What local-first dictation changes.
In Just Speak, local mode means speech recognition happens on the Mac through Whisper. Once the model is downloaded, that workflow does not require an internet connection and does not upload the recording for transcription. This is useful for travel, unstable networks, and conversations you would rather keep off a third-party transcription service.
Local processing has a tradeoff. Speed and accuracy depend on your Mac, the model you select, your microphone, and the language you speak. A cloud service can use larger managed systems without asking your laptop to do the same work.
Optional cloud does not erase the distinction.
Just Speak also supports OpenAI and Groq as explicit, bring-your-own-key choices. When you choose one, audio goes directly to that provider under its terms. Your API key and audio do not pass through a Swingby server. There is no automatic provider switch or hidden fallback from local to cloud.
This makes Just Speak flexible without changing its default. You can stay fully local, or decide that cloud speed is worthwhile for a particular workflow. Read the exact handling details in the Swingby Privacy Policy.
What you give up with a focused tool.
Just Speak is not trying to match every feature of a larger dictation platform. It currently targets Apple Silicon Macs. It does not offer a managed team console, an organization-wide vocabulary system, or native mobile and Windows apps. If those are part of your purchase requirement, Wispr Flow is the more complete option.
If your requirement is simpler, speaking into Mail, Slack, Notes, an IDE, or an AI prompt without adding another subscription, the smaller scope can be the advantage.
