise. Just Speak recommends a model for your hardware, and the free trial lets you test it with your own voice and everyday apps.

What happens when the trial ends?

New dictations pause. Your settings and history stay accessible, and entering a license key picks up right where you left off.
